Question

Simple tissue is defined as
A. Group is similar cells which are common in origin
B. Different types of cells performing the same functions
C. Different types of cells performing different functions
D. Organised group of cells performing many functions

Answer 1

Hint:Most tissues in the human body are permanent tissues, these are the tissues that have lost their ability to divide. 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. Some simple tissues in plants include parenchyma, collenchyma, and sclerenchyma.
Simple tissues are the tissues that comprise cells which are structurally and functionally similar, that is, they are made up of only a single type of cell.
Some types of simple tissues in plants are:
1. Parenchyma
2. Collenchyma
3. Sclerenchyma
So, the correct option is A) Group is similar cells which are common in origin


Additional Information:

Type of tissue	Cell types	Function	Location of the tissue
Simple tissue	Parenchyma	Photosynthesis, healing of wounds, food and waste storage	In xylem and phloem; stem cortex and pith, root cortex and leaf mesophyll
Simple tissue	Collenchyma	Support the growing plant parts	Stem cortex and leaf petiole
Simple tissue	FibersSclereid	Support and Protections	In xylem and phloem, in leaves, in fruit, seed coats, and stem cortex

Note:If the tissues contain functionally and structurally similar cells, then they are known as simple tissues. If the tissues contain more than one type of cell and perform integrated functions together as a unit, carrying out multiple functions, then they are known as complex tissues. Some differences between simple and complex tissues:

Simple tissues	Complex tissues
They contain one type of cells only	These tissues contain more than one type of cell
Cells carry out the same function	Cells can carry out different functions
Examples are: Parenchyma, collenchyma, and sclerenchyma	An example is: Phloem and xylem
