Answers
Answer:
Tissue is a cellular organisational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extra cellular matrix from the same origin that together carry out a specific funtions. There are four types of tissue:
- Muscular tissue
- Connective tissue
- Epithelial tissue
- nervous tissue
Tissue
Tissues are group of cells that have a similar structure and act together to perform a specific function.They are
of two types simple and complex tissues.Simple tissues are made up of cells of same type or kind e.g. glandular tissue and complex tissues are made up of different kind of tissues e.g. tissues of dry skin.Hence,simple tissue is homogeneous and complex tissue is heterogeneous.
Types of Tissues
Depending on the basis of their structure and function, tissues can be classified into four types- Epithelial (covering) tissue for protection, Muscular (contractile) tissue for movements and locomotion, Connective (supporting) tissue for binding different structures of body and Nervous tissue for conduction of nerve impulses.All the complex organisms consist of only four basic types of tissues.
Types of Epithelial Tissues
- Squamous
- Cuboidal
- Columnar
- Ciliated
- Glandular
Types of Connective Tissues
- Areolar
- Tendon
- Ligament
- Adipose
- Skeletal
- Bone
- Cartilage
- Fluid
- Blood
- Lymph
Types of Muscular Tissues
- Striated
- Smooth
- Cardiac
