Questions and Answers
What is divided during cytokinesis?
The cell's cytoplasm is divided between the daughter cells.
How does cytokinesis occur in an animal cell?
A cleavage furrow forms and the cytoplasm is pinched in two.

Study Notes
Cytokinesis Overview
- Cytokinesis is the process dividing the cytoplasm between daughter cells after mitosis or meiosis.
- The outcome of cytokinesis is the formation of two distinct daughter cells.
Cytokinesis in Animal Cells
- In animal cells, cytokinesis occurs through the formation of a cleavage furrow.
- The cleavage furrow develops as the cytoplasm is pinched, ultimately splitting the cell in two.
Cytokinesis in Plant Cells
- Plant cells utilize a different method, forming cell plates between the two new cells.
- These cell plates eventually develop into cell walls, facilitating the separation of daughter cells.
Cytokinesis after Mitosis
- Mitosis can occur in cells that may have multiple nuclei.
- Some of these cells may skip the cytokinesis step, resulting in cells with more than one nucleus.
Cytokinesis and Meiosis
- Not every cell undergoing meiosis completes cytokinesis in a manner that evenly divides the cytoplasm.
- An example of unequal cytoplasmic division following meiosis is observed in human female gamete production.
