FAQs on Vascular Tissue System Video Lecture - Biology for ACT

1. What is the vascular tissue system?
Ans. The vascular tissue system is a complex network of specialized tissues found in plants. It consists of two main types of tissues, xylem and phloem, which are responsible for the transport of water, nutrients, and sugars throughout the plant.
2. What is the function of xylem in the vascular tissue system?
Ans. Xylem is responsible for the transport of water and minerals from the roots to the rest of the plant. It consists of long, hollow cells called tracheids and vessel elements, which are interconnected to form continuous tubes. Xylem also provides structural support to the plant.
3. What is the function of phloem in the vascular tissue system?
Ans. Phloem is responsible for the transport of sugars, amino acids, and other organic compounds from the leaves to the rest of the plant. It consists of living cells called sieve elements, which are interconnected to form sieve tubes. Phloem also plays a role in the storage and distribution of nutrients.
4. How does the vascular tissue system contribute to plant growth and development?
Ans. The vascular tissue system plays a crucial role in plant growth and development. It allows for the efficient transport of water, nutrients, and sugars, which are essential for various metabolic processes and cell activities. Additionally, the xylem provides structural support, helping the plant withstand gravity and grow upright.
5. What are the similarities and differences between xylem and phloem in the vascular tissue system?
Ans. Both xylem and phloem are components of the vascular tissue system, but they have distinct functions and structures. Xylem transports water and minerals unidirectionally from roots to shoots, while phloem transports sugars and other organic compounds bidirectionally. Xylem consists of mainly dead cells, such as tracheids and vessel elements, while phloem contains living cells called sieve elements.
