FAQs on Upward Water Movement in a Plant Video Lecture - Biology for JAMB
| 1. What is upward water movement in plants? |  |
Ans. Upward water movement in plants refers to the process by which water is transported from the roots to the rest of the plant, including the stem, leaves, and flowers. This movement is essential for the plant's survival as water is needed for various metabolic processes and for maintaining turgidity in plant cells.
| 2. How does water move upwards in plants? | |
Ans. Water moves upwards in plants through a process called transpiration. Transpiration is the evaporation of water from the surface of plant leaves. As water evaporates from the leaves, it creates a negative pressure or tension, which pulls water up through the plant's xylem vessels. This process is known as the cohesion-tension theory.
| 3. What are xylem vessels and their role in upward water movement? | |
Ans. Xylem vessels are specialized structures in plants that are responsible for conducting water and minerals from the roots to the rest of the plant. They are composed of hollow, elongated cells, called tracheary elements, that form a continuous tube for efficient water transport. Xylem vessels play a crucial role in the upward movement of water in plants.
| 4. How does cohesion help in upward water movement in plants? | |
Ans. Cohesion refers to the attraction between water molecules due to hydrogen bonding. In plants, cohesion helps in the upward movement of water by creating a continuous column of water in the xylem vessels. As water molecules evaporate from the leaves, the cohesive forces between water molecules allow them to pull each other up, facilitating the upward movement of water.
| 5. What factors can affect upward water movement in plants? | |
Ans. Several factors can influence the upward water movement in plants. Environmental factors such as temperature, humidity, and wind can affect the rate of transpiration, which in turn affects the rate of water movement. Additionally, the availability of water in the soil, the efficiency of the plant's root system, and the condition of the xylem vessels can also impact the upward movement of water in plants.
