Photosynthesis

The Ultimate source of energy of the ecosystem on the earth is the sun.

Photosynthesis

  • The process mostly takes place in the chloroplasts of plant leaf mesophyll cells.

    The energy for photosynthesis comes from light.

  • Light energy is converted to chemical energy by chlorophyll.

    - Photosynthesis is affected by the temperature, light intensity, light wavelength and carbon dioxide level.

    - All living things depend on the Organic Molecules synthesized by plants as a result of photosynthesis.


Photosynthesis Reactants

6CO₂+6H₂O+ light energy

Photosynthesis Products

C₆H12O₆+6O₂+6H₂O

Purpose for Photosynthesis

To make food for plants ( food in the form of glucose, a type of sugar. )


Photosynthesis , plants put together materials make food with the energy of sunlight. It also takes place in the chloroplast.

Cellular respiration is a series of set of metabolic reactions and processes. These reactions takes place in the cells of organisms, where the organisms convert biochemical energy from nutrients into adenosine triphosphate.

Cells gain useful energy to fuel cellular activity through The reaction is considered to be an exothermic redox reaction, the process occurs in many separate steps.


Aerobic Respiration


Aerobic respiration takes place in the presence of oxygen, by which ATP is is produced by the cells by oxidation of organic compounds.


Anaerobic Respiration


Anaerobic respiration is the process used in some microorganisms in which oxygen is not final electron acceptor. This process starts like aerobic respiration and stops part way through because oxygen is not available to finish the respiration process.
