FAQs on Transportation of Water and Minerals in Plants(Xylem and Phloem) Video Lecture - Science Class 7
| 1. How do plants transport water and minerals? |  |
Ans. Plants transport water and minerals through specialized tissues called xylem and phloem. The xylem carries water and minerals from the roots to the other parts of the plant, while the phloem transports food and other organic substances from the leaves to the rest of the plant.
| 2. What is the function of xylem in plant transportation? | |
Ans. The xylem is responsible for transporting water and minerals from the roots to the other parts of the plant. It consists of long, hollow cells called vessels that create a continuous pathway for the upward movement of water and dissolved nutrients. The xylem also provides mechanical support to the plant.
| 3. How does the phloem transport food in plants? | |
Ans. The phloem is responsible for the transportation of food and other organic substances in plants. It consists of sieve tubes, which are long, cylindrical cells with perforated end walls called sieve plates. These sieve plates allow the movement of sugars and other organic molecules from the leaves, where they are produced through photosynthesis, to other parts of the plant.
| 4. What are the similarities between xylem and phloem? | |
Ans. Both xylem and phloem are vascular tissues found in plants. They are responsible for the transportation of fluids and substances within the plant. Both tissues are composed of specialized cells that form continuous pathways. However, their functions and the substances they transport differ. Xylem transports water and minerals, while phloem transports food and other organic substances.
| 5. How are xylem and phloem different from each other? | |
Ans. Xylem and phloem differ in their structure and function. Xylem is made up of long, hollow cells called vessels, which provide a continuous pathway for the upward movement of water and minerals. Phloem, on the other hand, consists of sieve tubes that transport food and other organic substances through perforated end walls called sieve plates. Xylem transports water and minerals from roots to other parts of the plant, while phloem transports food from leaves to other parts.
