Question

what is callenchyma, sclerenchyma and parenchyma​

Answer 1

Answer:

COLLENCHYMA=====

Collenchyma tissue is composed of elongated cells with irregularly thickened walls. They provide structural support, particularly in growing shoots and leaves. Collenchyma tissue makes up things such as the resilient strands in stalks of celery.

SCLERENCHYMA====

Sclerenchyma cells are strong, thick cells that provide most of the support in a plant. They are known to have extremely thick cell walls and do not participate in many of the other activities of the developing plant, such as photosynthesis, because their focus is strictly on support and structure.

PARENCHYMA=======

The word 'parenchyma' just means the bulk of a thing, but in plants specifically, parenchyma cells are thin-walled cells that make up the inside of many non-woody plant structures including stems, roots, and leaves.

Answer 2

$\huge\boxed{<strong><em>C</em></strong><strong><em>o</em></strong><strong><em>llenchyma</em></strong>}$ : -

Collenchyma Tissues have thick walled longer cells

which compared with parenchyma.

$\huge\boxed{<strong><em>Sclerenchyma</em></strong>}$ : -

In the Sclerenchyma the cells are thick walled and

tightly packed without space. so when compared with dermal

tissue, the ground tissue is of various types has some of the

ground tissue help in photosynthesis.

$\huge\boxed{<strong><em>Parench</em></strong><strong><em>yma</em></strong>}$ : -

The cells of the parenchyma are soft, thin walled and

loosely packed. the parenchyma which contains chloroplast

is called chlorenchyma. the parenchyma which contains large

air cavities or spaces is called aerenchyma. the parenchyma

which stores water or food or waste products is called

storage tissues.
