Photosynthesis: The Process of Making Food

Photosynthesis is a critical process that occurs in the chloroplasts of plant cells. It involves the conversion of light energy into chemical energy, which is stored as glucose (a type of sugar). The process requires several key components: light, carbon dioxide, water, and chlorophyll. Chlorophyll, the green pigment in plants, captures light energy from the sun. This energy is then used to convert carbon dioxide, absorbed from the air, and water, absorbed from the soil, into glucose. Oxygen is released as a byproduct and is essential for the survival of most living organisms.

Oxygen is the byproduct of photosynthesis that is essential for human survival.

1 answer

Here are the answers to the statements regarding photosynthesis:

  1. In photosynthesis, carbon dioxide and water are converted into oxygen. - False
    (While oxygen is released as a byproduct, carbon dioxide and water are primarily converted into glucose.)

  2. Oxygen is the gas used by plants as a reactant during photosynthesis. - False
    (Carbon dioxide is the gas used as a reactant; oxygen is produced as a byproduct.)

  3. During photosynthesis, oxygen is released as a byproduct. - True
    (Oxygen is indeed a byproduct of the photosynthesis process.)

  4. The primary purpose of photosynthesis is to produce glucose. - True
    (The main goal of photosynthesis is to convert light energy into chemical energy in the form of glucose.)

  5. Chlorophyll absorbs light energy from the sun. - True
    (Chlorophyll is responsible for capturing light energy necessary for the photosynthesis process.)

  6. Oxygen is the byproduct of photosynthesis that is essential for human survival. - True
    (Oxygen released during photosynthesis is critical for humans and most other living organisms to survive.)
