Question

What is Epidemics and Cork
what do you understand by the protective layer

Answer 1

Epidermis is the out layer it protects the outside one from dangerous by the protective covering.

Cork cambium (pl. cambia or cambiums) is a tissue found in many vascular plants as part of the periderm. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots (Anshuman monocots usually lack secondary growth). is one of the plant's meristems – the series of tissues consisting of embryonic (incompletely differentiated) cells from which the plant grows. It is one of the many layers of bark, between the cork and primary phloem. The function of cork cambium is to produce the cork, a tough protective material

The protective tissue protects the substance.
PROTECTIVE TISSUE: -

These tissues are usually present in the outermost layer of the plant body such as leaves, stem and roots. It is one cell thick and covered with cutin and protects the underlying tissues present in the plant body.

As roots and stems grow older with time, tissues at the periphery become cork cells. Cork cells are dead, have no intercellular spaces and the cell walls are heavily thickened by the deposition of suberin. They prevent loss of water.

I hope it will help for u ☺.
