_________ are commonly found in the fruit walls of nut.

Living mechanical tissue with a thickening at the cells corners possess deposition of

1. Lignin

2. Cellulose and pectin only

3. Cellulose, hemicellulose and pectin

4. Cellulose only

Cells having cellulose, hemicellulose and pectin deposits on the wall and shows its presence commonly in the petiole of leaf and growing green stems belong to

1. Sclerenchyma

2. Collenchyma

3. Aerenchyma

4. Parencyma

Identify the mismatched pair:

	Tissue	Feature
1.		Thick walled, elongated and pointed cells present in hypodermis of dicot stem
2.		Forms the major component within plant organs
3.		Commonly found in pulp of fruits like guava, pear and sapota
4.		Provide mechanical support to growing parts of plant

Lignified cell wall is characteristic feature of

Mechanical support to the growing parts of the plant such as young stem and petiole of leaf is provided by a living tissue called

Which of the following has unevenly thick cell wall, has a primary wall (cellulose) and a secondary wall (hemicellulose or pectin), and is a  simple, living, primarily mechanical tissue of the plant body?

1. Parenchyma

2. Collenchyma

3. Sclerenchyma

4. Aerenchyma

Collenchyma is characterised by

1. Absence of protoplast at maturity

2. Supporting young stem and leaf petiole

3. Lignocellulosic thickening on secondary walls

4. The common presence of intracellular spaces

Lignin is a component of the secondary walls of:-

1. Epidermis

2. Collenchyma

3. Sclerenchyma

4. Parenchyma
