Seeds vary greatly in size from that of the dust-like orchid and begonia to that of Seychelles cocoanuts, which sometimes ^veigh 40 pounds, and are 18 inches in girth. 12. The micropyle is a minute opening through the seed coats. Through it the pollen tube enters the ovule and- the radicle emerges during the process of germina- tion. Often it is almost invisible until the seeds begin to.
