Front

What part of a phospholipid is hydrophilic?

Back

The phosphate head is hydrophilic.

Front

What is required for all types of active transport?

Back

It requires energy.

Front

What type of transport does not require energy?

Back

Passive Transport.

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.

Front

Which cell part is NOT found in plant cells?

Back

Centrioles.

Front

What is the function of chloroplasts?

Back

Chloroplasts are responsible for photosynthesis in plant cells.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of transporting molecules across a cell membrane via protein channels without energy.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.

Front

What role do vesicles play in active transport?

Back

Vesicles transport molecules across the cell membrane during active transport.
