Cell Concept Term Sheet
Cell- smallest unit and function in a living organism
Cell Membrane- allows materials to enter and leave the cell (acts as the gate keeper)
Nucleus- cell structure that directs all the activities of the cell
Nuclear Membrane- surrounds the nucleus and controls movement of materials into and out of the nucleus
Cytoplasm- living fluid inside the cell membrane
Cell Wall- nonliving layer that surrounds the cell membrane of a plant cell
Chlorplasts- oval-shaped structures that contain(chlorophyll) organic material in green plants that absorbs sunlight for making food
Mitochondria- power house of the cell in the cytoplasm that releases energy from food
Vacuole- large, round-sac in the cytoplasm of the cell that stores water, food, and other materials
Chromosomes- rod-shaped structures that directs all the activities of a cell and passes on the traits of a cell to new cells
Endoplasmic reticulum-maze of passage ways in which proteins and other materials are passed around in the cell
Ribosome-small circular structure in which proteins are made
Lysosome-round structure containing chemicals that break down large food particles into smaller ones
Chromatin-A complex of nucleic acids (DNA or RNA) and proteins, which condenses to form a chromosome during cell division.
Golgi bodies/complex/apparatus- packages molecules like proteins together
