Photosynthesis vs Cellular Respiration - Difference and C…

Plants make their own food by photosynthesis. Carbon dioxide and water react together in the presence of light and chlorophyll to make glucose and oxygen. The glucose is converted into starch, fats and oils for storage. It is used to make cellulose for cell walls, and proteins for growth and repair. It is also used by the plant to release energy by respiration.

Photosynthesis And Cellular Respiration


Why is photosynthesis important to humans?
Photosynthesis is important because it produces oxygen gas
It is part of the food chain
Because plants make their own food, and then pass their energy on to other living this when eaten
Humans get most fiber and building materials from plants.
The food and energy from it is how we survive
Plants wouldn't grow without it
Although, they depend of them
It ensures life continues to exist & both are needed by living things.
cellular respiration takes organic compounds and makes them carbon dioxide.


The Cell, Respiration and Photosynthesis


It help maintain good amount of oxygen in the atmosphere
Photosynthesis gives oxygen for life and for cellular respiration
Cellular respiration gives off carbon dioxide, for plants, algae and bacteria to make into oxygen again
Keeps natural ecological balance of earth in place
Photosynthesis takes carbon dioxide and turns it into organic compounds
Photosynthesis:
-Occurs in the presence of light
-Needs energy to make sugar
-Complex substances are formed from simpler ones
-Carbon Dioxide and water are the raw materials
-Oxygen is given out
-Maintains balance of oxygen and carbon dioxide in nature
Cellular respiration:
-Occurs at all times in the cells
-Releases energy from sugar
-Complex substances are broken down into simpler ones
-Carbon Dioxide and water are waste materials
-Oxygen is taken
It also provides energy to sustain every living thing on earth.
