Function of Xylem in Plants
Xylem is a crucial tissue in vascular plants, primarily responsible for the transport of water and minerals. Here’s a detailed explanation of its function:
Water Transport
- Xylem transports water from the roots to various parts of the plant, including stems and leaves.
- This process occurs through a mechanism called transpiration, where water evaporates from the leaf surface, creating a negative pressure that pulls water upward.
Mineral Transport
- Along with water, xylem also carries essential minerals and nutrients absorbed from the soil.
- These minerals include nitrogen, phosphorus, potassium, and others that are vital for plant growth and development.
Structural Support
- Besides transport, xylem provides structural support to the plant.
- Its cell walls are thickened and lignified, helping to maintain the plant's upright position and withstand various environmental stresses.
Importance in Plant Growth
- The efficient transport of water and minerals is critical for photosynthesis, the process by which plants make their food.
- Adequate water supply helps in nutrient absorption and promotes overall plant health and growth.
In summary, the primary function of xylem is to transport water and minerals, making option 'B' the correct answer. Understanding the role of xylem is essential for appreciating how plants thrive and maintain their physiological processes.
