Parts of Cells
| Term | Definition |
|---|---|
| cell membrane | around the outside of cell; holds cell together, lets somethings in and keeps other things out |
| cytoplasm | gel-like fluid inside the cell; holds the cell's organelles |
| nucleus | center of the cell; control centerl: holds information to help the cell run and make new cells (ex. DNA) |
| nuclear membrane | surrounds the nucleus; protects the nucleus |
| vacuoles | clear fluid-filled sacks; stores materials and waste |
| mitochondria | organelle--rod shaped (looks like the bottom of a shoe); uses oxygen to get the energy from food |
| endoplasmic reticulum | organelle (long and thin, passageway like a maze); makes products needed by the cell, makes "deliveries" to other cell parts |
| ribosomes | organelles (tiny and round, grain-like), sometimes attached to the endoplasmic reticulum; makes products needed by the cell |
| golgi bodies | organelles--like stacks of hollow pancakes; "packages" products for delivery |
| chromosomes | threadlike structures found in the nucleus; contains the genes and DNA that determine what a cell and organism does and looks like |
| lysosome | clear sack; breaks down food molecules and waste |
| cell wall | only in plants; outer barrier of the cell, contains cellulose (plant fiber); provides extra support and shape |
| chloroplasts | only in plants; organelle (oval and green), contains chlorophyll (green pigment); chlorophyll captures sunlight, carry out photosynthesis to make food |
