| thin flexible barrier that regulates what enters and exits the cell; composed of two layers of lipids | ||
| membrane surrounding the nucleus | ||
| contains the DNA and controls all of the cell's acitivities | ||
| helps to assemble ribosomes | ||
| material between the cell membrane and the nucleus | ||
| breaks down food to make ATP | ||
| internal transport system of the cell, modifies proteins, and synthesizes lipids | ||
| stack of membranes that modify proteins and creates "packages" to send them to other locations | ||
| filled with enzymes to breakdown dead cell parts and foreign objects; only found in animal cells | ||
| synthesizes proteins | ||
| stores water and nutrients for the cell; very large in plant cells | ||
| provides structure and support around cell membrane of plants, fungi, and some bacteria | ||
| uses sunlight to make carbohydrates in plants, some bacteria and protists | ||
| organize the spindle fibers to separate chromosomes during animal cell mitosis | ||
| network of proteins in the cytoplasm that help cell maintain its shape | ||
| hairlike projections that help some cells move | ||
| whiplike structure some cells use for propulsion | ||
| projection of cytoplasm that some protists use for movement and feeding | ||
| cell without a nucleus, it contains a cell membrane, cytoplasm, and ribosomes; bacteria | ||
| cell with a nucleus and membrane bound organelles; animals, plants, protists, fungi |
