Question

1. made of proteins. provides structural support for animal cells
2. covered with ribosomes and surrounding the nucleus.
3. where photosynthesis occurs.
4. made of microtubules. help the cell divide by pulling chromosomes apart.
5. made of cellulose in plants, chitin in fungi, and peptidoglycan in bacteria.
6. transport proteins around the cell

Explanation:

1. The cytoskeleton in animal cells is made of proteins and provides structural support.
2. The rough endoplasmic reticulum is covered with ribosomes and is often near the nucleus.
3. Chloroplasts are the organelles where photosynthesis occurs.
4. Spindle fibers, made of microtubules, help in cell - division by pulling chromosomes apart.
5. Cell walls are made of cellulose in plants, chitin in fungi, and peptidoglycan in bacteria.
6. Vesicles transport proteins around the cell.
