In endocytosis the cell

Options

A. Divides cytoplasm in mitosis
B. Digests itself
C. Engulfs and internalises materials with its membrane
D. Enable extracellular digestion of larger molecules.

Answer

**Step-by-Step Solution:**

1. **Understanding Endocytosis**: Endocytosis is a cellular process where substances are brought into the cell. It involves the cell membrane engulfing material from the external environment.

2. **Mechanism of Endocytosis**: During endocytosis, the cell membrane invaginates (folds inward) to form a pocket around the material. This pocket then pinches off to form a vesicle that carries the material into the cell.

3. **Types of Endocytosis**: There are different types of endocytosis:
- **Phagocytosis**: This is known as "cell eating," where large particles or cells are engulfed.
- **Pinocytosis**: Known as "cell drinking," this involves the uptake of liquid and small solutes.
- **Receptor-mediated endocytosis**: This is a more selective process where specific molecules are taken in after they bind to receptors on the cell surface.

4. **Conclusion**: In summary, during endocytosis, the cell engulfs and internalizes material within its membrane, allowing it to absorb substances from the extracellular environment.

**Final Answer**: In endocytosis, the cell engulfs and internalizes material within its membrane.
