Document Summary
Monocot vs. dicot (one seed leaf vs. two seed leaves) Corn: endosperm within it consists of starch (a polysaccharide of sugars: there for the developing embryonic plant, not us) Seed imbibes and enzymes within seed coat turn on and break down starch into glucose used to make atp used to drive production of rot and shoot system. In most monocots: 1st seed leaf never leaves root. 1st structure to leave ground and shoot up = coleoptile (structure of first leaves; when it opens . 1st photosynthetic organ of plant: developing embryo in chicken: yolk used as nutrients for egg (endosperm in monocots serve a similar purpose, after endosperm is depleted, embryo is dependent on autotrophic growth. In most: no endosperm remaining in fully mature seed; instead 2 cotyledons (containing the 2 seed leafs that will be 1st used for photosynthesis)
