Either 3n or 5n. 13) A flower that is incomplete can also be perfect (T/F)-True 14) Through what structure does the male gamete reach the female gamete in angiosperms?-Style 15) Based on the four groups, how would you classify plants used to create the leachates?-gymnosperms 16) Of the four groups, which have seeds?-gymno and angiosperms 17) What is the difference between a monocot and dicot? (in terms of seeds)-monocots have one cotyledon, dicots have two cotyledon. 18) What method of cel division produces spores?-meiosis....
