FAQs on Nutrition in Plants - Life Processes, Class 10 Science Video Lecture

1. What is nutrition in plants?
Ans. Nutrition in plants refers to the process by which plants obtain and utilize the necessary nutrients for their growth and development. This includes the absorption of water and minerals from the soil, synthesis of food through photosynthesis, and the transport of nutrients within the plant.
2. How do plants absorb nutrients from the soil?
Ans. Plants absorb nutrients from the soil through their root system. The root hairs present on the surface of the roots increase the surface area for absorption. Nutrients in the form of ions are taken up by the root hairs through active transport or diffusion. Water is also absorbed along with the nutrients.
3. What is photosynthesis and why is it important for plants?
Ans. Photosynthesis is the process by which green plants produce food using sunlight, carbon dioxide, and water. In this process, plants convert light energy into chemical energy, which is stored in the form of glucose. Photosynthesis is important for plants as it provides them with the energy they need for growth, reproduction, and other life processes.
4. How do plants transport nutrients within their body?
Ans. Plants transport nutrients within their body through a tissue called the vascular tissue. The vascular tissue consists of two types of tissues: xylem and phloem. Xylem transports water and minerals from the roots to the other parts of the plant, while phloem transports sugars and other organic compounds from the leaves to the rest of the plant.
5. What are the essential nutrients required by plants for their growth?
Ans. Plants require several essential nutrients for their growth, including macronutrients and micronutrients. Macronutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, which are required in large quantities. Micronutrients include iron, manganese, zinc, copper, boron, molybdenum, and chlorine, which are required in small quantities. These nutrients play a vital role in various plant processes and deficiencies can lead to stunted growth and other abnormalities.
