Biology Vocab Unit 3 Cell and the Cell Membrane

when comparing two solutions, the solution with the greater concentration of solutes

when comparing two solutions, the solution with the lesser concentration of solutes

when the concentration of two solutions is the same

Diffusion of water through a selectively permeable membrane

Movement of molecules from an area of higher concentration to an area of lower concentration.

Photosynthesis

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.

A system of membranes that modifies and packages proteins for export by the cell

Powerhouse of the cell

Found inside the nucleus and produces ribosomes

Control center of the cell

A selectively-permeable phospholipid bilayer forming the boundary of the cells

Makes proteins

Cell organelle that stores materials such as water, salts, proteins, and carbohydrates

A membrane bound sac that contains materials involved in transport of the cell.

A difference in the concentration of a substance across a distance.

water channel protein in a cell

process by which a cell takes material into the cell by infolding of the cell membrane

a property of cell membranes that allows some substances to pass through, while others cannot

Movement of specific molecules across cell membranes through protein channels

the passive movement of molecules along the concentration gradient.

the movement of substances across a cell membrane without the use of energy by the cell

Energy-requiring process that moves material across a cell membrane against a concentration difference

"Cell eating"; an endocytic pathway by which a cell engulfs particles such as microbes or cellular debris.

Process by which a cell releases large amounts of material

Cell drinking
