Here's a breakdown:
* Plant cells have a rigid cell wall made of cellulose that surrounds the cell membrane. This provides structural support and protection, giving the plant its shape and allowing it to withstand turgor pressure.
* Animal cells lack this rigid cell wall and instead have a flexible cell membrane.
This difference is important for several reasons:
* Shape: Plant cells have a more defined, rectangular shape due to the cell wall, while animal cells are more flexible and can adopt various shapes.
* Growth: Plant cells grow by increasing the size of their vacuoles and expanding the cell wall. Animal cells grow by increasing the number of cells through cell division.
* Turgor Pressure: The cell wall allows plant cells to maintain a high internal pressure called turgor pressure, which helps the plant stand upright and transport water. Animal cells do not experience turgor pressure to the same extent.
While the cell wall is a major difference, there are other distinctions between plant and animal cells, including the presence of chloroplasts (for photosynthesis) in plants and the absence of lysosomes in some plant cells.
