Front

What is the plasma membrane?

Back

The plasma membrane is a biological membrane that separates and protects the interior of all cells from the external environment.

Front

Define passive transport.

Back

Passive transport is the movement of substances across a cell membrane without the need for energy input, relying on concentration gradients.

Front

What is diffusion?

Back

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

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the plasma membrane.

Front

What are abiotic factors?

Back

Abiotic factors are the nonliving components of an ecosystem, such as sunlight, water, temperature, and minerals.

Front

What are biotic factors?

Back

Biotic factors are the living components of an ecosystem, including plants, animals, and microorganisms.

Front

What is equilibrium in the context of cells?

Back

Equilibrium occurs when the concentrations of water and solutes are equal inside and outside of a cell, resulting in no net movement of water.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: Water + Carbon dioxide + Sunlight = Glucose + Oxygen.
