Mitosis Worksheet & Diagram Identification

1. Chromosomes move to the middle of the spindle during what phase? Metaphase 2. What are sister chromatids? When do the separate? Sister Chromatids are identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. The Sister Chromatids are separated during Anaphase. 3. During which phase do chromosomes first become visible? Prophase 4. In multicellular organisms, the cell cycle produces groups of cells that perform the same function. What are these groups of cells called? These groups of cells are called tissues. Complete the table by checking the correct column for each statement. Statement 5. Cell growth occurs

The following are not in the correct order. Please answer the questions below.

13. Which cell is in metaphase? Cell C is currently undergoing Mitosis. 14. Cells A and F show an early and late stage of the same phase of mitosis. What phase is it? The phase is known as Prophase. 15. In cell A, what is the structure labeled X? The centrioles or centrosomes are labeled by X. 16. In cell F, what is the structure labeled Y? The spindle fibers or microtubules are Y. 17. Which cell is not in a phase of mitosis? Cell D is not a phase in Mitosis. 18. What two main changes are taking place in cell B? In Cell B, there is a cleavage furrow as well as the nucleus reforming, with the DNA uncoiling, as well. 19. Sequence the six diagrams in order from first to last. In order: D – A – F – C – E - B 20. What is the end product of mitosis? Two identical daughter cells are the end products. 21. What is the main difference between cytokinesis in plants and animals? Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughter cells. In plants, this occurs when a cell wall forms in between the daughter cells. In animals, this occurs when a cleavage furrow forms.
