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
Solution
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 |
