Question

Tissue present in husk of coconut is?

Answer 1

Tissue:

1. A group of cells that have similar structure and function together as one unit is known as tissue.
2. Plant tissues are broadly of two types, meristematic and permanent tissues.
3. Meristematic tissues are further divided into apical meristem, lateral meristem and intercalary meristem.
4. Permanent tissue is further divided into simple and complex.
5. The simple tissues are of three different types: parenchyma, collenchyma and sclerenchyma.

Meristematic tissue:

1. Meristematic tissue is the plant tissue that has the ability to divide.
2. These tissues contain undifferentiated cells.
3. The cells of these tissues are known as meristems.
4. Meristems help to increase girth and length of the plant.

Permanent tissue:

1. The tissues which have completely lost their ability to grow are called permanent tissues.
2. Meristematic tissue divides and differentiates to form permanent tissue.

Husk of coconuts:

1. Sclerenchyma is present in the husk of coconut.
2. In this tissue, cell division is ceased.
3. Sclerenchyma is characterized by the presence of thickened lignified cell walls providing the plant with mechanical support and imparting the property of being waterproof.
4. These tissues have a chemical named lignin, which acts as a cement, causing the hardening.
