Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration.

Front

What happens to water during osmosis?

Back

Water moves from high to low concentration.

Front

What is the percentage of energy available to the next trophic level in an ecosystem?

Back

10% of energy is available to be passed on to the next trophic level.

Front

What is the term for a solution that has a lower concentration of solutes compared to the inside of a cell?

Back

Hypotonic solution.

Front

What is homeostasis?

Back

Homeostasis is the process of maintaining a stable internal environment in an organism.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy for photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the primary function of photosynthesis?

Back

The primary function of photosynthesis is to convert light energy into chemical energy in the form of glucose.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
