Photosynthesis Quiz

In photosynthesis, the sun's energy is captured in order to make food. Plants use carbon dioxide, water, and sunlight to produce oxygen, water, and food in the form of sugar. Plants make and store excess food that can also be used to provide energy for consumers. Photosynthesis is not unique to plants. Other photosynthetic organisms include some protists, algae, and bacteria known as cyanobacteria.

The process of photosynthesis is vital to life as we know it. This process is responsible for half of the global oxygen supply. Plants, animals, and other organisms need oxygen to live. Oxygen is a necessary component for cellular respiration. In addition, most organisms depend on photosynthetic organisms for nourishment.

In plants and algae, photosynthesis occurs in special organelles known as chloroplasts. Chloroplasts contain chlorophyll, a green pigment which absorbs light energy for photosynthesis. In plants, chloroplasts are found primarily in the leaves. Although cyanobacteria lack chloroplasts, they do contain chlorophyll. Photosynthesis takes place through out special membrane layers found in cyanobacteria.

The chemical equation for the process of photosynthesis is: 6CO2 + 6H2O + light → C6H12O6 + 6O2.
