Diffusion, Osmosis, and Active Transport

Front

Factors affecting the rate of diffusion.

Back

Factors include temperature, concentration gradient, surface area, and the nature of the medium.

Front

Importance of osmosis in plants.

Back

Osmosis helps maintain cell turgor, which is essential for plant structure and nutrient absorption.

Front

Importance of active transport in plants.

Back

Active transport allows plants to absorb minerals from the soil against a concentration gradient.

Front

Define diffusion

Back

Net movement of particles from a region of higher concentration to a region of lower concentration

Front

Energy required for diffusion?

Back

No energy is required for diffusion

Front

Energy required for osmosis?

Back

No energy is required for osmosis

Front

What happens when equilibrium is reached?

Back

Eventually, there will be equal concentrations of particles on both sides of the membrane, and there will be NO NET movement of particles.
