Biology EOC Review Set 10

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two daughter cells, each having the same number of chromosomes as the parent cell.

Front

How many chromosomes does a daughter cell have if the parent cell has 24 chromosomes?

Back

24 chromosomes.

Front

What is active transport?

Back

Active transport is the movement of ions or molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to an animal cell in a hypertonic solution?

Back

Water will move out of the cell, causing the cell to shrink.

Front

What is the role of vacuoles in a paramecium?

Back

Vacuoles in a paramecium help to expel excess water that enters the organism.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance across a space.

Front

What phase of mitosis follows metaphase?

Back

Anaphase.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.
