Question

not present in animal cells?

Answer 1

Animal cells lack certain structures that are found in plant cells. Here are a few key components that are not present in animal cells:

1. **Cell Wall**: Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection. Animal cells have only a flexible plasma membrane.

2. **Chloroplasts**: These organelles are responsible for photosynthesis in plant cells. Animal cells do not have chloroplasts because they do not perform photosynthesis.

3. **Large Central Vacuole**: Plant cells typically have a large central vacuole that stores water and nutrients, and helps maintain turgor pressure. While animal cells do have small vacuoles, they are not as prominent as in plant cells.

4. **Plasmodesmata**: These are channels between plant cells that allow for communication and transport of materials. Animal cells communicate through different mechanisms and lack plasmodesmata.

These differences highlight the distinct roles and functions of plant and animal cells in their respective organisms.
