Answer 2

☆Question:-

What is a tissue? How many types of tissues?

☆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).

•Plants have their own set of tissues, namely:-

• Dermal Tissues (epidermal cells, stomata, trichomes).
• Ground tissues (Collenchyma, parenchyma, sclerenchymaissues).
• Connective tissue (cartilage, blood, bone).
• Nervous tissue (neurons and neuroglia).
• Epithelial tissue (simple epithelium).

●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.
