Plant and Animal Cell Organelles
Term | Definition |
---|---|
cell wall | a rigid supporting layer that surrounds the cells of plants and some other organisms |
cell membrane | a thin flexible barrier that surrounds a cell and controls which substances pass into and out of a cell |
nucleus | a large organelle that contains the cell's genetic material in the form of DNA & controls many of the cells activities |
organelle | a tiny cell structure that carries out a specific function within the cell |
ribosome | a small grain shaped organelle in the cytoplasm of a cell that produces proteins |
cytoplasm | the thick fluid region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes) |
mitochondria | rod shaped organelles that convert energy in food molecules to energy the cell can use to carry out its functions |
endoplasmic reticulum | an organelle that forms a maze of passageways in which proteins and other materials are carried from one part of a cell to another |
golgi apparatus | an organelle in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell |
vacuole | a sac-like organelle that stores water, food, and other materials |
chloroplast | an organelle in the cells of plants and some other organisms that captures energy from sunlight and changes to an energy form that cells can use in making food |
lysosome | a cell organelle which contains chemicals that break down large food particles into smaller ones and that can be used by the rest of the cell |
