Solution – Simple Tissues are made up of cells that are physically and functionally similar, meaning they are made up of only one type of cell while Complex tissues are those that are made up of multiple types of cells that work together as a unit. The complex tissues are responsible for transporting organic material, water, and minerals up and down the plant. As a result, they’re also called Conducting and Vascular Tissues.
There are three types of Simple tissues –
Parenchyma
Collenchyma
Sclerenchyma
Parenchyma are live, walled cells that are soft due to the presence of thin-walled cells. Collenchyma are live cells with an irregular thickness to their walls. This unequal cell wall thickness divides partially hard, providing mechanical support coming primarily from the elongated cells of the ground meristems, and occasionally procambium.
Sclerenchyma cells have thickened lignified walls that give strength and waterproofness.
Complex tissues are of two types –
Xylem
Phloem
The basic distinction between simple and complicated tissue is that simple tissue has just one type of cell, whereas complex tissue contains a variety of cell types. Epithelium is a simple tissue in animals, whereas Epidermis is a simple tissue in plants. To hold all of the organs together and maintain them, complex tissues are strewn across the body.
