Q

Plants are Eukaryotic or prokaryotic?
What is contained in their cell walls?

A

Eukaryotic
Cellulose

20
Q

Explain General seedless plant life cycle

A

Goes through a MULTICELLULAR haploid stage called gametophyte into a MULTICELLULAR diploid stage called sporophyte.

21
Q

Is gametophyte and sporophyte structures or life cycle stages?

22
Q

What does the gametophyte stage produce?

23
Q

What are the gametes called in a seedless plant lifecycle?

A

Female archegonia (egg)
Male antheridia (sperm)

24
Q

Explain the gamete cellular structure

A

Both are single celled haploid

25
What life cycle is the zygote and what is it’s cellular structure?
Diploid single celled
26
What is the sporophyte?
Multi cellular diploid stage
27
Explain the Sporophyte stage
Cells in sporangium undergo meiosis to release spores (single cell haploid)
28
What are four major groups of plants?
Bryophytes Seedless vascular plants Gymnosperms Angiosperms
29
types of Bryophytes (non-vascular)
Mosses, liverworts, hornworts
30
Type of seedless vascular plants
Ferns
31
What are gymnosperms
Plants with seeds on scale like structures called cones
32
What are Angiosperms
Flowering plants
33
What stage is dominant in non vascular plants?
Gametophyte stage
34
Explain asexual reproduction in liverworts:
They contain Gemma cups on the thallus that have gemmae that are washed out of the cups by rain water to spread.
35
How do liverworts produce sexually?
Reproductive structures grow on the thallus. The Antheridiophores contain antheridia that produce sperm and swim to the genial archegoniophore. They fertilize creating the zygote that developed into the diploid sporophyte.
36
What happens in liverworts after the sporophyte stage?
The sporophyte produces spores that release and grow into the new thallus.
37
What is unique about hornworts? Hint* energy
They have a photosynthetic sporophyte
38
Explain the prothallium
Heart, Archegonium in the top Sides, antheridium and the bottom “roots” is the rhizoids
39
Name a type of liverwort
Marchantia
40
What is the visible part of the fern sorus?
The indusium
41
What is the “flowering” part of the horsetail called?
The Strobilus
42
Where do the leaves on a fern plant?
On the stem nodes
43
What does the Strobilus produce?
Spores
