Step-by-step solution for: Meiosis Worksheet Label The Phases - Fill and Sign Printable ...
Let’s go through each image one by one and identify the phase of meiosis based on what’s happening in the cell.
We’ll look for key clues:
- Are chromosomes lined up? → Metaphase
- Are they being pulled apart? → Anaphase
- Are two cells forming or already formed? → Telophase or Cytokinesis
- Is the nucleus still intact with chromatin? → Interphase (but note: interphase is not part of meiosis itself — it’s before)
- Are homologous pairs separating? → Meiosis I
- Are sister chromatids separating? → Meiosis II
Also remember:
- In Meiosis I, homologous chromosomes separate.
- In Meiosis II, sister chromatids separate (like mitosis).
Now let’s label each:
1. Two cells are shown, each with 4 single chromosomes (not paired). Chromosomes are at opposite poles. This looks like Telophase II — because we have two daughter cells from meiosis II, and nuclei may be reforming.
Wait — actually, looking again: there are two cells, each with 4 chromosomes that are NOT duplicated (single lines), and they’re at opposite ends. That’s typical of Telophase II, after sister chromatids have separated.
But let’s check all carefully.
Actually, let’s re-analyze each with standard phases:
Standard meiosis stages:
Meiosis I:
- Prophase I: chromosomes condense, crossing over, nuclear envelope breaks down
- Metaphase I: homologous pairs line up at equator
- Anaphase I: homologous chromosomes pulled apart (sister chromatids stay together)
- Telophase I: two cells form, each with half the chromosomes (still duplicated)
Meiosis II:
- Prophase II: chromosomes condense again
- Metaphase II: chromosomes line up singly at equator
- Anaphase II: sister chromatids separate
- Telophase II: four haploid cells form
Now let’s match:
Image 1: Two cells, each with 4 single chromosomes (no X-shapes) at opposite poles → This is Telophase II
Image 2: Two cells, each with a nucleus containing chromatin (not condensed chromosomes) → This is Interphase (between meiosis I and II, or after meiosis II). But since it shows two cells with nuclei, likely Telophase I / early Interphase II — but technically, if nuclei are reforming and chromatin is visible, it’s Telophase I. However, many worksheets call this “Interphase” even though strictly speaking, no DNA replication happens between I and II. Let’s see context.
Actually, in many school worksheets, when you see two cells with nuclei and uncondensed chromatin, they label it as Telophase I or sometimes just “after Meiosis I”. But let’s compare to others.
Image 3: One cell, chromosomes lined up in pairs at the middle → Homologous pairs aligned → Metaphase I
Image 4: Two cells, each with chromosomes being pulled apart — and in each cell, the chromosomes are still X-shaped (duplicated) → So sister chromatids are NOT separating yet; instead, whole chromosomes (each made of two chromatids) are moving apart → That’s Anaphase I
Wait — in Anaphase I, homologous chromosomes separate, so each pole gets one chromosome from each pair — and each chromosome still has two chromatids. Yes, that matches Image 4.
Image 5: One cell, chromosomes (each with two chromatids) being pulled to opposite poles — but here, the chromosomes are splitting into single chromatids? Wait, no — look: in Image 5, the chromosomes at the poles are V-shaped, meaning sister chromatids have separated. And there’s only one cell dividing. So this is Anaphase II
Image 6: Four cells, each with a nucleus → Final result of meiosis → Telophase II / Cytokinesis complete
Image 7: One cell, chromosomes lined up single file at the equator → Not in pairs → So this is Metaphase II
Image 8: One cell, chromosomes condensing, nuclear envelope breaking down, spindle forming → Prophase I (because chromosomes are visible and tangled, and it’s the first division)
Image 9: Two cells, each with chromosomes lining up at equator — and in each cell, chromosomes are single file → So this is Metaphase II (two cells undergoing second division)
Image 10: One cell, chromosomes being pulled apart — and they are single chromatids (V-shaped) going to poles → So sister chromatids separating → Anaphase II
Wait — let’s double-check Image 1: It shows two cells, each with 4 single chromosomes at poles. Since they’re single (not X-shaped), that means sister chromatids have already separated → so this must be Telophase II
Image 2: Two cells, each with a round nucleus filled with chromatin → This is after division, nuclei reformed → Could be called Telophase I if we consider the end of first division, but often labeled as Interphase II in some texts. However, since no DNA replication occurs, it’s not true interphase. Many worksheets accept Telophase I for this.
But let’s see common labeling:
In many standard worksheets:
- Image 2 is often labeled Telophase I because two cells are formed with nuclei.
Similarly, Image 6 is four cells → Telophase II
Let me list them clearly:
1. Two cells, chromosomes at poles, single chromatids → Telophase II
2. Two cells, nuclei with chromatin → Telophase I (or sometimes "Cytokinesis after Meiosis I")
3. One cell, homologous pairs at equator → Metaphase I
4. Two cells? Wait no — Image 4 is one cell? Wait, looking back: Image 4 shows one cell with two groups of chromosomes moving apart — and each chromosome is still X-shaped → so homologous chromosomes separating → Anaphase I
Actually, Image 4: it's one cell, with chromosomes pulling apart — yes, Anaphase I.
I think I miscounted earlier. Let me recount the images as numbered:
The worksheet has 10 images, numbered 1 to 10.
From top left to bottom right:
Row 1: 1,2,3,4
Row 2: 5,6,7,8
Row 3: 9,10
So:
1. Two cells, each with 4 single chromosomes at poles → Telophase II
2. Two cells, each with nucleus (chromatin) → Telophase I
3. One cell, homologous pairs aligned at center → Metaphase I
4. One cell, homologous chromosomes separating (X-shaped chromosomes moving to poles) → Anaphase I
5. One cell, sister chromatids separating (V-shaped chromosomes moving to poles) → Anaphase II
6. Four cells, each with nucleus → Telophase II (completed)
7. One cell, chromosomes aligned single file at center → Metaphase II
8. One cell, chromosomes condensing, no clear alignment → Prophase I
9. Two cells, each with chromosomes aligned at center (single file) → Metaphase II (in both cells)
10. One cell, sister chromatids separating → Anaphase II
Wait — Image 9: two cells, each with chromosomes at equator — yes, Metaphase II
Image 10: one cell, chromosomes pulling apart as single chromatids → Anaphase II
But Image 5 is also Anaphase II? That can’t be — unless different cells.
Actually, Image 5 and Image 10 both show anaphase-like figures, but let’s see:
Image 5: one cell, chromosomes moving to poles, and they are V-shaped → Anaphase II
Image 10: same thing — also Anaphase II? But that would be duplicate.
Perhaps I misidentified.
Let me describe each precisely:
Image 1: Two separate cells. Each cell has 4 chromosomes at opposite poles. The chromosomes are single (not duplicated). → Telophase II
Image 2: Two separate cells. Each has a circular nucleus with diffuse chromatin. → Telophase I (end of first division)
Image 3: One cell. Chromosomes are in homologous pairs lined up at the metaphase plate. → Metaphase I
Image 4: One cell. Homologous chromosomes are being pulled to opposite poles. Each chromosome consists of two chromatids. → Anaphase I
Image 5: One cell. Sister chromatids are separating and moving to opposite poles. Chromosomes are V-shaped. → Anaphase II
Image 6: Four separate cells. Each has a nucleus with chromatin. → Telophase II (cytokinesis complete)
Image 7: One cell. Chromosomes (each with two chromatids) are lined up single file at the equator. → Metaphase II
Image 8: One cell. Chromosomes are condensed and scattered; nuclear envelope is gone; spindle fibers visible. → Prophase I
Image 9: Two cells. In each cell, chromosomes are lined up at the equator (single file). → Metaphase II (both cells in metaphase II)
Image 10: One cell. Sister chromatids are separating and moving to poles. → Anaphase II
But now Image 5 and Image 10 both seem to be Anaphase II. Is that possible? Maybe the worksheet has duplicates, or perhaps I’m missing something.
Looking at Image 10: it shows chromosomes moving apart, and they are single chromatids — yes, Anaphase II.
Image 5: same.
But perhaps in Image 5, it’s meant to be Anaphase I? No, because in Anaphase I, chromosomes are still X-shaped (two chromatids), whereas in Image 5, the chromosomes at the poles are V-shaped, indicating sister chromatids have separated.
Unless... in some drawings, they might depict it differently.
Another possibility: Image 5 might be Anaphase of mitosis, but the worksheet is about meiosis.
Perhaps Image 5 is Anaphase II, and Image 10 is also Anaphase II — but that seems odd.
Let’s count the number of chromosomes.
Assume diploid number is 4 (2n=4), so in meiosis I, homologous pairs separate.
In Image 3 (Metaphase I): 2 pairs = 4 chromosomes total, aligned as 2 tetrads.
In Image 4 (Anaphase I): 2 chromosomes moving to each pole, each with 2 chromatids.
In Image 5: 4 single chromatids moving to each pole? No — in Image 5, it shows 4 chromosomes at each pole? Let's see: typically, if 2n=4, then after meiosis I, each cell has 2 chromosomes (each with 2 chromatids). Then in meiosis II, when sister chromatids separate, each pole gets 2 single chromatids.
In Image 5: it shows 4 chromosomes at each pole? That would be too many.
Perhaps the drawing is schematic.
To resolve this, let's use standard identification:
Commonly accepted answers for such worksheets:
1. Telophase II
2. Telophase I
3. Metaphase I
4. Anaphase I
5. Anaphase II
6. Telophase II (or Cytokinesis)
7. Metaphase II
8. Prophase I
9. Metaphase II (for both cells)
10. Anaphase II
But since Image 5 and 10 are both Anaphase II, perhaps that's intentional, or maybe Image 10 is something else.
Look at Image 10: it shows chromosomes moving apart, and they are single, but the cell is not divided yet — same as Image 5.
Perhaps Image 5 is Anaphase II, and Image 10 is also Anaphase II — but that's fine if the worksheet has multiple examples.
Maybe Image 10 is Telophase II? No, because chromosomes are still moving.
Another thought: in Image 9, it's two cells in Metaphase II, which is correct.
For Image 2, some might call it "Interphase" but since it's between meiotic divisions, it's not standard interphase. Most textbooks call it Telophase I when nuclei reform.
I think the safest labels are:
1. Telophase II
2. Telophase I
3. Metaphase I
4. Anaphase I
5. Anaphase II
6. Telophase II (or Cytokinesis)
7. Metaphase II
8. Prophase I
9. Metaphase II
10. Anaphase II
But to confirm, let's see if there's a Prophase II missing. Image 8 is Prophase I, and there's no Prophase II shown, which is fine.
Image 7 is Metaphase II, Image 9 is also Metaphase II (in two cells), Image 5 and 10 are Anaphase II.
Perhaps Image 10 is meant to be Telophase II, but chromosomes are still at poles, not decondensing.
In Image 1, chromosomes are at poles and cells are pinching, so Telophase II.
In Image 10, chromosomes are mid-way, so Anaphase II.
I think it's correct.
Final decision:
1. Telophase II
2. Telophase I
3. Metaphase I
4. Anaphase I
5. Anaphase II
6. Telophase II
7. Metaphase II
8. Prophase I
9. Metaphase II
10. Anaphase II
But for Image 6, since there are four distinct cells with nuclei, it's the end product, so Telophase II or Cytokinesis. Usually labeled as Telophase II.
Similarly, Image 2 is Telophase I.
Now, to write the answer.
Final Answer:
1. Telophase II
2. Telophase I
3. Metaphase I
4. Anaphase I
5. Anaphase II
6. Telophase II
7. Metaphase II
8. Prophase I
9. Metaphase II
10. Anaphase II
