Where does the diploid portion of the haplodiplontic life cycle occur?
|
in the sporophyte
|
|
sporophyte
|
(in the life cycle of plants with alternating generations) the asexual and usually diploid phase, producing spores from which the gametophyte arises. It is the dominant form in vascular plants, e.g., the frond of a fern.
|
|
gametophyte
|
(in the life cycle of plants with alternating generations) the gamete-producing and usually haploid phase, producing the zygote from which the sporophyte arises.
Dominant in nonvascular plants (Bryophytes) |
|
Nonvascular plants
|
do not have zylem & phloem
-still must live in moist environments -sperm flagellated and must swim to egg -gametophyte dominant (green part of moss) |
|
Which plants were first to evolve seeds?
|
gymnosperms
|
|
Animals with radial symmetry
|
Cnidaria
|
|
pseudocoelomates
|
animals with 3 layered body with fluid filled body cavity between endoderm and mesoderm
|
|
defining characteristic of phylum porifera
|
they lack true tissues and they only have intracellular digestion
|
|
protostomes
|
animals where the first opening in development becomes the mouth
|
|
deuterostomes
|
first opening in development becomes the anus
|
|
fertilizers are important because they add these nutrients to the soil:
|
nitrogen, phosphorus and iron
|
|
serosa
|
part of the mammalian digestive system
-anchors organs to body cavity |
|
mucosa
|
lubricates, protects tissue in digestive system, inner most layer
|
|
submucosa
|
between muscularis and mucosa
|
|
muscularis
|
transverse and longitudinal tissues between serosa and submucosa
|
