Explanation:
The given statement is false. Animal cells do not have a rigid cell wall like plant cells. Instead, animal cells are surrounded by a flexible cell membrane that provides shape and protection to the cell. Here is a detailed explanation:
Differences between plant and animal cells:
1. Cell wall:
- Plant cells have a rigid cell wall composed of cellulose, which provides structural support to the plant.
- Animal cells do not have a cell wall; instead, they have a flexible cell membrane made up of lipids and proteins.
2. Shape:
- Plant cells have a fixed shape due to the rigid cell wall, which maintains the structural integrity of the cell.
- Animal cells have a variable shape and can change their shape as needed. The absence of a cell wall allows them to be more flexible.
3. Function:
- The cell wall in plant cells provides mechanical support, protection, and helps to maintain turgor pressure.
- The cell membrane in animal cells regulates the movement of substances in and out of the cell, and also plays a role in cell signaling and recognition.
4. Permeability:
- The cell wall in plant cells is porous and allows the passage of water, ions, and other molecules.
- The cell membrane in animal cells is selectively permeable, controlling the movement of substances and maintaining the internal environment of the cell.
In conclusion, animal cells do not have a rigid cell wall like plant cells. They are surrounded by a flexible cell membrane that provides shape and protection to the cell.
