Science
| Term | Definition |
|---|---|
| Animal Cell | A cell that is in animals |
| Plant Cell | A cell in all plants |
| Bacteria Cell | A cell that makes up a bacteria |
| Mitochondrion | spherical to rod-shaped organelles with a double membrane. |
| Ribosome | Pockets of Protein |
| Vesicle | Something holding liquid |
| Nucleus | spherical body containing many organelles, including the nucleolus |
| Chloroplast | Membrane-bound organelles that use light energy and make food. |
| Golgi Apparatus | a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus |
| Cell Membrane | A flexible covering that protects the inside of a cell from the environment outside the shell. |
| Cell wall | A stiff structure the cell membrane that protects a cell from attack by viruses and other harmful organisms. |
| Cytoskeleton | A network of threadlike proteins joined together that gives a cell it's shape and helps it move. |
| Smooth Endoplasmic Reticulum | a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm |
| Rough Endoplasmic Reticulum | a vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm |
| Lysosomes | (also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place. |
| Centriole | A organelle near the nucleus in a animal cell |
| DNA | A substance that carries genetic information in the cells of plants and animals. |
| Flagellum | These are long, tail like things that move back and forth making the cell move. |
| Prokaryotic Cell | In this type of cell there is not a membrane. |
| Eukaryotic Cell | Plants, animals, fungi, protists are made of this. |
| Organelles | This is surrounded by membranes. Every Eukaryotic Cell has other structures and this is one of them. This one has special functions. |
| Multicellular | Having many cells |
| Nuclear Membrane | the membrane that surrounds the nucleus |
| Nuclear Envelope | This contains a lot of pores. |
| Nucleolus | A small structure in the nucleus of a cell |
| Unicellular | Having only one cell |
| Cell Theory | the theory that cells form the fundamental structural and functional units of all living organisms; proposed in 1838 by Matthias Schleiden and by Theodor Schwann |
