Tissues are a group of cells that combine together to perform a particular function. There are four main types of tissues in animals: epithelial, connective, muscular, and nervous. In plants, there are two types of tissues: meristematic and permanent. Permanent tissues arise from the meristematic tissue and have structural and functional properties. Permanent tissue can be made up of either living or dead cells and is specialized to perform a specific function, such as parenchyma, collenchyma, xylem, phloem, etc. .
