Question

6. The living cells of
Differentiate between the following.
1. Collenchyma and sclerenchyma
2. Cuboidal and squamous epithelium
3. Ligament and tendon
4. Connective and muscular tissue
5. Meristematic and permanent tissue's​

Answer 1

Answer:

Parenchyma – They are living cells and walled, soft in nature due to the presence of thin-walled cells

Collenchyma – These are characterized by uneven thick-walled living cells.

Sclerenchyma – They have cells with thickened lignified walls, providing them strength and making them waterproof.

Answer 2

Parenchyma

Living tissues with thin cell wall with central vacuole and dense cytoplasm. Parenchyma cells are located in the soft parts of the plants such as pith and cortex.

Sclerenchyma

These are dead tissues which have thick cell wall due to deposition of lignin. They are generally located in the leaf veins, hard coverings of the seeds and can also be found surrounding the vascular bundle.

Collenchyma

Living tissues which have an elongated shape and thick cell wall in the corner. Collenchyma tissue can be located in the leaf stalks, below the epidermis, etc.

Epithelial tissues

Epithelial tissues are covering or protective tissues in the animal body. Almost all organs and cavities are covered by Epithelium.
