Rohan's statement fits simple tissues like parenchyma, where all the cells are of one kind doing one job.

Rajiv is right about complex tissues like xylem and phloem. These are made of more than one type of cell (for example, vessels, tracheids and parenchyma in xylem) working together for one overall function, transport. So they are still one tissue, but not all cells are alike.
