Cell Definitions

The movement of molecules from an area of high concentration to low concentration

the movement of water through a semi-permeable membrane

• regulates what goes in and out of the cell - holds the cell together

• the storage area of the cell - it contains water and some other substances

• the powerhouse of the cell - makes energy in the form of ATP (Adenosi triphosphate)

• double membrane, found in plants - contains chlorophyll for photosynthesis

• the “stomach” of the cell - contains enzymes, helps to digest food and break down old cells

• elaborately folded network of tubules • involved in transportation of substances • contains ribosomes (beads)

assemble proteins for growth and repair

brain of the cell • controls all acitivities of the cell • reproduction of the cell (heredity)

DNA

packages substances for transport - creates vesicles

fluid part of the cell
