FAQs on Root System Video Lecture - Science & Technology for State PSC Exams - BPSC (Bihar)

1. What is a root system in plants?
Ans. A root system in plants refers to the network of roots that anchor the plant in the soil and absorb water and nutrients. It consists of primary roots, lateral roots, and root hairs, all of which work together to support the plant's growth and development.
2. How does a root system help plants?
Ans. A root system plays a vital role in plants as it provides stability by anchoring the plant in the soil. Additionally, the root system absorbs water and nutrients from the soil, which are essential for the plant's survival and growth. It also helps in storing food reserves and can contribute to vegetative propagation in some plants.
3. What are the types of root systems?
Ans. There are two main types of root systems: taproot systems and fibrous root systems. Taproot systems have a primary root that grows vertically downwards and gives rise to lateral roots. Examples include carrots and radishes. Fibrous root systems, on the other hand, have a cluster of roots that spread horizontally near the surface, providing excellent anchorage. Grasses and wheat are examples of plants with fibrous root systems.
4. How does the structure of a root system vary in different plant species?
Ans. The structure of a root system varies among different plant species. Some plants have a well-developed taproot system with a dominant primary root, while others have a fibrous root system with numerous thin roots of similar size. The depth and spread of the roots also differ depending on the plant's habitat and requirements. For example, plants in dry environments may have deep taproots to access water deep underground.
5. Can the root system of a plant regenerate if damaged?
Ans. Yes, the root system of a plant can regenerate if damaged. The ability to regenerate depends on the severity of the damage and the plant's species. In some cases, if the primary root is damaged or removed, lateral roots can develop into new primary roots. Additionally, root cuttings can be taken from certain plants and grown into new plants through vegetative propagation. However, it is important to note that not all plants have the same regenerative capacity.
