Question

1. most animals have internal or external skeletons for structure and support. which of the following parts provide a similar function in plant cells? a. cytoplasm b. chloroplasts c. cell membranes d. cell walls

Explanation:

• Cytoplasm: It is the jelly - like substance inside the cell where organelles are suspended. It does not provide structural support like a skeleton.
• Chloroplasts: These are involved in photosynthesis (converting light energy into chemical energy). They have no role in structural support.
• Cell membranes: They are semi - permeable membranes that control the movement of substances in and out of the cell. They do not provide the same level of structural support as a skeleton.
• Cell walls: In plant cells, the cell wall is a rigid structure made of cellulose. It provides structural support and protection to the plant cell, similar to how internal or external skeletons provide structure and support in animals.

Answer:

D. cell walls
