Photosynthesis is the food making process in green plants. Plants use Inorganic molecules such as CO2 and H2O to produce glucose (C612O6)

The product of Photosynthesis is used by animals to supply energy. There are two reactions as we all know it: Light dependent and Light independent. The light dependent reaction is where sunlight is used to break H2O into hydrogen and oxygen, Oxygen is released as a bi product.

Hydrogen + Carbon dioxide (the raw materials) is used to create glucose (C6H12O6). Inorganic molecules (H2O and CO2) are changed into organic molecules (Sugars, Glucose) in photosynthesis. Also, photosynthesis converts light energy to chemical energy.

Respiration → C6H12O6 (breakdown) to CO2+H2O.

Active transport and passive transport are two ways that molecules can move across the cell membrane. The difference is that active transport requires energy where passive transport doesn’t.

In passive transport, molecules move from high concentration area to low concentration area down the concentration gradient.

Examples of Passive Transport: Diffusion, Osmosis, Facilitated diffusion.

In active transport, molecules move against their concentration gradient, from low concentration to high concentration. This requires energy input from the cell in the form of ATP.

Autotrophic organisms produce their own food and Heterotrophic organisms feed on autotrophs or one another.

Additional Information


Uses of Glucose

Glucose is the primary product of photosynthesis and it’s used for:

Cellular Respiration
Production of sucrose, starch, and cellulose.
Provide energy during the synthesis of ATP.
Formation of amino and fatty acids.

Limiting factors of Photosynthesis

Amount of light
Concentration of CO2
Amount of water
