Cells and Cell Transport

Front

What is Exocytosis?

Back

Exocytosis is the process by which a cell forms a vesicle around unwanted particles and expels it out of the cell.

Front

What is the role of chloroplasts and mitochondria in a cell?

Back

Chloroplasts and mitochondria work together to maintain homeostasis by converting the potential energy of organic compounds into a suitable form for immediate use by the cell.

Front

What is the main function of the Golgi apparatus?

Back

The main function of the Golgi apparatus is to process and deliver proteins within the cell.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process where special proteins help move particles across the cell membrane without the need for energy.

Front

What does active transport do?

Back

Active transport moves molecules from low concentration to high concentration, requiring energy.

Front

Define the term 'cell membrane'.

Back

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

What is osmosis?

Back

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

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy to move substances across the cell membrane, while active transport requires energy to move substances against their concentration gradient.

Front

What is the role of lysosomes?

Back

Lysosomes are organelles that contain enzymes to break down waste materials and cellular debris.
