A group of cells performing a particular function is called a tissue.
The function of a cell
A cell is the structural and functional unit of life. Each cell contains smaller organelles that perform various functions such as metabolism, transportation and secretion of substances.
- They provide structure and support.
- Facilitate growth through mitosis
- Cells import nutrients to use in the various chemical processes that go on inside them.
- They produce energy
- Cells that perform the same functions combine to form body tissues, such as skin, muscle and bone tissue.
Tissue
Tissue is a group of cells that have a similar structure and that function together as a unit.
- There are four different types of tissues in animals: connective, muscle, nervous, and epithelial.
- In plants, tissues are divided into three types: vascular, ground, and epidermal.
- Groups of tissues make up organs in the body, such as the brain and heart.
