Does photosynthesis occur at night?

A:

Quick Answer

Photosynthesis does not occur during the night. For photosynthesis to take place, water, carbon dioxide and sunlight are necessary, the last of which is missing.

Full Answer

Photosynthesis is the process by which green plants manufacture their own nutrition in their green leaves. The cells of their green leaves contain cell organelles called chloroplasts. These chloroplasts contain a green coloring pigment called chlorophyll. Chlorophyll converts sunlight into chemical energy in the form of simple sugars such as glucose, which serves as food for the cells. Green plants are called autotrophs, as they produce their own food; this process forms the basis for life on earth. Oxygen is released into the atmosphere as a by-product of photosynthesis.

  • Q:

    What is the waste product of photosynthesis?

    A:

    Photosynthesis, which is the process through which some living organisms, including most plants and some fungi, make their own food, produces oxygen as a waste product. The process of photosynthesis in plants is the reverse of the respiration process in humans. While humans breathe in oxygen and expel carbon dioxide, plants ingest carbon dioxide and dispel oxygen.

  • Q:

    What is the overall equation for photosynthesis?

    A:

    Photosynthesis is a chemical reaction that converts solar energy to chemical energy and has the chemical equation of 6H2O + 6CO2 --> C6H12O6 + 6O2. The overall reaction of photosynthesis is catalyzed by solar energy and produces glucose for plants and oxygen for the atmosphere.

  • Q:

    Where in a plant does photosynthesis happen?

    A:

    Photosynthesis occurs in plants and certain types of algae, in the structures known as chloroplasts. The leaves of a plant are the primary location where photosynthesis takes place, with very little occurring in the stems or branches.

  • Q:

    What are the four things needed for photosynthesis?

    A:

    Photosynthesis can only occur when a plant has access to water, carbon dioxide, sunlight and chlorophyll. Plant cells naturally produce chlorophyll, and they draw carbon dioxide directly from the air. Water and sunlight must be acquired from external sources.
