The basic function of photosynthesis is for autotrophs (plants/algae) to produce glucose (sugar) for growth/repair/reproduction.

They do this by harnessing the suns energy and converting it into stored chemical energy (sugars).

Photosynthesis makes carbohydrates and species that can perform it are primary producers in ecosystem food webs.

Biologist often use chemical equations to describe the reactions that occur inside of cells. Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light energy + H₂O --> O₂ + glucose

• CO₂ + glucose + H₂O --> O₂ + light energy

• O₂ + light energy + H₂O --> CO₂ + glucose

A plant species lives in an area with limited sunlight. Which physiological adaptation would be most useful to the plant? 

• colorful flowers

• large leaves

• deep roots

• thin cuticle

Answer explanation

Leave are the part of a plant that contains chloroplasts. Chloroplasts are structures that contain chlorophyll, a pigment that captures sunlight and allows the plant to make sugars. The larger the leaf surface a plant has, the more sunlight it can capture.
