☆Answer:-
A tissue, in biology, is defined as a group of cells that possess a similar structure and perform a specific function. The word tissue originates from French, which means “to weave.”
●Types of tissue:
•In animals, there are 4 types of tissues, namely:-
Muscle tissue (cardiac, skeletal and smooth muscle tissues).
Connective tissue (cartilage, blood, bone).
Nervous tissue (neurons and neuroglia).
Epithelial tissue (simple epithelium, simple cuboidal, simple columnar epithelium, etc).q
•Plants have their own set of tissues, namely:-
Dermal Tissues (epidermal cells, stomata, trichomes).
Ground tissues (Collenchyma, parenchyma, sclerenchyma).
Vascular tissue (Vessel elements, tracheids, companion cells and sieve tubes).
●Concept of Tissues:
The concept of tissues can be traced back to 1801 when it was introduced by Xavier Bichat, a French anatomist and pathologist. He had proposed that tissues are a central element in human anatomy, concluding that organs are essentially a collection of distinct tissues.
