Detailed explanation-1: -Parenchyma is a simple permanent living tissue that is made up of thin-walled similar isodiametric cells. They may be oval, rounded, or polygonal in outline. The cell wall is made up of cellulose.

Detailed explanation-2: -Additionally, permanent tissues are divided into two categories: simple tissues and complex tissue. Complete answer:The tissues are the group of cells that are common in origin and generally perform a common and integrated function. Simple tissues are made up of a single and similar type of cell.

Detailed explanation-3: -Parenchyma is a type of simple permanent tissue that makes a major part of ground tissues in plants, where other tissues like vascular tissues are embedded. They are non-vascular and composed of simple, living and undifferentiated cells, which are modified to perform various functions.

Detailed explanation-4: -Answer: Permanent tissues are made of meristematic cells, that has definite form and shape and have lost the power to divide and differentiate and are of three types-simple, complex and special. The simple tissues are parenchyma, sclerenchyma and collenchyma. Chlorenchyma is a parenchyma, having chloroplast.

Detailed explanation-5: -Parenchyma cells are simple permanent tissues made up of same type of cells, non specific, living cells with intercellular spaces in between. Xylem and phloem tissues are complex tissue composed of different types of cells, which function as a single unit.
