Vocabulary #4 & #5
Cell parts/organelles, and cell division
| Question | Answer |
|---|---|
| cell (#4) | basic unit of structure and function in living things |
| nucleus (#4) | found in Eukaryotic cells. Controls all cell activities. |
| cell membrane (#4) | a thin "skin" that surrounds the cell and controls what goes in and out of the cell |
| mitochondria (#4) | organelles that turn food into energy through cell respiration |
| organelle (#4) | a part inside a cell that has its own membrane and does its own special job to keep the cell alive |
| ribosome (#4) | a tiny part inside a cell that produces proteins |
| endoplasmic reticulum (ER) (#4) | an organelle that is a network of pathways that move materials throughout the inside of a cell |
| cytoplasm (#4) | the watery liquid that fills up the cell and keeps the organelles floating inside it |
| vacuole (#4) | an organelle that is used to store water, food or other materials |
| organism (#4) | a single living thing |
| chloroplast (#5) | a green organelle in plants that uses sunlight to make food (sugar) through the process of photosynthesis |
| cell wall (#5) | a tough structure on the outside of plant cells that protects and supports the cell |
| chlorophyll (#5) | the green chemical inside chloroplasts that absorbs sunlight. |
| lysosome (#5) | an organelle that contains chemicals that break down waste materials and food into smaller pieces. |
| mitosis (#5) | a type of cell division: a cell divides into two exact copies of itself. The new "daughter" cells have the same number of chromosomes as the "parent" cell. |
| meiosis (#5) | a special type of cell division used only to create sex cells in the reproductive organs. The parent cell divides into four different "daughter" cells that each have only half the number of chromosomes as the parent cell. |
| chromosome (#5) | a structure found inside the nucleus of eukaryotic cells that is made of DNA |
| somatic cell (#5) | a body cell - not used for sexual reproduction |
| gamete (#5) | a sex cell - only used for sexual reproduction |
| cell cycle (#5) | a series of repeating phases (stages) during a cell's life that includes periods of growth, replication, and division. |
