monocots - multiples of 3 - parallel veins - fibrous spreading (adventitious) roots all over the place ) - stem cross section is vascular bundles scattered - one monocot in seed
dicots - multiples of 4 or 5 - net(work) of veins - tap root - stem cross section vascular bundles around the edge - 2 monocots in seed
Germination:
•When conditions are just right, dormancy is broken
•Absorption of water through a pore in the testa triggers metabolic changes in the seed - secretion of enzymes that metabolise the stored food (what kind of enzymes?)
–Maltase and amylase break down starch into glucose
–Glucose converted to sucrose for transport
–Proteases break down the protein
–Lipases break down the lipids
