Unit 2 Test Review Cells

Front

What is Passive Transport?

Back

The movement of particles from an area of higher concentration to an area of lower concentration without the use of energy.

Front

What are Flagella?

Back

Long hair-like projections used for movement in cells, utilizing a whip-like motion.

Front

What are Carcinogens?

Front

Why is mitosis important for multicellular organisms?

Back

Mitosis produces cells that are identical to the original dividing cell, allowing for growth and repair.

Front

What is Active Transport?

Back

The movement of particles against their concentration gradient, requiring energy.

Front

What are Cilia?

Back

Short hair-like structures on the surface of some cells that help in movement and sensing the environment.

Front

What is the Cell Wall?

Back

A rigid outer layer that provides support and protection to plant cells.

Front

What is the Cell Membrane?

Back

A semi-permeable membrane that surrounds the cell, controlling what enters and exits.

Front

What are Kinases?

Back

Enzymes that add phosphate groups to other molecules, often involved in signaling pathways.
