What occurs during cytokinesis in animal cells?
What occurs during cytokinesis in animal cells?
- A cell plate forms that separates the two new cells.
- Chromosomes are duplicated and aligned in the center.
- Cytoplasm and organelles are evenly distributed throughout the cell.
- Cell membrane pinches inward to form two distinct cells. (correct)
Which statement accurately describes the outcome of cytokinesis?
Which statement accurately describes the outcome of cytokinesis?
- Cytokinesis ensures that only one new cell is formed from the parent cell.
- Each new cell receives an unequal amount of cytoplasm.
- Both new cells only retain the cell membrane of the parent cell.
- Both new cells receive approximately half of the original cell's cytoplasm and organelles. (correct)
What structural change is observed in plant cells during cytokinesis?
What structural change is observed in plant cells during cytokinesis?
- A cell plate forms in the center, which eventually becomes the cell wall. (correct)
- The cell membrane strengthens around the edges of each new cell.
- Nucleus divides completely before any other change.
- Cytoplasm flows freely without any structural formation.

Flashcards
Cytokinesis
Cytokinesis
The final stage of cell division where the cytoplasm divides, creating two daughter cells.
Cleavage Furrow
Cleavage Furrow
In animal cells, the cell membrane pinches inward, forming a cleavage furrow that eventually divides the cell into two.
Cell Plate
Cell Plate
In plant cells, a new cell wall forms between the two daughter cells, called a cell plate.

Study Notes
Cytokinesis
- Cytokinesis is a phase of the cell cycle where the cytoplasm divides.
- Each new cell receives about half of the cell's cytoplasm and organelles.
- In animal cells, the cell membrane pinches inward and forms two cells.
- In plant cells, a cell plate forms a midline of the dividing cells.
