Which of the following is true about which of the following is true about plants and cellular energy? plants and cellular energy?

The correct option is:

Plant uses light energy to produce food molecule during photosynthesis and obtain cellular energy from the bond of these molecule during respiration .

Explanation:

Important points :

Photosynthesis : It is a  process in which green plants prepare their food  using sunlight from CO2 and water .

Here, Food is produced

Respiration : It is a process by which organism obtain energy by breaking the food molecules.

Food molecules are source of energy which contain a large number of bonds. When these bonds break down during respiration , then energy is released .

= food molecule prepared by plants during photosynthesis . It contain many bonds

Hence The bond breaking release energy.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

the answer would be a
