Question | Answer |
cell membrane | the outer layer of a cell |
purpose of cell membrane | to control what goes in and out of the cell |
cytoplasm | the gel-like substance that fills most of the inside of the cell |
nuclear membrane | surrounds the nucleus, controlling what goes in and out of the nucleus |
nucleus | the control center of the cell that contains the genetic material |
organelles | parts of a cell that have specific functions |
cell | the smallest unit of living things |
Cell Theory | the idea that all living things are made of one or more cells and that cells reproduce to make more cells. |
Germ Theory of Disease | the idea that germs (certain microbes) cause diseases |
multicellular | organisms that are made of many parts with different functions that help the whole organism survive |
cellular respiration | the process that all cells do that uses food (sugar) and oxygen to get energy |
carbon dioxide and water | the waste products of cellular respiration |
why we breathe | to get the energy from food (with cellular respiration) |
semipermeable | describes the fact that membranes can let certain things in but stop others |
mitochondria | where much of cell respiration takes place (in eukaryotes), converts energy for the cell |
makes bread rise | yeast respiring and giving off carbon dioxide |
zygote | fertilized cell |
mitosis | cell reproduction in eukaryotes, for growth and repair |
specialization | The process of cells taking on specific shapes and functions, different from many other cells of the same organism. |
differentiation | The differences in cells in an organism. For example, skin cells are very different from nerve cells, which are very different from muscle cells. |
organelles found in plant cells but not animal cells | chloroplasts and cell wall |
advantage of cells being smaller | There is more total surface area, so the cell can absorb more nutrients and oxygen and get rid of wastes more easily. |
"ingredients" for cellular respiration | oxygen and nutrients |
main waste product from cellular respiration | carbon dioxide |
virus | nonliving thing with genetic material that cause illness |
unicellular | organisms that are made of just one cell |
microbe | organisms too small to see without a microscope, could be one cell or more than one cell |
