Let’s solve this step by step.
First, look at the diagram of the plant cell. It shows many labeled parts like chloroplast, mitochondrion, ribosome, vacuole, nucleus, cell wall, etc. The word bank gives us these same terms to use for labeling — but some are already labeled in the diagram (like smooth endoplasmic reticulum, Golgi apparatus, rough endoplasmic reticulum, cell membrane). So we need to label the unlabeled structures using the remaining words from the word bank:
- cell wall
- chloroplast
- mitochondrion
- ribosome
- vacuole
Looking at the diagram:
- The large central space is the
vacuole — it’s big and takes up most of the center.
- The green oval-shaped structures with internal lines are
chloroplasts — they’re where photosynthesis happens.
- The small dots scattered around (especially on the rough ER) are
ribosomes.
- The bean-shaped organelles with inner folds are
mitochondria (singular: mitochondrion).
- The outermost rigid layer surrounding the whole cell is the
cell wall.
Now, answer question 1:
“Which structure is found in a plant cell but not in an animal cell? Circle the correct answer.”
Options: chloroplast, cell membrane, ribosome
We know:
- Cell membrane → both plant and animal cells have it.
- Ribosome → both have them too (they make proteins).
- Chloroplast → ONLY plant cells have them (for making food via sunlight).
So the correct answer is
chloroplast.
Question 2: “What is the main function of vacuoles?”
In plant cells, the large central vacuole stores water, nutrients, and waste. It also helps keep the cell firm (turgor pressure). But the main function taught at this level is usually:
to store water and other materials.
Final Answer:
1. chloroplast
2. To store water and other materials (or simply: storage)
