Cell Processes Review

Front

What are the reactants of photosynthesis?

Back

Water, sunlight, and carbon dioxide.

Front

What is a hypotonic solution?

Back

A solution whose solute concentration outside of the cell is lower than the solute concentration inside of the cell.

Front

Does the rate of photosynthesis increase if a plant does not have ample sunlight?

Back

FALSE

Front

What is a hypertonic solution?

Back

A solution whose solute concentration outside of the cell is higher than the solute concentration inside of the cell.

Front

What does it mean for a cell membrane to be selectively permeable?

Back

It means the cell membrane is permeable to water, oxygen, and carbon dioxide but not to salts, polar molecules, or large molecules.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs sunlight, allowing plants to convert light energy into chemical energy.

Front

What is osmosis?

Back

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 is the difference between active and passive transport?

Back

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

Front

What is the fluid mosaic model?

Back

A model that describes the structure of cell membranes as a mosaic of various components, including phospholipids, cholesterol, and proteins.
