✂️ Cytokinesis: Dividing the Cytoplasm
After nuclear division (mitosis), the cytoplasm must also divide to create two separate cells. This process differs between plant and animal cells:
🐾 Animal Cells
- Cell membrane pinches inward from opposite sides
- Forms a cleavage furrow that deepens
- Contractile ring of proteins squeezes the cell
- Eventually pinches completely to form two cells
- Process is like squeezing a balloon in the middle
🌱 Plant Cells
- Cell wall prevents pinching like in animals
- New cell wall forms from inside out
- Cell plate grows outward from center
- Cell plate eventually meets existing cell wall
- Two new cells with complete cell walls formed
