C8 Review: Cell Structure and Transport

Front

What happens to a cell when it is placed in a hypertonic solution?

Back

The cell will shrink due to water moving out of the cell to balance the concentration of solutes.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process where molecules move across a cell membrane through protein channels, from an area of higher concentration to an area of lower concentration, without the use of energy.

Front

What is the liquid substance in the cytoplasm called?

Back

Cytosol.

Front

What is passive transport?

Back

Passive transport is the movement of particles across a cell membrane without the use of energy, typically from an area of high concentration to an area of low concentration.

Front

Which organelle is responsible for energy production in animal cells?

Back

Mitochondria.

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 do chloroplasts do?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

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.

Front

What is the role of the cell membrane?

Back

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