Here's a breakdown:
* Animal cells: Lack a rigid cell wall. Their outer boundary is a flexible cell membrane. This allows them to:
* Change shape to move around, squeeze through tight spaces, and engulf food.
* Divide and grow in various directions.
* Respond to external stimuli like changes in pressure or light.
* Plant cells: Have a rigid cell wall made of cellulose. This wall provides:
* Structural support and stability, giving plants their upright form.
* Protection from bursting due to internal water pressure (turgor pressure).
* A fixed shape, limiting their ability to move or change form significantly.
Think of it like this: Animal cells are like balloons, able to inflate and deflate and take different shapes. Plant cells are like boxes, sturdy and maintaining a consistent form.
While plant cells can't drastically change shape, they can grow and develop in specific ways thanks to the cell wall's structure. This allows plants to grow taller, wider, and develop unique shapes based on their specific needs.
