A. It assumes that the natural world works according to rules
<span>Periderm is a term used to refer as the multilayered system of tissues, which is usually made of cork or phellem. When plant's girth is increased due to its secondary growth, they replace epidermal tissues with periderm. Periderm constitutes phellem or cork cells whose walls are thick with a waxy substance called the suberin which protects the surface of the cells and waterproofs them. This secondary covering are formed on small woody plants from the phellogen, a meristematic cell layer which is responsible for the periderm's development.

Answer: Option A) Lipids
Explanation:
Lipids especially phospholipids serves the structural components of many biological membranes due to its hydrophobic heads and hydrophilic tails that forms the bilayer present in most internal organs of the body
Answer:
Yes.
Explanation:
Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules because plants have various signaling molecules that plays a great role in their growth and development. Ethylene, auxin, cytokinins, gibberellins, and abscisic acid are the growth regulators that controls the growth of plants in different conditions i.e. in resistance. These signals leads the plant to take measures in difficult situations experience by the plants so in this way the plant is resistance to the harsh environmental condition.
