concept 6.7: extra cellular components are connections between cells help coordinate cellular activities

what are some extra cellular structure s

cell walls of plants, the extracellular matrix and intercellular junctions

cell wall

protects the plant cell, maintains its shape and prevents excessive uptake of water

what is cellulose synthase

protein that produces cellulose fibers fthat are secretes and embedded in polysaccharides and proteins outside the cell

extracellular matrix of animal cellls

made of glycoproteins liek collagen, proteoglycans and fibronectin and they support the cell attached to it and allow rthe cell to adhere

plasmodesmata

channels that traverse across the cell wall to connect adjacent plant cells and allows water and small solutes like proteins and RNA to pass from cell to cell

what are junctions

allows cells to press together or interact closely with one another
