The term tissue is used to describe a group of cells found together in the body. … Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous.

What is Cell Class 9?

“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.” Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.

How is tissue formed?

Tissues are formed from the assemblage of cells and intercellular materials in various proportions in which one component predominates. In nervous tissue as an example, nerve cells predominate while in connective tissues such as Ligaments and Tendons, intercellular fibrous materials predominate.
