Step 1
Step 2
Explain how sugars are made in a leaf.
Answer
Sugars are made in a leaf through the process of photosynthesis, which occurs in the chloroplasts of leaf cells. During this process, carbon dioxide (CO2) from the air and water (H2O) from the soil are combined using sunlight energy, which is captured by chlorophyll. The overall equation for photosynthesis can be summarized as:
ightarrow C_6H_{12}O_6 + 6O_2 $$ This results in the production of glucose (C6H12O6) and oxygen (O2). The glucose produced can then be used as an energy source by the plant or stored for later use.
