Mitosis - Worksheet | Distance Learning - Free Printable

Problem Analysis:

The worksheet provided involves labeling the phases of mitosis and answering true/false questions about mitosis. Let's break it down step by step.

#### Q.1: Labeling the Phases of Mitosis
The image shows five stages of mitosis, and we need to label them using the words provided in the box:
- Prophase
- Metaphase
- Anaphase
- Telophase
- Interphase
- Daughter cells

The stages are depicted as follows (from left to right, top to bottom):
1. A cell with chromosomes loosely spread out.
2. Chromosomes are visible and aligned at the center of the cell.
3. Chromosomes are moving apart toward opposite poles.
4. Two separate nuclei are forming, and the cell is beginning to divide.
5. The final stage where two daughter cells are formed.

Now, let’s match these stages with the correct terms:

- First Image (Top Left): This is the initial phase where chromosomes are not yet condensed. This is Interphase.
- Second Image (Top Middle): Chromosomes are visible and aligning at the metaphase plate. This is Metaphase.
- Third Image (Top Right): Chromosomes are moving apart toward opposite poles. This is Anaphase.
- Fourth Image (Bottom Left): Two separate nuclei are forming, and the cell is beginning to divide. This is Telophase.
- Fifth Image (Bottom Right): The final stage where two daughter cells are formed. This is labeled as Daughter cells.

So, the labels should be:
1. Interphase
2. Metaphase
3. Anaphase
4. Telophase
5. Daughter cells

#### Q.2: True/False Statements
We need to evaluate each statement based on our knowledge of mitosis.

1. "Interphase is the 'resting phase' of mitosis."
- True: Interphase is indeed considered the resting phase of the cell cycle. During this phase, the cell grows, replicates its DNA, and prepares for division. Although it is active in growth and replication, it is called the "resting phase" because it is not actively dividing.

2. "In a single-celled organism, mitosis is used for reproduction."
- True: In single-celled organisms, mitosis is the primary method of reproduction. When a single-celled organism undergoes mitosis, it divides into two identical daughter cells, effectively reproducing.

3. "Cell division of mitosis is considered as means of sexual reproduction."
- False: Mitosis is a form of asexual reproduction. It produces two genetically identical daughter cells from a single parent cell. Sexual reproduction involves meiosis, which reduces the chromosome number and leads to genetic variation.

4. "Mitosis is a process that makes exact copies of the original cell."
- True: Mitosis results in two daughter cells that are genetically identical to the parent cell. Each daughter cell receives an exact copy of the genetic material from the parent cell.
