Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.
On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any
external injuries.

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.
