2.2 plant tissuesSudarshana ElapathaThis document discusses plant tissues and their functions. It explains that there are three main types of plant tissues - meristematic tissue, permanent tissue and vascular tissue. Meristematic tissue is responsible for cell division and growth. There are three types of meristems - apical, lateral and intercalary. Permanent tissues include simple tissues like parenchyma, collenchyma and sclerenchyma and complex tissues like xylem and phloem. Xylem transports water and minerals while phloem transports food. Dermal tissues like epidermis and peridermis protect the plant from water loss and pathogens. In woody plants, the peridermis is formed from the cork cambium.
