Q1. What happens during Endocytosis?

Background

Topic: Eukaryotic Cell Processes

This question is testing your understanding of how cells take in substances from their environment using endocytosis.

Key Terms:

• Endocytosis: The process by which cells engulf external material by wrapping their membrane around it.

• Vesicle: A small membrane-bound compartment formed during endocytosis.

Step-by-Step Guidance

1. Consider how the cell membrane interacts with external particles or fluids.

2. Think about the formation of a pocket or indentation in the membrane.

3. Recall what happens to the pocket as it deepens and eventually pinches off inside the cell.

4. Reflect on the fate of the vesicle and its contents once inside the cell.
