Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

Which factors affect the rate of diffusion?

Back

Temperature, concentration gradient, and surface area affect the rate of diffusion.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles responsible for photosynthesis, converting sunlight into energy.

Front

What is homeostasis?

Back

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

Front

What happens to a cell in a hypotonic solution?

Back

A cell in a hypotonic solution will swell as water enters the cell.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher concentration of solutes compared to the cell, while hypotonic solutions have a lower concentration.

Front

What is the function of mitochondria?

Back

Mitochondria are organelles that produce energy (ATP) through cellular respiration.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.

Front

What is the significance of surface area in diffusion?

Back

A larger surface area allows for more molecules to diffuse across a membrane at once.
