Plants are photoautotrophs. what does this mean? plants are photoautotrophs. what does this mean? they generate oxygen. they are the primary consumers of the biosphere. they are attracted to light. they synthesize their own food from inorganic materials. they use light energy to drive the synthesis of organic molecules from inorganic materials.

Photosynthesis occurs in their Chloroplasts, which only plants have. This means that plants undergo photosynthesis to create their own energy. Water(from the ground) + CO2(Carbon Dioxide) + Light(Energy) = glucose(sugar or energy) + oxygen. The glucose is the energy that all organisms need to function. Plants just use photosynthesis to make it. Photosynthesis occurs in their Chloroplasts, which only plants have.
