-Antheridia(containing sperm)in liverworts,
-Genus Marchantia*
-Kingdom Plantae
-Domain Eukarya
Note: Antheridia produce "flagellated sperms" to be more specific -
What is structure on no.2? What is it containing? - Archegonium(liverworts' organism that produce eggs), containing eggs
-
What is structure on No.1 that looks like mushroom called? Is it Male or Female gametophyte -
Antheridiophore(liverworts), male gametophyte because it contains Antheridium -> Antheridia-> flagellated sperms -
What is the structure No.1 called? (liverworts) -
Archegoniophore*-look like palm tree*. -
what is this structure called? - Mature Sporophyte(liverworts)
-
What is this spore production called? -
Homosporous
(most ferns are Homosporous) -
what is this spore production type? -
Heterosporous
(ALL seed plants and a few seedless vascular plant are heterosporous) -
what is the elaters(2n) labeled on No.4? - Cork screw shape cells that are responsible for dispersing spores in the liverworts
-
What is the round structure in this picture? And What is its function? -
Gemmae cups containing Gemmae. It can mitosis to become liverworts
(Asexual reproduction)
it's haploid because it becomes liverworts(n) by mitosis -
What is Phylum of liverworts?
And what genus that we did in the lab? Is it Vascular or nonvascular plant? -
Phylum Hepatophyta**, Genus Marchantia**,
it's nonvascular(gametophyte is dominant) -
What is the plant in the pic? Is the labeled part Gametophyte or sporophyte? What is the Domain,kingdom, phylum of this plant -
Hornworts, It's sporophyte.
The bottom part on the ground is gametophyte.
Domain-Eukraya

What is this plant's Genus?Phylum?Kingdom?Domain? -
Sporophyte,
- Mosses-> Genus Polytrichum*
Phylum Bryophyta*
Kingdom Plantae
Domain Eukarya -
Is this part of liverworts gametophyte or sporophyte -
gametophyte (liverworts are nonvascular plant-gametophyte is dominant)
-This part is called "Thallus" -
What is the genus of this plant that we observed in the lab? Is this plant nonvascular or vascular -
Genus Polytrichum*,
Phylum Bryophyta,
nonvascular plant. -
What is the structure on No.1? What is it containing? -
Capsule or sporangium. It contains spores -
What is the No.2 structure of this plant(mosses)called? what is its function? -
"Operculum"look like lid.
It will pop off to let spore come out -
This is longtitudial section of antheridial head of the moss.Can u tell where Antheridia is located from No.1-6? -
No.6 it's Antheridium ->Antheridia->spores -
This structure is sectioned of moss. Can u tell me what it is? And what is it containing in No.1? -
Archegonia of moss, containing eggs -
What are No.1 ans No.2 on this slide? -
Moss capsule slide -
What is label number No.1 that looks alike algae called? -
Protonema**, It's immature gametophyte of mosses. It's haploid(n). -
What is the teeth alike structure on No.1 called? And what is the genus of the plant that this structure is belonged to -
Peristome teeth,
This structure is in Mosses and genus " Polytrichum "***
-Phylum Bryophyta
-kingdom Plantae
-Domain Eukarya - What is nonvascular plant? Give the examples of nonvascular plants?
-
known as "Bryophytes"
-gametophyte(n) is dominant
-No xylem or Phloem
-Ex.liverworts(Phylum Hepatophyta,Genus Marchantia)
-Ex.Hornworts (Phylum Anthocerophyta)
-Ex.Mosses(Phylum Bryophyta ,genus Polytrichum)
Other phylums are vascular - What are vascular plants?
-
Plant that have two types of tube:Xylem(conduct water and minerals-down) and Phloem (conduct food or sugar-up)
-Sporophyte(n) is dominant
-Seedless Vascular plant
->Use spores because it has no seed -
What is this plant? Give the name of genus and species? In what phylum?Kingdom?Domain? Is it nonvascular or vascular plant? -
-It is Whisk Fern
-" Psilotum nudum ****"
-Phylum Psilophyta
-Kingdom Plantae
-Domain Eukarya
-"most primitive vascular plant" Because it has no true leave and root -
What is this plant?Can you name its genus and species? Is it in what Phylum? -
-Florida quillwort(common)
-"Isoetes flaccida"
-Phylum Lycophyta
-Kingdom Plantae
-Domain Eukarya
-Seedless Vascular plant -
This slide are section from a plant. Can you indicate the organism of plant that is being pointed.Can you tell what is the plant's genus?its phylum? -
-Sporangia(contains spores)
-Genus Lycopodium(club moss)
-Phylum Lycophyta
-Kingdom Plantae
-Domain Eukarya
-Seedless Vascular plant -
What is this plant from? Give genus and species name. -
-"Selaginella strobilus"
-Phylum Lycophyta
-Kingdom Plantae
-Domain Eukarya
-Seedless Vascular plant -
What is this plant? -
Sellaginella Lycopodium(spike moss)
-Phylum Lycophyta
-Kingdom Plantae
-Domain Eukarya
-Seedless Vascular plant -
What is this plant?
Give the genus and species name? Phylum? -
-Equisetum hyemale***
-It's horsetails or scouring rushed (use to scrub pots and pans)
- Have SiO2(Silica)
-No.1 is stem (photosyn.)
-No.2 is nonphotosyn.leave called leave sheath

What is this plant? What 's its phylum? Is it nonvascular or vascular plant? -
-Holly fern
-Phylum Pterophyta
-seedless vascular plant -
What is the small brown circle structure called? - Sori. Each one is called sorus. One sorus have so many sporangium(contains spores)
-
Can you tell what is this structure? Where is Annulus? What's Annulus'function? -
-Sporangium
(contains spores-No.2)
-Annulus is on NO.3
-When Annulus is dried out,it causes the sporangium to break open exposing the spores to air currents -
What is this heart shape structure called? Is it Gametophyte or sporophyte?What type of spore is it(homosporous or Heterosporous) -
- This photosynthetic structure called
" Prothallus or Prothallium"
-Gametophyte(n)
-Homosporous spore production
(single type of spore)
-Consists of Archegonium(dot-like), Anteridium(snake-like). That's why Prothallus is called a bisexual gametophyte. -
