Question

Which of the following is used by green plants for the manufacturing of sugar?
(a) Carbon dioxide
(b) Sunlight
(c) Water
(d) All of the above

Answer 1

The procedure through which plants produce food is referred to as photosynthesis. Photosynthesis is the process during which green plants use sunlight to form their own food. Plants receive water and minerals from the soil by their roots. The chlorophyll uses light energy from the sun to mix carbon dioxide and water.

Complete Answer:
Photosynthesis needs sunlight, chlorophyll, carbon dioxide gas and water. Chlorophyll is a substance altogether green plants, especially within the leaves. Plants absorb water within the soil and carbon dioxide within the air. Plants can carry out photosynthesis only through leaves and not by other parts of the plant. Leaves have a special green pigment called by which assists within the suck up of energy from the sun. The chloroplast present within the cells plays an important role during this process. The steps involved within the process of photosynthesis are - • Absorption of light energy by the sun through chlorophyll located in leaves. • Conversion of light energy chemical energy. In this procedure, the water molecule breaks down into its particular parts hydrogen and oxygen. • Carbon dioxide is refused into carbohydrates like glucose through light energy using the hydrogen and oxygen obtained in the above step.
Glucose is the simple food which is ready first within the process of photosynthesis. Glucose and oxygen are the ultimate result of the photosynthesis process. Starch is the food that is made in plant leaves. Starch may be a polymeric carbohydrate consisting of an outsized number of glucose units linked by glycosidic bonds. It acts as stored energy in plants.

Additional information: The organelle of plant cells during which photosynthesis occurs within the chloroplast of plant cells. The photosynthetic pigment chlorophyll is present within the chloroplast of the cell. It helps to absorb the solar energy. It converts the sunshine energy into energy and helps within the process of photosynthesis. The chloroplast organelles are found on the plant leaves.
So, the correct answer is ‘(d) All of the above’.

Note: Photosynthesis plays a vital role in our environment. The whole body is directly or indirectly hooked in to the method of photosynthesis administered by plants. If photosynthesis doesn't occur in plants then plants cannot synthesize the food. This causes the imbalance in the environment. The plants will not produce oxygen and then no animal life will be capable of living because of the absence of oxygen
