What is a plant cell?

Back

A plant cell is a type of cell that contains chloroplasts for photosynthesis and a cell wall for structural support.

Front

What organelles are involved in energy production in plant cells?

Back

Chloroplasts transform light energy into chemical energy, while mitochondria release energy from food.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis is the movement of water across a selectively permeable membrane, while diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What is active transport?

Back

Active transport is the process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is the function of cell membranes?

Back

Cell membranes act as selectively permeable gatekeepers, controlling what enters and exits the cell.

Front

What is the function of cell walls?

Back

Cell walls provide structural support and protection to plant cells.

Front

How do enzymes affect chemical reactions?

Back

Enzymes lower the activation energy required for a reaction, thus speeding up the reaction.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.
