Answer 2

Answer:

It is made up of cells that are thin walled spherical or oval, with intercellular spaces, and a large vacuole in their cytoplasm. It is found in almost all organs of the plant.

Explanation:

Parenchyma

• It is made up of cells that are thin walled spherical or oval.

• They have intercellular spaces.

• In parenchyma, large vacuole is present in their cytoplasm.

• Parenchyma are found almost all organs of the plant.

• The main function of this tissue is to synthesize and stores food.

Collenchyma

• It is made up of elongated or oval cells

• They have no intercellular spaces.

• In collenchyma the cell wall is made up of cellulose.

• Collenchyma is found beneath the epidermis in stems of dicots.

• The main function of this tissue is that they provide elasticity and flexibility to the leaves and stems
