autotrophs

an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.

heterotrophs

A heterotroph is an organism that eats other plants or animals for energy and nutrients.

How do plants capture the energy of sunlight?

Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy.

Components of chloroplasts

the outer membrane, the inner membrane, and the thylakoid system.

The products of photosynthesis

During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen

The products of light dependent reactions

The three products of the light reaction of photosynthesis are ATP, NADPH, and O2.

The products of light independent reactions

The products of the light independent reaction are glucose, NADP+, and H2O.

Define carbon fixation

Carbon fixation is the process by which plants fix atmospheric carbon to form organic compounds
