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 |
