Plasma Membrane and Cellular Transport

Front

What does the prefix/suffix 'philic' mean?

Back

'Philic' means 'love', often used in terms like hydrophilic (water-loving).

Front

What type of solution is a blood cell in if it shrinks?

Back

The blood cell is in a hypertonic solution.

Front

What is endocytosis?

Back

Endocytosis is an active transport process where a cell engulfs material from the outside environment.

Front

What is pinocytosis?

Back

Pinocytosis is a type of endocytosis where a cell 'drinks' fluid by engulfing it in vesicles.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a passive transport process that uses proteins to help move substances across the plasma membrane.

Front

What does 'hypertonic' mean in relation to cells?

Back

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

Front

What does 'hypotonic' mean in relation to cells?

Back

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

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 osmosis?

Back

Osmosis is the passive movement of water across a selectively permeable membrane from an area of low solute concentration to high solute concentration.

Front

What is a vesicle?

Back

A vesicle is a small membrane-bound sac that transports materials within a cell.
