Answer: Without plants there would be no OXYGEN on earth. Plants take all the AIR we breathe and all the FOOD we eat. Plants take energy from the SUN and make their own food in the form of GLUCOSE. Plants take in CARBONDIOXIDE from the air, and give off OXYGEN.
Step-by-step explanation:
Plants are autotrophs which means they are producers. Green plants are able to manufacture their own food through the process known as PHOTOSYNTHESIS.
This process, photosynthesis, is not only important to plants themselves but also to animals and humans, which depends on the products which is oxygen and glucose (food).
The main features of photosynthesis includes:
--> photosynthesis takes place in the chloroplasts of plant cells, in the presence of SUN ( solar energy).
--> The raw materials of the process are the low - energy containing inorganic compounds, for example, the CARBONDIOXIDE and water.
--> The final products of the process are high energy containing sugars (GLUCOSE). Oxygen is given off as a waste product which makes up the AIR we breathe.
--> The energy needed to drive this anabolic process comes from the sunlight absorbed by chlorophyll, the green pigment found in chloroplasts. While the glucose produced are converted to starch and stored in the plant storage organs such as roots, stems, fruits and seeds.
