| Question | Answer |
|---|---|
| Cell membrane | the outer boundary of the cell that helps control the substances that enter or exit a cell |
| Cell wall | a rigid structure that surrounds, protects and gives shape to plant cells |
| Chloroplast | a cell part that converts light energy from the sun into energy in plants |
| Cytoplasm | a jellylike material found between the cell membrane and the nucleus of a cell; contains most of the cell's internal parts |
| Nucleus | the "brain" or control center of the cell that stores inherited information |
| Mitosis | is the form of cell division that produces identical copies of the parent cell. In multicellular organisms, new tissue is built through countless mitotic cell divisions |
| organelles | Cells consist of smaller pieces |
| endoplasmic reticulum | transports chemicals between and within cells |
| Meiosis | is the form of cell division by which unique gametes (sex cells) are produced. A gamete--either an egg or a sperm cell--combines with a gamete of another individual to produce a unique offspring through sexual reproduction |
| CELL THEORY | •the cell is the basic building block in all living things |
| CELL THEORY | •all organisms are made up of one or more cells |
| CELL THEORY | •cells arise from other cells through cellular division called mitosis |
| CELL THEORY | •all cells are essentially the same in chemical composition |
| CELL THEORY | •energy flow (metabolism) occurs within cells |
| “basic building blocks | Cells |
| multi-cellular | dependent on other cells for their survival |
| single-celled | and contain all the components necessary for its own survival. |
| vacuole | stores water and ingested food in a fluid sack |
| endoplasmic reticulum | transports chemicals between and within cells. |
