Question

What is the final outcome of photosynthesis.
a) Carbon dioxide
b) Nitrogen
c) Water
d) Carbohydrates and oxygen gas

Answer 1

Water and carbon dioxide are used as raw material for the process of photosynthesis. The byproduct of the photosynthesis used by the other living organism for the process of respiration is Oxygen gas. In the form of glucose, the plants produce their food and in the form of starch, they store it.

Complete answer:
The green plants are the plants that are autotrophic in nature and by the process of photosynthesis, they can synthesize their own food. In the presence of chlorophyll pigment, plants prepare food from carbon dioxide and water plants by using sunlight energy.
-The green color pigments that are found in the chloroplast of the leaves are the chlorophyll pigment.
-the carbon dioxide is the air which is required by the green plants for the preparation of food and usually enters through stomata into the plant.
-the second raw material of photosynthesis is the water that usually enters into the plant by root hairs. From the root hairs, water is absorbed from the soil and then transported through the xylem to other parts of green plants like stems, leaves, flowers, etc.
-Through the process of photosynthesis, food that is prepared by the plants is stored in the form of glucose. In green leaves, this glucose is prepared and transported to other parts of the plants via the phloem, like stems, roots, flowers, etc.
-In the form of starch, extra glucose is stored. An example of carbohydrates is both starch and glucose.
-Also, the light energy of sunlight is converted into chemical energy by the green plants, and this energy is utilized by many other organisms for their growth and metabolic activities.
-Carbon dioxide and water are the substrate of photosynthesis whereas carbohydrate is the final product of photosynthesis which includes glucose and oxygen.

So, the correct answer is, option d) "carbohydrates and oxygen gas".

Note:
-Organisms that synthesize their own food with the help of photosynthesis are known as autotrophic organisms.
-The small pores present on the epidermis of the leaves are the stomata that function in the exchange of gases and transpiration.
