welcome to moo moo math and
wouldn't it be nice if you could take the exhaust of your car and used it as fuel for your motorcycle
and the exhaust of your motorcycle and use it for your car
you would have a nice cycle in which both the car and motocycle benifit.
photosynthesis and cellular respiratin have a similar relationship
the waste product of photosynthesis is used in cellular respiration and the waste product of cellular respiration is fuel for photosynthesis
In order to stay alive we need to eat
Do plants need food?
How do plants get food by just standing around all day?
Plants get their energy using a process called photosynthesis
In order for photosynthesis to take place, a plant needs three items
water like you see in this rainstorm
carbon dioxide found in the atmosphere and we breathe out and is released into the atmosphere when organic objects burn
and sunlight
here is how it works
Plants have small openings called stomata
carbon dioxide in the atmosphere enter these tiny openings
plants have small organelles called chloroplasts
photosynthesis occurs at the chloroplasts
plants take carbon dioxide plus water and energy from the sun and in a chemical reaction like this explosion creates sugar in the form of glucose and oxygen
the sugar created in the chemical reaction called photosynthesis is used by the plant to create energy and the oxygen is released into the atmosphere
the definition of photosynthesis  is the process in which plants  combine carbon dioxide and water along with light energy in order to create sugar and water
Why is cellular respiration important?
It is important because  living organisms generate energy for their daily activities using cellular respiration
cellular respiration takes place at the mitochondria
think of the mitochondria as a power plant for cells similar to how cities using power plants for energy
here is how it works in basic terms
at the mitochondria, the sugar is combined with oxygen to produce carbon dioxide water and energy in the form of ATP
In summary
Photosynthesis takes carbon dioxide and water plus sunlight to create oxygen and sugar which is exactly what cellular respiration needs
cellular respiration takes the sugar and oxygen to create carbon dioxide and water plus ATP which helps with photosynthesis
and this cycle repeats over and over again
