This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

Be careful not to confuse this photosynthesis equation with respiration which is the reverse of this. The balanced symbol equation shown above is Higher tier only.

Photosynthesis occurs in chloroplasts found within cells. It is the chloroplasts that contain the green pigment chlorophyll which absorbs light. The plant uses this glucose to grow as well as make ...

We often think of animals using oxygen and glucose for cellular respiration and producing carbon dioxide. Similarly, we might think of plants using carbon dioxide and sunlight for photosynthesis and ...
