Lab Exam 2 - Population Genetics, moss/fern, Angio/Gymnio, fungi Flashcards
Are kingdom plantae prokaryotes/eukaryotes? Unicellular/multicellular? Where do they get energy and carbon?
Eukaryotes Multicellular Photoautotrophic (conduct photosynthesis)
Where did kingdom plantae get the ability to do photosynthesis?
Inherited from green algae (P. Chlorophyta)

Which of these are vascular? Which of these are seed plants?
mosses
ferns
gymnosperms
angiosperms
mosses - nonvascular
ferns - vascular / seedless
gymnosperms - vascular / seedless
angiosperms - vascular / seed plants
What do sporangia do?
Sporangia produce spores
What are the five major groups of gymnosperms?
Ginkogophyta (ginkgoes),
cyadophyta (cyads),
cupressophyta (redwoods, junipers, yews),
Pinophyta (pines, spruces, and firs) and
Gnetophyta (gnetophyes)
Plant life cycles:
What is the plant life cycle called?
What does it refer to?
Alternation of generations means that plants alternate between a multiceullular haploid (n) body form and a multicellular diploid (2n) body form from one generation to the next.
Plant life cycles:
What is the multiceullular haploid body form called?
The gametophyte
Plant life cycles:
What is the multicellular diploid body form called?
The sporophyte
What does the gametophyte produce?
The gametophyte produces gametes (n)
What does the sporophyte form produce?
Spores (n)
Plant life cycles:
Where are gametes made? Be specific re: sperm and eggs
In the gametangia
(sperm made in antheridia; eggs in archegonia)
Plant life cycles:
Where are spores made?
In the sporangia?
Plant life cycles:
What happens to gametes?
Haploid gametes (sperm and egg) undergo fertilization and produce a diploid zygote. That diploid zygote grows into a 2n sporophye.
Plant life cycles:
What happens to haploid spores?
Haploid spores grow directly into an adult gametophyte (n)
What type of cell division does a gametophyte use to make gametes? A sporophyte to make spores?
mitosis
meiosis
Bryophyta:
Are they gametophyte-dominated or sporophyte dominated?
How do sperm get to eggs?
Homosporous or heterosporous?
Gametopyte-dominated
dependent upon water; sperm swim to eggs
homosporous
Describe the bryophte life cycle
Bryophyta:
Where is the capsule? Function?
On the sporangia. Where spores are produced.
Bryophyta: is the male gametophyte haploid or diploid? Sperm?
male gametophyte (which has antheridia, where sperm are made) is n; sperm are n. (mitosis)
