What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy. It relies on concentration gradients.

Front

Who is known for the principle that all cells come from other living cells?

Back

Rudolf Virchow is known for this principle, which is a key part of cell theory.

Front

What is diffusion?

Back

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

Front

Which transfer is the most energy efficient for a hawk?

Back

The most energy efficient transfer for a hawk is shrubs → mice → hawks.

Front

What are lipids?

Back

Lipids are a group of organic compounds that include waxes, oils, and fats, which are insoluble in water.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the cell theory?

Back

The cell theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells come from pre-existing cells.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem.

Front

What are carbohydrates?

Back
