In this article, the following topic “Nutrition in the Plants” from Class 10th Science- Biology is discussed. Nutrition in the Plants Green plants are autotrophic and synthesize their own food by the process of photosynthesis. The process, by which green plants make their own food from carbon dioxide and water by utilizing sunlight energy in the presence of chlorophyll, is called photosynthesis. Oxygen is released during photosynthesis. The process of photosynthesis can be represented as: The process of photosynthesis takes place in the green leaves of a plant. The food is made by the green leaves of a plant in the form of a simple sugar called glucose.

2. The extra glucose is changed into another food called starch. This starch is stored in the leaves of the plant. The green plants change sunlight energy into chemical energy by producing carbohydrates. The extra glucose is changed into another food called starch. This starch is stored in The extra glucose is changed into another food called starch. This starch is stored in ange sunlight energy into chemical energy by producing ange sunlight energy into chemical energy by producing The photosynthesis takes place in the following e photosynthesis takes place in the following steps: 1. Absorption of sunlight energy by chlorophyll. 2. Conversion of light energy into chemical energy, and splitting of water into hydrogen and oxygen by light energy. 3. Reduction of carbon dioxide by hydrogen to form carbohydrate like glucose by utilizing the chemical energy. Absorption of sunlight energy by chlorophyll. Conversion of light energy into chemical energy, and splitting of water into hydrogen Reduction of carbon dioxide by hydrogen to form carbohydrate like glucose by utilizing Reduction of carbon dioxide by hydrogen to form carbohydrate like glucose by utilizing Conversion of light energy into chemical energy, and splitting of water into hydrogen Conditions necessary for photosynthesis The conditions necessary for photosynthesis to take place are: The conditions necessary for photosynthesis to take place are: Conditions necessary for photosynthesis: 1. Sunlight 2. Chlorophyll 3. Carbon dioxide 4. Water.

3. Green leaves make starch as food. Starch gives a blue solution. Green leaves make starch as food. Starch gives a blue-black color with iodine black color with iodine Raw materials for photosynthesis: The raw materials for photosynthesis are: Raw materials for photosynthesis: tosynthesis are: 1. Carbon dioxide 2. Water How the plants obtain carbon dioxide? How the plants obtain carbon dioxide? There are a large number of tiny pores called stomata on the surface of the leaves of plants. The carbon dioxide gas enters the leaves of the plant through the stomata present on their surface.  Each stomatal pore is circumvented by a dyad of guard cells. When water flows into the guard cells, they swell, become bend and cause the pore to open. On the other hand, when guard cells lose water, they contracts, become straight and close the stomatal pores. There are a large number of tiny pores called stomata on the surface of the leaves of There are a large number of tiny pores called stomata on the surface of the leaves of The carbon dioxide gas enters the leaves of the plant through the stomata present on The carbon dioxide gas enters the leaves of the plant through the stomata present on Each stomatal pore is circumvented by a dyad of guard cells. When water flows into the guard cells, they swell, become bend and cause the pore to When water flows into the guard cells, they swell, become bend and cause the pore to On the other hand, when guard cells lose water, they contracts, become straight and On the other hand, when guard cells lose water, they contracts, become straight and How the plants obtain water for photosynthesis: How the plants obtain water for photosynthesis: The water necessitates by the plants for photosynthesis is absorbed by the root of the plants from the soil through the process of osmosis. The water absorbed by the roots of the plants is conveyed upward through the xylem vessels to the leaves where it reaches the photosynthetic cells. vessels to the leaves where it reaches the photosynthetic cells. The water necessitates by the plants for photosynthesis is absorbed by the root of the The water necessitates by the plants for photosynthesis is absorbed by the root of the plants from the soil through the process of osmosis. The water absorbed by the roots of the plants is conveyed upward through the xylem The water absorbed by the roots of the plants is conveyed upward through the xylem 1. The plants also need other raw materials such as nitrogen, phosphorus, iron, and magnesium, etc., for building their body. 2. The plants take these materials from the soil. The plants take these materials from the soil. The plants also need other raw materials such as nitrogen, phosphorus, iron, and The plants also need other raw materials such as nitrogen, phosphorus, iron, and ng their body.

4. 3. Nitrogen is an essential element used by the plants to make proteins and another compound. Nitrogen is an essential element used by the plants to make proteins and another Nitrogen is an essential element used by the plants to make proteins and another Site of photosynthesis: Chloroplasts Site of photosynthesis: Chloroplasts A chloroplast is a chlorophyll Chloroplasts are present in the photosynthetic cells (mesophyll cells) of green plants. These cells contain more chlorophyll than other plant cells. These cells contain more chlorophyll than other plant cells. is a chlorophyll-containing organelle found in plant cells and some algae. Chloroplasts are present in the photosynthetic cells (mesophyll cells) of green plants. Chloroplasts are present in the photosynthetic cells (mesophyll cells) of green plants. cells and some algae.
