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
