FAQs on Solved Questions: Transport in Plants Video Lecture - Biology for JAMB

1. What is the process of transport in plants?
Ans. The process of transport in plants is known as translocation. It involves the movement of water, nutrients, and other substances from the roots to the leaves through specialized structures called xylem and phloem.
2. How does water move in plants?
Ans. Water moves in plants through a process called transpiration. Transpiration is the loss of water vapor through the stomata on the surface of leaves. This loss of water creates a pull or suction force, known as transpirational pull, which helps in the upward movement of water from the roots to the leaves.
3. What are xylem and phloem?
Ans. Xylem and phloem are the two types of vascular tissues found in plants. Xylem is responsible for the transport of water and minerals from the roots to the leaves. It consists of specialized cells called tracheids and vessel elements. Phloem, on the other hand, transports sugars, amino acids, and other organic compounds from the leaves to other parts of the plant. It consists of sieve tube elements and companion cells.
4. How do plants transport nutrients?
Ans. Plants transport nutrients through the process of translocation. Nutrients, such as sugars and amino acids, are produced in the leaves through photosynthesis. These nutrients are then transported through the phloem to other parts of the plant, such as the roots, fruits, and flowers, where they are needed.
5. What factors affect the rate of transpiration in plants?
Ans. Several factors affect the rate of transpiration in plants. These include temperature, humidity, wind speed, and the availability of water in the soil. Higher temperatures and lower humidity increase the rate of transpiration, while high wind speeds can increase transpiration by removing the boundary layer of air around the leaf surface. The availability of water in the soil also plays a crucial role in determining the rate of transpiration.
