FAQs on Synthesis of Plant Food other than Carbohydrates Video Lecture - Science Class 7

1. How do plants obtain nutrients other than carbohydrates?
Ans. Plants obtain nutrients other than carbohydrates through various processes such as photosynthesis, absorption, and symbiotic relationships. During photosynthesis, plants convert sunlight into energy and produce carbohydrates. However, they also absorb essential minerals and nutrients from the soil through their roots. Additionally, some plants form symbiotic relationships with beneficial fungi, known as mycorrhizae, which help in nutrient absorption.
2. What are the essential nutrients for plant growth other than carbohydrates?
Ans. Apart from carbohydrates, plants require several essential nutrients for their growth. These include nitrogen, phosphorus, potassium, calcium, magnesium, and trace elements like iron, manganese, zinc, copper, molybdenum, and boron. These nutrients play crucial roles in various plant functions, such as photosynthesis, cell division, root development, and overall plant health.
3. How are nutrients transported within plants?
Ans. Once absorbed by the roots, nutrients are transported within the plants through the vascular system. The xylem tissue primarily carries water and minerals from the roots to the leaves, while the phloem tissue transports sugars and other organic compounds produced during photosynthesis to different parts of the plant. This transportation system ensures that nutrients reach all the plant's cells and tissues, ensuring proper growth and development.
4. Can plants produce their own nutrients other than carbohydrates?
Ans. While plants can produce carbohydrates through photosynthesis, they cannot produce all the necessary nutrients on their own. Plants require external sources, such as the soil, to obtain essential minerals and trace elements. These nutrients are essential for various metabolic processes and cannot be synthesized by plants. Therefore, plants heavily rely on the soil and their surrounding environment for a diverse range of nutrients.
5. Do different plants have different nutrient requirements other than carbohydrates?
Ans. Yes, different plants have varying nutrient requirements other than carbohydrates. Each plant species has specific nutritional needs based on factors like its growth rate, flowering, fruiting, and environmental conditions. For example, some plants might require higher levels of nitrogen for lush foliage growth, while others may need more phosphorus for flower and fruit production. Understanding the specific nutrient requirements of different plants is important for maintaining their health and optimizing their growth.
