Question

Hey Guys !!
$\small{\underline{\underline{\mathbf{Short\:Note\:on\:Scherenchyma\:!!}}}}$
​

Answer 1

Answer:

Sclerenchyma

→It is a type of tissue which contains dead cells and have thick secondary walls made up of lignin.

→This tissue provide structural support to plants.

→It is type of vascular tissue which usually die when they are mature but continue to fulfill their structural purpose in the plant.

→There are two types of sclerenchyma cells: fiber cells and sclereids. Compare collenchyma parenchyma .

→They donot have the ability to divide.

→In sclerenchyma there are no intercellular spaces as they are thick and rigid in nature.

Answer 2

$\large{\boxed{\mathcal{About\:SclerenChyma\:!!}}}$

Sclerenchyma is a type of Permanent Tissue.

Permanent Tissue →Formed from meristematic tissues, the cell in the tissue loose the ability to divide.

Permanent tissues are divided into two categories.

Simple permanent Tissue :--

• Parenchyma.
• Cholenchyma.
• Sclerenchyma.

Complex Permanent Tissue :--

• Xylem.
• Phloem.

$\large{\underline{\underline{\mathbf{Note\:For\:Sclerenchyma}}}}$

╰➜It is Composed of long narrow and thick walled cells.

╰➜This tissue is made up of dead celLS and there are no imtercellular spaces.

╰➜Sclerenchyma calls are dead present in seeds, nuts, husk of coconut, fibre of jute etc.

╰➜Their walls are thickened due to lignin deposition.

╰➜They are not flexible and non-living cells.

╰➜Sclerenchyma having two types.

• ✧ Sclereids.
• ✧ Fibres.

╰➜They are specialised cells and providing mechanical support.

╰➜In this vacuoles are absent.
