FAQs on Transportation in Plants Video Lecture - General Awareness for SSC CGL
| 1. How do plants transport water and nutrients? |  |
Ans. Plants transport water and nutrients through specialized tissues called xylem and phloem. Xylem carries water and minerals from the roots to the rest of the plant, while phloem transports sugars and other nutrients produced through photosynthesis to different parts of the plant.
| 2. What is transpiration and how does it affect plant transportation? | |
Ans. Transpiration is the process by which water vapor is released from the stomata on the leaves of a plant. This loss of water creates a negative pressure in the xylem, which helps in pulling up water and nutrients from the roots to the leaves through a process called transpirational pull. Transpiration also helps in cooling the plant and maintaining its internal water balance.
| 3. How does temperature affect the rate of transportation in plants? | |
Ans. Temperature can significantly impact the rate of transportation in plants. In warmer temperatures, transpiration rates increase, leading to a higher rate of water uptake from the roots. However, extremely high temperatures can also result in excessive water loss through transpiration, which can stress the plant and affect its overall transportation process.
| 4. What is the role of guard cells in plant transportation? | |
Ans. Guard cells are specialized cells located on the surface of plant leaves that control the opening and closing of stomata. When the guard cells swell with water, the stomata open, allowing for the exchange of gases and the release of water vapor during transpiration. By regulating the opening and closing of stomata, guard cells help in controlling the rate of water loss and gas exchange in plants.
| 5. How does the structure of roots contribute to the transportation of water and nutrients in plants? | |
Ans. The structure of roots, including root hairs and the root system, plays a crucial role in absorbing water and nutrients from the soil. Root hairs increase the surface area for absorption, while the root system extends deep into the soil to access water and minerals. This efficient absorption system ensures that water and nutrients can be transported to the rest of the plant through the xylem tissue.
