The correct answer is 3) Xylem. Explanation & Key Takeaways: Plant tissues are broadly classified into simple tissues and complex tissues based on their structure and function: • Simple tissues consist of one type of cell. Examples of simple tissues are: • Parenchyma: Involved in photosynthesis, storage, and secretion. It consists of thin-walled, living cells. • Sclerenchyma: Provides mechanical support to the plant. It has thick, lignified cell walls and is composed of two types of cells: sclereids and fibers. • Collenchyma: Provides flexible support to growing parts of the plant. It has unevenly thickened cell walls. • Complex tissues, on the other hand, are made up of more than one type of cell. Xylem is an example of a complex tissue. It is made up of several types of cells, including: • Tracheids and vessel elements (responsible for water conduction), • Xylem fibers (providing support), • Xylem parenchyma (storage). • Xylem is primarily involved in the transport of water and minerals from roots to other parts of the plant and also provides structural support. • Conclusion: • Since Xylem is composed of different types of cells, it is classified as a complex tissue. Therefore, the correct answer is: Xylem.
