PLANT TISSUES CELLS that work with other cells for a COMMON FUNCTION form TISSUES MERISTEMATIC Apical Lateral PERMANENT Interecalary COMPLEX SIMPLE Parenchyma Vascular Collenchyma Xylem Schlerenchyma Phloem DERMAL Epidermis Cork & Cork Cambium
MERISTEMATIC TISSUES APICAL – growth in length
MERISTEMATIC TISSUES LATERAL – growth in width or girth
MERISTEMATIC TISSUES INTERCALARY – growth from the base of nodes
MERISTEMATIC TISSUES Undifferentiated cells undergoing ACTIVE GROWTH
PERMANENT TISSUES SIMPLE – contain only one type of cell Parenchyma Collenchyma Sclerenchyma
PERMANENT TISSUES COMPLEX – two or more different types of cells VASCULAR tissues XYLEM – conducts WATER PHLOEM – conducts FOOD DERMAL tissues EPIDERMIS – single cell layer CORK & CORK CAMBIUM Meristem and outer bark of woody plants
