What is the function of the cell membrane?

Back

The cell membrane is semi-permeable and controls what enters and leaves the cell.

Front

List the phases of mitosis in order.

Back

The phases of mitosis in order are prophase, metaphase, anaphase, and telophase.

Front

What is the purpose of photosynthesis?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose.

Front

What is active transport?

Back

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