phagocytic cellulose cell wall fruiting bodies plasmodial and cellular slime molds
44
Chlorophyta
multicellular green algea spirogyra ulva (leaf like)
45
Characteristics of Land Plants
waxy cuticle stomata
46
Plant Classification
nonvascular plants (Bryophytes) Seedless Vascular Plants Gymnosperms Angiosperms
47
Alternation of Generation
![Displaying IMG_0328.JPG](https://lh6.googleusercontent.com/LEUYXoJKAILgwDm0DZZL3QW-MnxRb3o4aJIc4L7_vgyyiounfaz3VkfCVAbxmvKIbM2k-qLPyXU=w1576-h679)
48
Alternation of Generations
- sporophyte (diploid) produces spores (haploid) by meiosis - gametophyte (haploid) produces gametes (haploid) by mitosis - gametes (haploid) fuse to form zygote (diploid) which develops into sporophyte
49
Archgonia
produce eggs by mitosis
50
Anteridia
produce sperm by mitosis
51
Non vascular plants
bryophyta (mosses) nonvascular moist environment gametophyte dominant liverworts thallus - plant body rhizoids - roots
52
Vascular Seedless Plants
have microphylls sporophyte dominant horse tails whisk ferns ferns heart shaped gametophyte
53
Vascular Seedless Plants Life Cycle
Homospory-produce one spore which produces gametophytes by mitosis heterospory- megaspores divide by mitosis to produce female gametophyte microspores divide to produce male gametophyte
54
Vascular Seedless Plant Alternation of Generations
- sporangium (2n) on sporophyte (2n) produces spores (n) by meiosis - spores (n) grow into gametophyte (n) - gametophyte produces sperm (n) and egg(n) - fertilization produces new sporophyte (2n)
55
Gymnosperms
flowerless seed bearing plants
56
Angiosperms
flowering plants male gametophyte - pollen grain female gametophyte - embryo sac double fertilization- 2n zygote and 3n endosperm
57
Gymnosperm Land Adaptations
vascular tissure seed that doesnt depart on water
58
Angiosperm Land Adaptations
vascular tissue seeds fruit/flower to attract pollinators
59
Flower Parts
