Cell Membrane & Transport Flashcard (CP)

Front

What is Exocytosis?

Back

Exocytosis is the process by which cells use energy to transport large particles out of the cell by vesicles that fuse with the cell membrane.

Front

What happens to a plant cell in a hypertonic solution?

Back

In a hypertonic solution, a plant cell loses water to the environment, leading to plasmolysis, where the cell shrinks away from the cell wall.

Front

Define Facilitated Diffusion.

Back

Facilitated diffusion is a passive transport process that allows large or polar molecules to cross the cell membrane with the help of transport proteins.

Front

What is Endocytosis?

Back

Endocytosis is the process by which cells engulf large particles or molecules by enclosing them in a membrane vesicle to bring them into the cell.

Front

What is a Hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is a Hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What is Isotonic solution?

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What occurs during Plasmolysis?

Back

Plasmolysis occurs when a plant cell loses water in a hypertonic environment, causing the cell membrane to pull away from the cell wall.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What is Osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
