The three main types of simple tissues are parenchyma, collenchyma, and sclerenchyma. These tissues are characterized by being composed of only one type of cell.
Here’s a brief description of each:
Parenchyma:
This is the most abundant type of tissue in plants and is involved in various functions like photosynthesis, storage, and wound healing.
Collenchyma:
This tissue provides flexible support to young plant parts and is characterized by its thick, unevenly thickened cell walls.
Sclerenchyma:
This tissue provides rigidity and support to mature plant parts, with cells often having heavily thickened, lignified walls and can be dead at maturity
