Plants need food to respire, grow and reproduce. Unlike animals, plants are able to make their own food by the process of photosynthesis. Photosynthesis takes place in the part of the plant cell ...

Hydrogen and ATP are both transferred to the second stage of photosynthesis ... are controlled by specific enzymes. The overall process of carbon fixation is summarised in the diagram below.

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 ...

(6-8) Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of ...
