Plant Tissues
* Tissues are a group of cells similar in structure and functions.
* Plant tissues include meristematic and permanent tissues.
* Permanent tissues often form protective covering in the form of epidermis and cork.
* Permanent tissues are of two types: simple and complex.
* Simple tissues include parenchyma, collenchymas and sclerenchyma.
* Complex tissues include xylem and phloem.
Animal Tissues
* Animal tissues are epithelial, connective, muscular and nervous tissues.
* Epithelial tissues are squamous, columnar, cuboidal, ciliated and stratified tissues.
* Connective tissues are fluid, areolar, adipose, fibrous, cartilage and bone.
* Muscular tissues are striated, unstriated and cardiac tissues.
* Nervous tissues consist of neurons that transmit information throughout the body.
