FAQs on NCERT Solutions +extra questions of ch 1 science (nutrition in plants) class 7

1. What is the process of nutrition in plants?
Ans. Nutrition in plants is the process by which plants obtain and utilize nutrients for their growth and development. They use sunlight, water, carbon dioxide, and minerals from the soil to carry out photosynthesis, which helps them produce food (glucose) and oxygen. This food is then utilized by plants for various metabolic activities and growth.
2. How do plants obtain nutrients from the soil?
Ans. Plants obtain nutrients from the soil through their root system. The root hairs present on the surface of the roots absorb water and minerals from the soil. These minerals are transported through the root tissues to the different parts of the plant for their utilization in various metabolic processes.
3. What are the different modes of nutrition in plants?
Ans. Plants can have different modes of nutrition depending on how they obtain their food. The two main modes of nutrition in plants are autotrophic nutrition and heterotrophic nutrition. Autotrophic nutrition refers to the process of plants producing their own food through photosynthesis, while heterotrophic nutrition refers to plants obtaining food from external sources, such as other plants, animals, or decaying organic matter.
4. What are the essential nutrients required by plants for their growth?
Ans. Plants require several essential nutrients for their growth and development. These include macronutrients like nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, which are required in large quantities. Additionally, plants also require micronutrients like iron, manganese, zinc, copper, molybdenum, boron, and chlorine, which are needed in small quantities. These nutrients play vital roles in various physiological processes of plants.
5. How does the process of photosynthesis contribute to plant nutrition?
Ans. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. This glucose serves as the primary source of energy for plants, which is utilized for their growth and other metabolic activities. Additionally, photosynthesis also releases oxygen, which is vital for the survival of many organisms, including humans. Therefore, the process of photosynthesis plays a crucial role in plant nutrition by providing them with the necessary food and releasing oxygen into the environment.
