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 |
