Cell Unit Test 9B

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, single-celled organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles. Examples include plant and animal cells.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in both prokaryotic and eukaryotic cells.

Front

What is passive transport?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move substances across the cell membrane.

Front

What happens to an animal cell in a hypertonic solution?

Back

An animal cell placed in a hypertonic solution will lose water and shrink.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts convert sunlight into chemical energy through photosynthesis, producing food for the plant.

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.

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 the difference between active and passive transport?

Back

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