Cell Transport

Front

What is a hypotonic environment?

Back

A hypotonic environment is when the percentage of water is higher outside the cell than inside the cell, causing too much water to enter the cell, which may lead to the cell bursting.

Front

In passive transport, substances move across the cell membrane ________ the concentration gradient.

Back

In passive transport, substances move across the cell membrane WITH the concentration gradient.

Front

What are the two types of cell transport?

Back

The two types of cell transport are Passive and Active transport.

Front

What is required for the movement of materials from an area of low concentration to an area of high concentration?

Back

The movement from low to high concentration requires energy (ATP).

Front

What is a hypertonic environment?

Back

A hypertonic environment is when the percentage of water is lower outside the cell than inside the cell, causing too little water in the cell, which may lead to the cell shrinking.

Front

Define passive transport.

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, moving along the concentration gradient.

Front

Define active transport.

Back

Active transport is the movement of substances across a cell membrane against the concentration gradient, requiring energy (ATP).

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What role do cell membranes play in transport?

Back

Cell membranes regulate the movement of substances in and out of the cell, maintaining homeostasis.
