Rohan’s statement is correct for simple tissues because they contain similar cells performing one function. Rajiv is also correct because complex tissues contain different types of cells working together for a common function, like xylem and phloem.
During the discussion in class, Rohan gives a statement that, “A tissue is a group of similar cells performing similar functions”. But Rajiv counter argues that, “this is true in case of simple tissues but little different in case of complex tissues”. Provide your explanation in view of the discussion in class.

Simple tissues, such as parenchyma and collenchyma, consist of similar cells performing similar functions, so Rohan’s statement is correct for them. However, Rajiv is correct regarding complex tissues because they contain different kinds of cells working together for one common function. For example, xylem contains vessels, tracheids and fibres, while phloem contains sieve tubes and companion cells.

Both Rohan and Rajiv are correct because Rohan’s statement applies to simple tissues, while Rajiv’s counter-argument correctly describes complex tissues.Rohan’s View: Simple TissuesRohan says a tissue is a group of similar cells performing similar functions.This statement is true for simple permanent tissues.Simple tissues contain only one type of cell.All cells look alike and do the same job.Examples include parenchyma, collenchyma, and sclerenchyma.Rajiv’s View: Complex TissuesRajiv says complex tissues are different.Complex tissues contain more than one type of cell.These different cells do not look the same.However, they all work together as a single unit to finish one common task.Examples include xylem and phloem.
