25.Fungi are classified into three major divisions based mainly on
differences in
(a)reproductive adaptations
(b)composition of the cell wall
(c)mode of nutrition
(d)the presence or absence of a dikaryotic stage
29.All of the following are characteristic of angiosperms EXCEPT
(a)coevolution with animal pollinators
(b)free-living gametophytes
(c)double internal fertilization
(d)pistils
(e)fruit
我觉得29是b因为被子植物不是孢子体显着吗 配子体退化??
