| Question | Answer |
|---|---|
| organelles | -tiny cell structure -produces energy,builds and transports needed materials, and recycled waste |
| cell wall | a rigid layer of non living material that surrounds the cells of PLANTS and some other organims |
| cell membrane | the outside boundary of a cell;controls which substances can enter or leave the cell |
| nucleus | -a large, ovalstructure that acts as the brain -cell's control center , directing all of the cell's activities |
| chromatin | material in cells that contains that contains DNA and carries genetic information |
| nucleolus | where ribosomes are made |
| cytoplasm | the region between the cell membrane and the nucleus |
| mitochondria | rod shaped cell structures that produce most of the energy needed to carry out the cell's functions |
| endoplasmic reticulum | a cell structure that forms passageways in which proteins and other maerials are carried from one part of the cell to another |
| ribosome | small grainlike bodies that produce proteins |
| Golgi bodies | a structure in a cell that recieves proteins and other newly formed materials form the endoplasmic reticulum, packages them, and distributes them to other parts of the cell |
| chloroplasts | a structure in the cells of plants and organisms that captures energy from sunlight and uses it to produce food |
| vacules | a water-filled sack inside a cellthat acts as a storage area |
| lysosomes | a small round cell structure that contains chemicals that break down large food particles into smaller ones |
| prokaryotes | organisms whose cells lack a nucleus |
| eukaryotes | organisms whose cells contain a nucleus and many organelles |
