Question

If there are no intercellular spaces between the cell of epidermal layer, how does exchange or
secretion of materials takes place ?​

Answer 1

Answer:

The epidermis is the outermost cellular layer which covers the whole plant structure, i.e., it covers roots, stem, leaves, flowers and fruit. It is composed of a single layer of living cells, although there are exceptions. Epidermis is usually closely packed, without intercellular spaces or chloroplasts. The outer walls, which are exposed to the atmosphere and usually thickened and may be covered by a waxy, waterproof cuticle which is made up of cutin. So, their side walls stick together due to the wax secretion.
