The development of the zygote into a young embryo within the female gametophyte is a characteristic of:
Seed plants
Seedless vascular plants
Bryophytes
Green algae
From an evolutionary perspective, the retention of the female gametophyte with a developing young embryo on the parent sporophyte offers what primary advantage?
Enhanced embryo protection and nutrition
Increased spore dispersal efficiency
Improved gamete fusion rates
Reduced dependence on water for fertilization
In which plant group is the retention of the female gametophyte with the developing embryo on the parent sporophyte first observed as a significant evolutionary step?
Bryophytes
Heterosporous vascular plants
Gymnosperms
Green algae
The evolutionary adaptation of retaining the female gametophyte on the parent sporophyte is a precursor to which significant development in plant reproduction?
Spore dispersal
Vegetative propagation
Seed habit
Double fertilization
Unlike its predecessors, the retention of the female gametophyte on the parent sporophyte allows for:
Increased spore production
Enhanced photosynthesis
Reduced reliance on water for fertilization
Improved dispersal of spores
The positive evidence of aquatic ancestory of bryophytes is indicated by
Ciliated sperms
Gametophytic body
Biflagellate gametes
Peristomial teeth
Which green alga shows heterotrichous habit and may have given rise to terrestrial (land) habit?
Chlamydomonas
Fritschiella
Vaucheria
Ulothrix
Tracheids
Are the dominant cell types of xylem in angiosperms
Are primarily found in mosses and liverworts
Are responsible for water conduction and support in many land plants
First appeared during Palaeozoic era
Angiosperms have dominated the land flora primarily because of their
Power of adaptability in diverse habitat
Property of producing large number of seeds
Nature of some pollination
Domestication by man
