Which term below is the proposed kingdom that would include embryophytes and charophyceans?
Streptophyta
( Some plant biologists now argue that the boundaries of the plant kingdom (Plantae) should be expanded to include the green algae most closely related to plants—the charophyceans and a few related groups.)
Seedless plants include _____.
bryophytes, ferns, and horsetails
( Seedless plants include nonvascular plants, such as mosses, liverworts, and hornworts, and vascular plants, such as lycophytes, ferns, horsetails, and whisk ferns.)
The closest algal relatives of land plants are _____.
charophyceans
( These green algae and plants share many homologous features.)
In seedless plants, a fertilized egg will develop into _____.
a sporophyte
( The fertilized egg will develop into a sporophyte that releases haploid spores.)
The diploid generation of the plant life cycle always _____.
produces spores
( The diploid generation of the plant life cycle always produces spores.)
All of the following structures may be a part of a bryophyte's life cycle except _____.
megaphylls
( Megaphylls are a type of branched leaf. Bryophytes do not have true leaves.)
Most bryophytes, such as mosses, differ from all other plants in that they _____.
lack vascular tissue
( The bryophytes generally lack vascular tissue, which all other plants have.)
In contrast to bryophytes, in vascular plants the dominant stage of the life cycle is the _____.
sporophyte
( The diploid sporophyte generation is dominant in vascular plants; in bryophytes the haploid gametophyte generation is dominant.)
During the Carboniferous period, forests consisting mainly of ____ produced vast quantities of organic matter, which was buried and later became coal.
ferns and other seedless plants
( These were the dominant plant types of the time.)
Sori can be found in which of the following?
pterophytes
( Sori are the small structures under leaf fronds from which spores are released.)
