Quiz: Cells organelles | Thebiologist | Live - Free Printable

Let’s go step by step to solve each part of the quiz.

---

Part 1: Match the description with a term.

We have these terms to choose from:
- Cell membrane
- Cytoplasm
- Ribosomes
- Golgi body
- Mitochondria
- Nucleus

Now match each letter:

a. “Organelle that releases energy for the cell. The power house of the cell.”
→ That’s Mitochondria. It makes ATP (energy) for the cell.

b. “Structure that forms a boundary of cell. Allows things to enter or leave the cell.”
→ That’s the Cell membrane. It controls what goes in and out.

c. “Gel-like material inside the cell membrane.”
→ That’s Cytoplasm. It’s the jelly stuff where organelles float.

d. “Where proteins are made.”
→ That’s Ribosomes. They build proteins using instructions from DNA.

e. “A folded membrane that moves material in cells. The UPS of a cell.”
→ That’s the Golgi body. It packages and ships materials like a delivery service.

f. “Structure that directs the cell’s activities.”
→ That’s the Nucleus. It holds DNA and tells the cell what to do.

✔ So Part 1 answers:
a. Mitochondria
b. Cell membrane
c. Cytoplasm
d. Ribosomes
e. Golgi body
f. Nucleus

Part 2: Complete the statement with an option.

First sentence:
“The structures within the cytoplasm of eukaryotic cells are ________.”
Options: a. Organelles b. enzymes c. proteins d. fibers
→ Correct answer: a. Organelles — because organelles are the little organs inside the cell, floating in cytoplasm.

Second sentence:
“Cell wastes are digested in organelles called ________.”
Options: a. Golgi bodies b. lysosomes c. vacuole d. ribosomes
→ Correct answer: b. lysosomes — they contain enzymes that break down waste.

Third sentence:
“Water, food, and waste products are stored in the cell’s ________.”
Options: a. vacuoles b. nucleolus c. cell wall d. lysosome
→ Correct answer: a. vacuoles — especially big ones in plant cells store water and nutrients.

Fourth sentence:
“Plant cells differ from animal cells because plant cells have ________.”
Options: a. cell membrane c. nuclear membranes b. cell walls d. endoplasmic reticulum
Wait — options are listed as:
a. cell membrane
c. nuclear membranes
b. cell walls
d. endoplasmic reticulum

But note: both plant and animal cells have cell membranes, nuclear membranes, and ER. Only plant cells have cell walls. So correct answer is b. cell walls.

✔ So Part 2 answers:
1. a. Organelles
2. b. lysosomes
3. a. vacuoles
4. b. cell walls

Part 3: Complete the next image with the labeled parts.

Looking at the diagram, we need to fill in the blank boxes pointing to unlabeled parts.

From top left going clockwise:

Top-left box → points to outer edge of cell → that’s the cell membrane

Right-side box → points to large central structure → that’s the nucleus

Bottom-right box → already labeled “Golgi body” — but wait, there’s another box below it? Let’s check carefully.

Actually, looking again:

There are 5 empty boxes:

1. Top-left → points to outer boundary → cell membrane
2. Right side → points to big round center → nucleus
3. Bottom-right → points to stack near bottom right → already has label “Golgi body”? Wait no — actually, the box is pointing to something else?

Wait — let me re-express based on standard animal cell diagram:

The unlabeled parts likely are:

- One box pointing to the very outer layer → cell membrane
- One box pointing to the big pink circle in middle → nucleus
- One box pointing to small green dots scattered around → those are ribosomes (but some are already labeled)
Wait — in the diagram, “ribosomes” is already labeled on one cluster. But there’s another box pointing to similar dots? Maybe not.

Actually, looking at common labeling:

In many diagrams, the missing labels are:

- Cell membrane (outer edge)
- Nucleus (center)
- Mitochondria (oval with lines inside — there are several, one might be unlabeled)
- Vacuole (small green circles — one may be unlabeled)
- Maybe centrosome? But it’s already labeled.

Wait — let’s count the boxes:

There are 5 orange boxes to fill.

Based on typical textbook diagrams:

Box 1 (top left): points to outer edge → cell membrane

Box 2 (right side): points to large central organelle → nucleus

Box 3 (bottom right): points to oval-shaped organelle with inner folds → mitochondria

Box 4 (bottom left): points to small green circle → vacuole (though one is already labeled, maybe this is another)

Wait — actually, in the diagram, “vacuole” is already labeled on one green circle. There’s another green circle nearby — perhaps that’s also a vacuole? Or maybe it’s a lysosome? But lysosome is already labeled.

Alternatively, maybe one box points to the network near nucleus — but rough and smooth ER are already labeled.

Another possibility: one box points to the purple star-like thing — that’s centrosome, already labeled.

Wait — perhaps I miscounted. Let me list all labeled parts first:

Labeled in diagram:
- lysosome
- nucleolus
- vacuole
- centrosome
- rough endoplasmic reticulum
- smooth endoplasmic reticulum
- ribosomes
- Golgi body

Unlabeled parts that should be filled:

Typically, in such diagrams, the main missing ones are:

- Cell membrane (outer boundary)
- Nucleus (the whole big pink structure — nucleolus is inside it)
- Mitochondria (there are several; if one isn’t labeled, pick one)
- Maybe cytoplasm? But usually not boxed.

Looking at positions:

Top-left box → definitely cell membrane

Right-side box → points to entire central pink area → that’s the nucleus (nucleolus is inside it)

Bottom-right box → points to an oval with internal lines → that’s mitochondria

Bottom-left box → points to a small green circle → since “vacuole” is already labeled on another, this could be another vacuole, or perhaps lysosome — but lysosome is already labeled. Hmm.

Wait — there’s a box pointing to a brownish oval near bottom — that’s likely mitochondria

And another box pointing to a green circle — if vacuole is already labeled, maybe this is just another vacuole? Or perhaps it’s cytoplasm? No.

Actually, in many versions of this diagram, the five blanks are:

1. Cell membrane
2. Nucleus
3. Mitochondria
4. Vacuole (if not all are labeled)
5. Maybe ribosomes? But they’re labeled.

Wait — looking again: there’s a box pointing to the area between organelles — that would be cytoplasm

Yes! Often, one box points to the background gel — that’s cytoplasm.

So let’s assign:

- Box at top-left (pointing to outer edge): cell membrane
- Box at right (pointing to big center): nucleus
- Box at bottom-right (pointing to oval with cristae): mitochondria
- Box at bottom-left (pointing to green circle): vacuole (even if one is labeled, multiple can exist)
- Box at lower middle (pointing to space between organelles): cytoplasm

But in the diagram, is there a box pointing to the background? Yes — one box is pointing to the teal area between organelles — that’s cytoplasm.

Also, one box points to a mitochondrion — yes.

So final assignments for Part 3:

Assuming the boxes are positioned as follows (based on standard layout):

1. Top-left box → cell membrane
2. Right box → nucleus
3. Bottom-right box → mitochondria
4. Bottom-left box → vacuole (or possibly lysosome, but lysosome is labeled — so vacuole is safe)
5. Lower-middle box (pointing to fluid) → cytoplasm

But wait — in the original problem, only 5 boxes? Let me recount from your image description.

You said: “Complete the next image with the labeled parts.” and showed a diagram with 5 orange boxes.

Commonly, in such quizzes, the missing labels are:

- Cell membrane
- Nucleus
- Mitochondria
- Cytoplasm
- And sometimes ribosomes — but they’re labeled.

Alternatively, perhaps one is “centrosome” — but it’s labeled.

I think safest bet based on standard curriculum:

Boxes correspond to:

- Outer boundary → cell membrane
- Central large structure → nucleus
- Oval with inner folds → mitochondria
- Green storage sac → vacuole
- Background jelly → cytoplasm

Yes.

✔ So Part 3 answers (in order of boxes, assuming clockwise from top):

1. Cell membrane
2. Nucleus
3. Mitochondria
4. Cytoplasm
5. Vacuole

*(Note: Depending on exact pointer positions, adjust — but this is standard.)*
