| Question | Answer |
|---|---|
| prokaryote | a unicellular organism that lacks a nucleus and membrane bound organelles |
| eukaryote | a cell that contains a nucleus and membrane bound organelles |
| plant cells | square shaped cell that contains cell wall and chloroplast and contains one large vacuole |
| animal cells | round shape cell that contains a cell membrane, nucleus, and small vacuole |
| organelle | a tiny cell structure that carries out a specific function within the cell |
| nucleus | in cells, a large oval organelle that contains the cell genetic material in the form of dna and controls many of the cell activites "control center" |
| nucleolus | a region found within the cell nucleus that is concerned with producing and assembling the cell's ribsome |
| cytoplasm | the thick jelly like fluid region of a cell that holds the organelles |
| smooth er | simliar to rough er. without ribosomes. involved with synthesizing, modifying packing lipids, steroid and phospholipids |
| rough er | studded with ribosomes produces and packages proteins located near the nucleus |
| ribosomes | synthesizes protein |
| mitochondria | rod shaped organelles that convent energy in food molecules to energy the cell can use to carry out its function ''power house of the cell' |
| chloroplast | an organelle in the cell of plants and some other organisms that capture energy from sunlight and changes to an energy from that cells can use in making food |
| lysosome | found mainly in animal cells, disgest and old cell parts |
| cell membrane | an organelle in both plant and animal cells that separates the inside of the cell from the outside environment |
