gametophyes produce gametes by

41
Q

Evolutionary shift of plants

A

less dependence on water and larger size

42
Q

why is the evolutionary trend in plants possible

A

vascular tissue

43
Q

what is the result of plant evolutionary trend?

A

sporophytes becoming the dominant generation

44
Q

water to land transition

A

algae to bryophytes

45
Q

non-vascular to vascular transition

A

byrophytes to tracheophytes

46
Q

spore dispersal to seed dispersal

A

seedless to seed

47
Q

do not have vascular tissue, tissue no more than couple of cells thick, water and nutrients travel by osmosis and diffusio

A

non-vascular

48
Q

stems of most plants, made of tube-like, elongated cells which transport the xylem and phloem, evolutionary advantage with increase in height of plans

49
Q

non vascular plants

A

chlorophyta (green algae)
bryophyta (mosses)
hepatophyta (liverworts)
anthocerophyta (hornworts)

50
Q

vascular and seedless plants

A

lycophyta (club mosses)
spenophyta (horsetails)
pterophyta (ferns)

51
Q

vascular with seed *gymnosperms

A

coniferophyta (conifers)
cycadophyta (cycads)
ginkophyta (ginko)
gnetophyta (gnetae)

52
Q

no vascular tissue, no true roots, depend on water for reproduction, smaller, live in dark and damp places

A

non-vascular plants

53
Q

small, non-vascular, gametophyte dominant, needs water for fertilization, often seen growing on hard substrates in moist areas

A

bryophyta (mosses)

54
Q

small, non-vascular, gametophyte dominant, needs water for fertilization

A

hepatophyta (liverworts)

55
Q

have true stems, roots & leaves with vascular tissue, no seeds, most land in moist read (flagellated sperm), but occur in deserts and marshes, both upright and horizontal stems

A

seedless vascular plants

56
Q

vascular dichotomously branched stems, small leaves called microphylls

A

lycophyta: club mosses

57
Q

low complexity; sponges

58
Q

more complex but still simple; jellyfish, corals

A

radial symmetry

59
Q

very complex with designated sides; flatworm

A

bilateral symmetry

60
Q

allow for the gastrovascular cavity to form; bigger elements can be digested

61
Q

skin, nerves

62
Q

results in structures not associated with digestion such as organ systems (worms, humans)

63
Q

without a body cavity, mesoderm fills the space

A

acoelomate

64
Q

with a cavity between endoderm and mesoderm

A

pseudocoelomate

65
Q

with cavity within the mesoderm

66
Q

asymmetrical, no tissue layers, no body cavity, no gastrovascular opening

A

porifera (sponges)

67
Q

radial symmetry, 2 tissue layers (ecto and endoderm), no body cavity, 1 gastrovascular opening

A

cnidaria (jellyfish, hyda, sea anemone)

68
Q

bilateral symmetry, 3 tissue layers, no body cavity, 2 gastrovascular openings

A

platyhelminthes (flatworms/planarian)

69
Q

bilateral symmetry, 3 tissue layers, pseudocoelomate body cavity, 2 gastrovascular opening

A

nematoda (nematodes, roundworms)

70
Q

bilateral symmetry, 3 tissue layers, coelomate body cavity, 2 gastrovascular opening

A

annelida (segmented worms, earthworm)

71
Q

single filament of fungi

72
Q

masses of filament

73
Q

reproductive structure of fungi

A

sexual and asexual

74
Q

diverse - unicellular yeasts, powdery mildew, complex cup fungi
common factor - reproductive body, ascus produces ascospores
asexual reproduction - production conidia Peziza, Sordaria, Penicillin

A

ascomycetes

75
Q

largest and most conspicuous (mushroom, toadstool)
obvious part is only small part of the body
distinguished because of basidiospores
mainly use sexual reproduction, but can use asexual mushroom

A

basidiomycota

76
Q

aquatic, flagellated spores

parasitic or saprobic

A

chytridiomycota

77

terrestial, live on decaying matter or soil
some form mycchorizzae with crops
hyphae are coenocytic
black bread mold

A
