Theory about the relationship between photosynthesis and respiration

Why must we study photosynthesis?

- We need to know our food producer
- Also understand how the plant provides us with oxygen
-Also learn how the plants make food/or photosynthesize
-Our quality of life depends on it
-Ensures all life is sustained on Earth
-Photosynthesis can provide raw materials for a range of human needs
-Understanding of photosynthesis may lead to better methods of harvesting solar energy


What is the importance of photosynthesis?

-It provides oxygen , which is essential for us to live
-Food is being made in the photosynthetic parts of the plants ; which also helps the plant to continue surviving
-Removes carbon dioxide from the environment in the day
-The energy in the food made by them is passed on to us when we eat plants thus giving us energy
-Not to allow large amount of carbon dioxide to accumulate in the atmosphere which may cause global warming



How will photosynthesis affects us?

-It affects the ecosystem as plants are a source of food
-If there is no air in the environment , we would die or we would get tanned by the sun
-Many living things may die if plants are scarce
-Carbon dioxide will not be removed from the environment which causes it to accumulate in the atmosphere, which may cause global warming and it leads to unpredictable weather patterns or even violent storms
-GO hungry if plants are also scarce



Our initial theory : Both give out air

A better theory : They balance each other up. Photosynthesis need carbon dioxide and water produced by transpiration and transpiration needs oxygen, which is produced by photosynthesis ... Therefore both processes are equally important because without either one the plant cannot survive and when this happens , many bad things are going to happen :(
