Question

for description below, determine if it applies to cell division in animal cells (a), plant cells (p), or both (b). 15. __ centrioles are present. 16. the mitotic spindle is present. 17. a preprophase band appears temporarily before prophase. 18. sister chromatids separate during anaphase. 19. during telophase, a cleavage furrow forms which will later assist the cell in dividing. 20. during interphase, the cell spends its time growing. 21. during telophase, a cell plate forms between the nuclei which eventually divides the cell into two. 22. __ during prophase the nuclear envelope breaks down.

Explanation:

1. Centrioles are organelles found in animal cells and are not present in plant cells.
2. The mitotic spindle forms in both animal and plant cells during cell - division to separate chromosomes.
3. A preprophase band is a plant - cell specific structure that appears before prophase.
4. Sister chromatid separation during anaphase occurs in both animal and plant cells.
5. A cleavage furrow forms during telophase in animal cells to divide the cell.
6. During interphase, both animal and plant cells grow, carry out normal metabolic functions, and replicate DNA.
7. A cell plate forms during telophase in plant cells to divide the cell into two.
8. The nuclear envelope breaks down during prophase in both animal and plant cells.
