Which is not required for synthesis of carbohydratesa) ...
Explanation:
Synthesis of carbohydrates:
Carbohydrates are synthesized in plants through a process called photosynthesis. During photosynthesis, plants convert carbon dioxide and water into glucose (a type of carbohydrate) using sunlight as an energy source. The process takes place in the chloroplasts of plant cells, specifically in the presence of chlorophyll.
Chlorophyll:
Chlorophyll is a pigment found in the chloroplasts of plant cells. It absorbs sunlight and plays a crucial role in the process of photosynthesis. The energy absorbed by chlorophyll is used to convert carbon dioxide and water into glucose and oxygen. Therefore, chlorophyll is essential for the synthesis of carbohydrates in plants.
Water:
Water is one of the reactants required for photosynthesis. It is obtained by plants through their root system and transported to the chloroplasts where photosynthesis occurs. Water molecules are broken down during photosynthesis, and their hydrogen atoms are used to create glucose. Thus, water is necessary for the synthesis of carbohydrates.
Nitrogen:
Nitrogen is an essential element required for the growth and development of plants. It is a component of amino acids, which are the building blocks of proteins. While nitrogen is necessary for the synthesis of proteins, it is not directly involved in the synthesis of carbohydrates. Carbohydrates are composed of carbon, hydrogen, and oxygen atoms, and nitrogen is not a constituent of carbohydrates.
Carbon dioxide:
Carbon dioxide is another reactant required for photosynthesis. It is obtained by plants from the atmosphere through tiny pores called stomata. Carbon dioxide molecules are combined with water molecules in the presence of sunlight and chlorophyll to produce glucose. Carbon dioxide provides the carbon atoms necessary for the synthesis of carbohydrates.
Conclusion:
Among the given options, nitrogen is not directly required for the synthesis of carbohydrates. While nitrogen is crucial for the synthesis of proteins, it is not involved in the formation of carbohydrates. Chlorophyll, water, and carbon dioxide are essential components for the synthesis of carbohydrates through photosynthesis.
