Which of the following are forms of complex permanent tissues?

The correct answer is Option (4) → Xylem and Phloem

Complex permanent tissues are made up of more than one type of cell working together to perform a common function. Xylem and phloem consist of different kinds of cells and are responsible for the transport of water, minerals, and food in plants. 

 

• Meristem: This is an undifferentiated tissue (growth tissue), not a permanent tissue.

• Parenchyma, Collenchyma, and Sclerenchyma: These are Simple Permanent Tissues because they are composed of only one type of cell.

• Chlorenchyma and Aerenchyma: These are specialized types of Parenchyma (simple tissue) modified for photosynthesis and buoyancy, respectively.
