Which structure separates an animal cell from its surrounding environment one nuclear membrane to Golgi apparatus 3 plasma membranes for Central vehicle

Answer 1

The structure that separates an animal cell from its surrounding environment is the plasma membrane (also known as the cell membrane). It is a selectively permeable barrier that controls the movement of substances in and out of the cell, maintaining the internal environment.

Here’s how the other components you mentioned fit into the context:

1. Nuclear membrane: This is a double membrane that surrounds the nucleus, separating it from the cytoplasm. It is not involved in separating the cell from its environment.

2. Golgi apparatus: This organelle is involved in processing, packaging, and modifying proteins and lipids for secretion or use within the cell. It does not serve as a boundary for the cell itself.

3. Central vacuole: This structure is typically found in plant cells (not usually in animal cells) and serves various functions including storage and maintaining turgor pressure. It is surrounded by a membrane called the tonoplast, but again, it is not responsible for separating the cell from the environment.

In summary, the plasma membrane is the main structure that separates the cell from its surrounding environment.
