Facilitated Diffusion
Which term is used to define the series of changes that cell undergoes, from the time It forms until it divides?
Cell cycle
What occurs during cytokinesis?
The cytoplasm is divided between the cells
Within the cytoplasm, what is the clear liquid in which organelles are suspended?

Ribosome
What is the term given to the difference in concentration of particles from one area to another?
Gradient
Which cell structure acts as a selectively permeable barrier, controlling the movement of substances into and out of the cell?
The plasma membrane
Organelles that are composed of protein and RNA and are the sites of protein synthesis are called ________.
