Question

What is the internal energy in plants

?

Answer 1

Heya,

The reserve food material in plants in known as starch.

It is a form of carbohydrate.

Plants don't move or peform more metabolic activities like humans so they require a less amount of energy.

They store in the form of starch.

The reserve food material in animals and humans is glycogen which is a form of glucose.

Hope it helps u..

Answer 2

Plants store starch and animals store glucose as internal energy reserves.
 The internal energy of a system is the energy contained within the system, excluding the kinetic energy of motion of the system as a whole and the potential energy of the system as a whole due to external force fields. It keeps account of the gains and losses of energy of the system that are due to changes in its internal state 
If a system undergoes certain phase transformations while being heated, such as melting and vaporization, it may be observed that the temperature of the system does not change until the entire sample has completed the transformation. The energy introduced into the system while the temperature did not change is called a latent energy, or latent heat, in contrast to sensible heat, which is associated with temperature change.
