Question

Coir is obtained From
A) Pericarp
B) Bark
C) Stem
D) Leaves

Answer 1

Hint: Coir is obtained from natural fibre. The coconut is referred to as one seeded Drupe or dry drupe. It is made up of lignin and cellulose. The coir is made up of parenchymatous cells; its function is used to store oil droplets.

Complete answer:
INTRODUCTION :
Coir is a seed hair fibre derived from coconut husk. It is present between the strong internal shell and outer layer. The fibre is a reddish brown colour and contains minute threads. They are resistant to water.
A) PERICARP: It is part of a fruit enclosing the seeds that develop from the wall of the ovary. The pericarp consists of an exocarp, fibrous Mesocarp, and endocarp. The coir fibre extracted from the Mesocarp of the coconut fruit is present between the internal and outer layer of the coconut.
B) BARK: It is the outermost layer of woody plants. It covers the tree's trunk and branches. Its main purpose is to conserve water and protect the tree from unfavourable conditions.
C) STEM: Stem is the main Structural axis of the plant. The Coconut stem is called a trunk. It is unbranched, erect, stout and cylindrical. It is present above the soil surface.
D) LEAVES: A healthy crown contains about 30-40 leaves. They are present at the top of the tree near the trunk. The leaves remain in the tree for about 3 years.

Thus, the correct answer is option A) Pericarp

NOTE :
The fibrous husk layer is known as Mesocarp, covering the hard woody layer known as Endocarp. The coir is a natural fibres that have resistance to thermal conductivity, possess high toughness, ductility, and are durable.
