Question

The cell of epidermal tissues does not have intercellular space because

• A. They are square shaped.
• B. They have a protective fluid.
• C. They have a dense cytoplasm.
• D. Their side walls stick together due to the wax secretion.

Answer 1

The correct option is D Their side walls stick together due to the wax secretion.

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.

Therefore, the correct answer is option D.
