| Question | Answer |
|---|---|
| What happens to a cell once it reaches it limit? | Either stops growing or divides |
| The key factor that limits the size of a cell is the ration of its ____ to its____ | Surface Area to Volume |
| Is the size of a cell large or small beneficial to a cell? Why? | Small, because cells have higher ratio of surface area to volume and can sustain themselves more easily |
| Which task is more difficult in a larger cell than a smaller cell? | Movement of Substances |
| Cells reproduce by a cycle of growing and dividing called the _______. | Cell Cycle |
| What are the three main stages of the Cell Cycle? | Interphase, Mitosis, and Cytokinesis |
| Cytokinesis is the method by which a cell's ____ divides, creating a new cell. | Cytoplasm |
| Interphase is divided into what three stages? | G1, (Gap1), S(synthesis), G2(Gap2) |
| What is the relaxed form of DNA in the cell's nucleus called? | Chromatin |
| In Cytokinesis, cell divides into two _____ cells with identical ___. | Daughter cells with identical nuclei |
| True or False: As the Cell grows, its volume increases much more rapidly than the surface area. | True |
| The protein that makes microtubules for cell division is synthesized in what stage of interphase? | 3rd stage of interphase |
| What happens in the second stage of interphase? | Period when cell copies its DNA in preparation of cell division |
| True or False: Chromatin is the structure that contains genetic material that is passed from generation to generation. | False, Chromosomes |
| What happens in the third stage of interphase? | Period when cell prepares for the division of its nucleus |
| During the first stage of interphase, a cell is growing, carrying out normal cell functions, and preparing to ________ ____. | Replicate DNA |
| Mitosis is the stage of the cell cycle during which the cell's ______ and _____ material _______. | Cell's nucleus and nuclear material divide |
| Give an example where a larger cell has a disadvantage | Signals that trigger protein synthesis might not reach the ribosome fast enough for protein synthesis to occur to sustain the cell |
| Why is diffusion over large substances slow and inefficient? | because it relies on random movements of molecules and ions |
| The Volume of a cell refers to the space taken up by the inner contents of the cell, including organelles in the _______ and ________. | Cytoplasm and Nucleus |
| The Surface area of a cell refers to the area covered by __________. | Plasma Membrane |
