Plants absorb various essential nutrients from the soil to support their growth and metabolic functions. Nitrogen is acquired in the form of nitrates or ammonium ions, crucial for protein synthesis. Phosphorus, obtained as phosphate ions, is essential for energy transfer and nucleic acid formation.Read more
Plants absorb various essential nutrients from the soil to support their growth and metabolic functions. Nitrogen is acquired in the form of nitrates or ammonium ions, crucial for protein synthesis. Phosphorus, obtained as phosphate ions, is essential for energy transfer and nucleic acid formation. Potassium regulates water uptake, enzyme activation, and overall plant metabolism. Calcium contributes to cell structure and membrane integrity. Magnesium is integral to chlorophyll synthesis for photosynthesis. Sulfur is essential for amino acid formation. Additionally, plants absorb micronutrients like iron, zinc, and copper, playing key roles in enzyme activation and various metabolic pathways.
Plants have lower energy needs compared to animals due to their unique mode of energy acquisition. Through photosynthesis, plants harness sunlight to convert carbon dioxide and water into glucose, storing energy in chemical bonds.

Plants have lower energy needs compared to animals due to their unique mode of energy acquisition. Through photosynthesis, plants harness sunlight to convert carbon dioxide and water into glucose, storing energy in chemical bonds. This process is highly efficient and directly utilizes environmental resources. In contrast, animals must consume organic matter for energy, involving complex digestive processes. Additionally, plants have a slower metabolic rate and fewer energy-intensive activities, as they lack the need for rapid movement and intricate physiological processes. Overall, the direct utilization of sunlight and a less demanding lifestyle contribute to the comparatively lower energy requirements of plants.
The two independently organized conducting tubes in plant transport systems are the xylem and the phloem. The xylem primarily transports water and minerals absorbed by the roots from the soil to various parts of the plant. Composed of vessel elements and tracheids, xylem vessels facilitate unidirectRead more
The two independently organized conducting tubes in plant transport systems are the xylem and the phloem. The xylem primarily transports water and minerals absorbed by the roots from the soil to various parts of the plant. Composed of vessel elements and tracheids, xylem vessels facilitate unidirectional water movement through capillary action and transpiration. In contrast, the phloem is responsible for the bidirectional transport of organic compounds, such as sugars produced during photosynthesis, from source to sink tissues. It consists of sieve tubes and companion cells, forming a network that supports nutrient distribution essential for plant growth and development.
The xylem primarily transports water and minerals in plants. Water absorption occurs at the roots through osmosis, and the xylem vessels, composed of tracheids and vessel elements, facilitate the upward movement of water.

The xylem primarily transports water and minerals in plants. Water absorption occurs at the roots through osmosis, and the xylem vessels, composed of tracheids and vessel elements, facilitate the upward movement of water. Additionally, xylem transports essential minerals, such as ions of nitrogen, phosphorus, and potassium, absorbed from the soil. This process, known as translocation, is essential for the maintenance of turgor pressure, cell structure, and metabolic processes within the plant. The xylem’s unidirectional flow ensures a continuous supply of water and minerals from the roots to various tissues, supporting growth, photosynthesis, and overall plant functioning.
The phloem primarily transports organic compounds, mainly sugars produced during photosynthesis, throughout the plant. This bidirectional transport system ensures the distribution of assimilates from source tissues (such as leaves) to sink tissues (such as roots, developing fruits, and growing buds)Read more
The phloem primarily transports organic compounds, mainly sugars produced during photosynthesis, throughout the plant. This bidirectional transport system ensures the distribution of assimilates from source tissues (such as leaves) to sink tissues (such as roots, developing fruits, and growing buds). The main transported sugars are sucrose, glucose, and fructose. Phloem sap also contains amino acids, hormones, and other metabolic products. Sieve tubes, along with companion cells, form the phloem structure, allowing for efficient translocation of these substances. This process is vital for supplying energy, nutrients, and signaling molecules to different parts of the plant, supporting growth, development, and metabolic activities.
