Plant cells can synthesize energy-rich organic molecules, and later break them down to extract that energy for performing life processes. these activities require direct interaction between the

Chloroplast and Mitochondria

Explanation:

Plants are autotrophic organisms i.e. capable of producing their own food. They do this through the process of photosynthesis, which is the process that utilizes carbondioxide (CO2) and water in the presence of light energy from sun to produce energy rich organic molecules (glucose) that they use as fuel. This process of photosynthesis occurs in the thylakoid membrane (light dependent reaction) and stroma (light independent reaction) of the CHLOROPLAST.

6CO2 + 6H2O +ATP > C6H12O6 + 6O2

Plants undergo the direct opposite of the photosynthetic process by breaking down the produced organic molecule, in which the freed energy is used to power the plant's life processes. This metabolic process of breaking down organic molecule to release carbondioxide, water and ATP (energy currency) is called CELLULAR RESPIRATION. In the presence of oxygen, it occurs in three stages; Glycolysis, Kreb's cycle, and Oxidative phosphorylation in which the last two occurs in MITOCHONDRIA of plant cells. A total of 36 ATP molecules are produced in plant cells like other eukaryotic cells.

These two plant processes involve a direct interaction between the chloroplast and mitochondria organnelles, in which the photosynthetic process (occuring in the chloroplast) produces energy-containing organic molecule and cell undergoes respiration to break down the organic molecule in order to release the stored energy (ATP) in the mitochondria
