Question

. In the space to the right of each group write NV for non-vascular or SL for seedless vascular (1 point each). List the characteristics of the sporophytes in your drawings. In particular, note a) their colors and sizes of sporophytes b) the location and colors of the sporangia; c) the presence or absence of stomata; and d) type dependency between the sporophyte and gametophyte—explained. (total 60 points)

group (NV or SL?)	a (2 points each)	b (2 points each)	c (2 points each)	d (3 points each)
mosses
liverworts
hornworts
whisk ferns
ground pine
ferns

Answer 1

GROUPS	NV/V	SPOROPHYTE FEATURES	SPORANGIA FEATURES	STOMATA ?	DEPENDENCY
Mosses	Non-vascular	Found in the archegonial venter,contains seta and operculum	Found on long, unbranched stems	Have stomata on the sporangia	Dominant generation is haploid and is the sporophyte
Liverworts	Non-vascular	Present in the archegonium,develops to have foot,seta and capsule	Have unbranched sporangia	Do not have stomata	Dominant generation is dipoid and is the gametophyte
Hornworts	Non-vascular	Grows from the meristem base and develops in the deep embedded archaegonia	Have sporangia with central collumela	Have true stomata on the sporangia	Dominant generation is dipoid and is the gametophyte
Whisk ferns	Vascular	Asexual and larger in size that produce the spores	Present in the green stems and make up the synangia	Have stomata on the stem surface	Dominant generation is dipoid and is the gametophyte
Ground pine	Vascular	Diploid in nature and matured	Are kidney shaped or reniform in nature and contains homospores	Have stomata on the pine needles	Dominant generation is dipoid and is the gametophyte
Ferns	Vascular	Free-living and branched in nature	Found on abaxial surface and are clustered and also maybe on the leaf margins	Have stomata on the lower surface of the leaves	Dominant generation is haploid and is the sporophyte
