Q

Alternation of Generations

A

members of a species exist in two body forms, one
sexual and one asexual. Alternation of generations is seen in some red and green algae
and all higher plants.

A

small nonvascular plants found on soil, trees
gametophyte is dominant
Bryophyta Clade

22
Q

Tracheophyta Clade

A

plants, have tubes of vascular tissue (xylem and phloem)
extending from their true roots, up their true stems and to their true leaves.

23
Q

Seedless vascular plants

A

produce spores enveloped
in sporopollenin. do not produce seeds
sperm is flagellated
water for fertilization.
sporophyte generation
dominant,

24
Q

Moniliophyta (Polypodiophyta) Clade

A

diverse group of ferns. cold to warm, and wet to dry.
true roots, stems and leaves.

25
What is a gametophyte
the haploid phase of a plant's life cycle that produces gametes (sperm and eggs) for sexual reproduction
26
What is a sporophyte
diploid phase of a plant's life cycle that produces haploid spores through meiosis, which grow into the gametophyte generation
27
oogonium
female reproductive cell that develops into an egg cell (ovum) in plants, algae, fungi, and animals
28
antheridium
male reproductive structure in plants, algae, and fungi that produces and releases sperm cells.
29
Volvox
Chlorophytes reproduce asexual colonies
30
Ulva
Chlorophytes Thin, flat body form is called a thallus Multicellular ISOGAMY
31
Oedogonium
Chlorophytes Multicellular, filamentous green alga Oogamous
32
Charophytes
Sister taxa to plants
33
Derived Traits that Separate Plants from Charophytes
Gametangia Alternation of heteromorphic generations Meristems * Embryos * Spores * Stomata Cuticle games suffolk county
34
Gametophyte generation
haploid (n) multicellular; makes haploid gametes by mitosis; gametes that unite to form a diploid (2n) zygote
35
Sporophyte generation
diploid (2n) multicellular; grows from the zygote; makes haploid (n) spores by meiosis that germinate into a new gametophyte.
36
What is the clade of all plants with vascular tissue
Tracheophytes
36
Xylem
water and minerals from soil up to the rest of the plant
37
Phloem
products of photosynthesis (throughout the plant.
38
Characteristics of Ferns
possess homospory do NOT produce seeds. - sperm is flagellated
