What is photosynthesis?

Back

Photosynthesis is a biological process used by autotrophs to convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What is the main pigment involved in photosynthesis?

Back

Chlorophyll is the main pigment responsible for absorbing light energy in chloroplasts during photosynthesis.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is diffusion?

Back

Diffusion is the movement of particles from a region of high concentration to a region of low concentration.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is necessary for the process of photosynthesis.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, while heterotrophs obtain their food by consuming other organisms.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas, which drives the movement of particles during diffusion.

Front

What is the function of the cell membrane?

Back

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