Cell Transport

Front

What is pinocytosis?

Back

Pinocytosis is a form of endocytosis where a cell engulfs liquid, often referred to as 'cell drinking.'

Front

What does equilibrium mean in the context of cell transport?

Back

Equilibrium refers to a state where molecular movement continues, but there is no overall change in concentration inside and outside the cell.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on the kinetic energy of the molecules.

Front

What does it mean for a solution to be isotonic?

Back

A solution is isotonic when the concentration of solutes is the same inside and outside the cell, resulting in no net movement of water.

Front

What is phagocytosis?

Back

Phagocytosis is a type of endocytosis where a cell engulfs large particles or other cells, often referred to as 'cell eating.'

Front

What is the difference between active transport and passive transport?

Back

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

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 exit 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 enter the cell.

Front

What role does the cell membrane play in transport?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is osmosis?

Back

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