Cell Theory | All living things are composed of cells Cells are the basic units of structure and function in living things. All cells are produced by other cells |
Organelles | A tiny cell structure that carries out specific functions within the cell. |
Cell Wall | A rigid layer of nonliving material that surrounds the cells of plants and some other organisms. |
Cell Membrane | A cell structure that controls which substances can enter or leave the cell. Protects the inside from the outside. |
Vacuole | A sac inside a cell that acts like a storage area. |
Chloroplast | A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food. |
Cytoplasm | The region between the cell membrane and the nucleus; in organisms without a nucleus, the region is located inside the cell membrane. |
Mitochondira | Rod-shaped cell structures that convert energy in food molecules into energy the cell can use to carry out its functions. |
Nucleus | A cell structure that contains nucleic acids, the chemical instructions that direct all the cell’s activities |
Endoplasmic Reticulum | A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another. |
Golgi Body | A structure 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. |
Lysosome | A small, round structure containing chemicals that break down large food particles into smaller ones. |
Ribosome | A small grain-like structure in the cytoplasm of a cell where proteins are made |
Prokaryotic | Bacteria Cells / No Nucleus |
Eukaryotic | Plant or Animal Cells / Has a Nucleus |
