Cell Biology flash cards

Front

Active transport

Back

The movement of substances from a more dilute solution to a more concentrated solution (against a concentration gradient) with the use of energy from respiration.

Front

Adult stem cell

Back

A type of stem cell that can form many types of cells.

Front

Agar jelly

Back

A substance placed in petri dishes which is used to culture microorganisms on.

Front

Back

An outer layer made of cellulose that strengthens plant cells.

Front

Chloroplast

An organelle which is the site of photosynthesis.

Front

Chromosomes

Back

DNA structures that are found in the nucleus which are made up of genes.

Front

Concentration gradient

Back

The difference in concentration between two areas.

Front

Diffusion

Back

The spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration.
