Answer:
Option-D
Explanation:
Plants are the organisms present on the Earth which can be easily marked with their green color. The green color is due to the presence of the chloroplast which encompasses the chlorophyll pigment.
The chlorophyll pigment has the ability to capture the sunlight energy which initiates the process of photosynthesis. The photosynthesis process utilizes Carbon dioxide gas and water to form glucose molecules.
The glucose molecule is then transported to the other parts of the plants like stem and roots where photosynthesis is absent and to obtain the energy, plant perform cellular respiration. The cellular respiration requires oxygen gas which acts as an electron acceptor molecule.
Thus, Option-D is correct.
Photosynthesis and cellular respiration are very different processes, in
that they require completely different products to produce the
necessary chemical reactions. However, they are similar in that they
both result in energy production for the organisms they are part of.
