BIO - EOC Prep: Cell Transport

Front

What happens to a plant cell when placed in salt water?

Back

The plant cell will shrivel because water diffuses out of the cell.

Front

What is the movement of particles from an area of high concentration to an area of low concentration called?

Back

Diffusion.

Front

In passive transport, molecules move from an area of __________ concentration to an area of __________ concentration.

Back

High concentration to low concentration.

Front

What do all living things strive to maintain?

Back

Homeostasis.

Front

What is the process called when cells surround and engulf substances that are too big to enter the cell?

Back

Endocytosis.

Front

Define osmosis.

Back

The movement of water molecules across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves molecules from high to low concentration, while active transport requires energy and moves molecules from low to high concentration.

Front

What is plasmolysis?

Back

The process in which cells lose water in a hypertonic solution, causing the cell membrane to pull away from the cell wall.

Front

What is the role of the cell membrane in transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
