Biology Unit 5 Cell Function Practice

Front

What is the primary function of chloroplasts in plant cells?

Back

Chloroplasts convert light energy into chemical energy in the form of ATP and NADPH during photosynthesis.

Front

What type of cell division is responsible for the growth and development of plants?

Back

Mitosis is the type of cell division responsible for the growth and development of plants.

Front

What organelle is primarily involved in photosynthesis?

Back

Chloroplasts are the organelles primarily involved in photosynthesis.

Front

What happens to plant cells when placed in a saltwater solution?

Back

The cells will shrink within the cell walls due to osmosis.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, moving from areas of high concentration to low concentration.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane using energy (ATP), moving from areas of low concentration to high concentration.

Front

What are examples of passive transport?

Back

Examples of passive transport include osmosis, facilitated diffusion, and simple diffusion.

Front

What are examples of active transport?

Back

Examples of active transport include endocytosis, exocytosis, and sodium ion pumps.

Front

What is osmosis?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of transporting molecules across a cell membrane via protein channels without the use of energy.
