Question

What are the similarities between simple tissue and complex tissue?

Answer 1

If a group of cells are more or the less the same, then it is known as a Simple tissue e.g. epidermis, parenchyma, collenchyma and sclerenchyma. If, however, the tissue is composed of a number of different cells, then it is known as a Complex tissue such as xylem and phloem.
