Yes john, you're right. The corn you eat off the cob is also a seed that is
eaten unripe. The sweetness is in the liquid endosperm, just as in a
coconut. When corn's ripe, it's starchy.
Thought the starch was the corn's cotyledon, and the endosperm was enclosed.
Guess Bill Purves thinks that's the wrong anatomy of monocot seeds. I still
want to know where the cotyledon is in a Mono - cotyledonus plant.
