In the situation described in question 8, would water move into or out of the cell? 10. Which part of the cell produces proteins by assembling amino acids? A. Chloroplast B. Lysosome C. Ribosome D. Proteosome _________ 11. List two structures that a plant cell has, and that an animal cell does not. 12. If water moves into a plant cell, will the cell explode? Why or why not? 13. What is the function of the Nucleolus? 14. Many organisms live in the ocean, which is salt water. Thus, you would think that water would tend to move out of the cells of these organisms, because the salt water is hypertonic to their cells. This is not true. Propose one idea for how these organisms prevent their cells from loosing all their water and shriveling up.
