Answer 2

Simple permanent tissues are made up of cells with comparable structures and functions that come from the same source. They're also known as homogeneous tissues, and they come in three different forms.

Explanation:

• Collenchyma is a living tissue made composed of cellulose, water, and pectin, and it has a thick cell wall. The cells in collenchyma tissues are densely packed, resulting in a small amount of intracellular space. Collenchyma tissue has the highest refractive index due to the presence of pectin. It has a lower chlorophyll content. It's primarily present in the hypodermis of dicot leaves and stems. It's not found in the roots of plants, and it's also not found in monocots. Mechanical strength, elasticity, and tensile strength are provided by these tissues to the plant body.
• Sclerenchyma tissue is made up of dead cells with a strong cell wall and a little amount of protoplasm. These tissues have a strong secondary cell wall that secretes lignin, which gives mechanical support to the plants. Intramolecular gap between the cells is completely absent. It is impervious to water because of its thick and strong lignin-based outer cell walls.
