Question

What is the difference between simple permanent tissue and complex permanent tissue? Discuss different types of tissues found in complex permanent tissue.

Answer 1

Hint: Tissues are made up of clusters of cells which work together. In plants, there are three types of tissues- Meristematic tissues, permanent tissues and protective tissues.

Complete answer:

Differentiation Factor	Simple Permanent Tissues	Complex Permanent Tissues
Nature	Homogenous	Heterogenous
Example	Parenchyma, Sclerenchyma, Collenchyma	Xylem and Phloem
Function	Repairs tissues, food storage system, secretion, and structural support	Assists in conducting water and minerals throughout the different body parts
Distribution	Present across every plant part	Principally situated within the vascular regions
Cell Composition	Comprising of single cell type	Comprising of different cell types

The different types of permanent tissues found are,
Simple permanent tissues
>They can be divided into 3 types on the basis of their purpose
>Parenchyma - They are polygonal cells which have intracellular spaces and they create ground tissue and pith
>Sclerenchyma - They are dead cells which have lignin deposits in their cell wall. They provide strength to the plants
>Collenchyma - These cells have very less to no gap between them. They are made up of cellulose and pectin. They provide support, flexibility and structural framework to the plants.

Complex permanent tissues
There are two types under this,
>Xylem - It is made up of xylem fibers, vessels, parenchyma and tracheids
>Phloem - It is made up of phloem fibers, parenchyma, sieve tubes, sieve cells and companion cells

Note:The permanent plant tissues contribute in providing support, protection, photosynthesis, and conducting water and other dissolved minerals throughout the plant body parts.
