| Question | Answer |
|---|---|
| Centrioles are found in both plant and animal cells. True or False? | FALSE – ONLY ANIMALS HAVE THEM. |
| In what stage of mitosis can you see chromosomes (where the nuclear membrane has broken down) and they are condensed in the middle of the cell? | Prophase |
| In what stage of the cell cycle does the DNA replicate? | S Phase |
| In what stage of mitosis are the chromosomes being pulled apart by spindle fibers? | Anaphase |
| What would happen if a cell skipped over the “S Phase” ? | The cell would have too little DNA when mitosis begins |
| In what stage of Mitosis does the cell look like a normal cell, nucleus is intact and no mitotic activities are happening? | Interphase |
| What is the correct order of the 3 sub phases of interphase? | G1 → S → G2 |
| In what stage of Mitosis have the two separate nuclei re-formed; it is still one cell? | telophase |
| How does cancer come about in someone’s body? | Imperfect cells will grow unchecked and divide, rather than going through apoptosis at those missed checkpoints. |
| In what stage of the Mitosis are the Chromosomes lined up in the middle of the cell? | Metaphase |
| What is cytokinesis? | Splitting of the cytoplasm. |
| What happens with plant cells in the cytokinesis process? | Cell plate forms |
| What happens with animal cells in the cytokinesis process? | Cleavage furrow |
| Which type of cells divide infrequently? Brain or skin? | Brain cells |
| Which type of cells divide frequently? Brain or skin? | skin cells |
| Cell division in prokaryotes is known as... | Binary fission |
| What are the structures that contain DNA called? | Chromosomes |
| When cells are damaged, they undergo what process known as a planned cell death? | Apoptosis |
