BOTANY 1 LAB EXAM 2 REVIEW GUIDE

 


TOPIC 8: MEIOSIS

 


TOPIC 10: PROKARYOTES

 


TOPIC 13: THE FUNGI


 


Topic 13 Protista II:  Heterokonts and Green Algae

1.  Know the the phyla (Oomycota, Bacillariophyta, Phaeophyta, Chlorophyta) and these examples:

Phylum: Oomycota

 Saprolegnia (the water mold)

Phylum: Bacilliariophyta

  diatoms

Phylum: Phaeophyta

 Laminaria, Macrocystis, Fucus, Sargassum

Phylum: Chlorophyta

  Class:  Chlorophyceae

  Chlamydomonas, Volvox, Hydrodictyon, Oedogonium, Fritschiella

 

 Class: Ulvophyceae

  Ulothrix, Cladophora,Ulva, Codium

 

 Class:  Charophyceae

   Spirogyra, Chara

2.  Understand what a heterokont is and what phyla are considered heterokont phyla.

3.  Know the structures of the water mold Saprolegnia: hyphae, mycelium, sporangia, zoosporangia, oogonia, eggs, antheridia, oospores.  Understand which structures and haploid and diploid.

4.  Understand what makes the diatoms different than the other phyla.

5.  What is a pennate and a centric diatom and in what habitat would you most likely find each?

6.  What is the the overlapping cell walls of the diatom called?  What is it composed of?

7.  What is the difference between kelps and rockweeds?  Be able to identify examples and kelps and rockweeds.

8.  Know these structures of a kelp: holdfast, stipe, blade, air bladders.  If you cut the body of a kelp, what two layers most noticeable?

9.  Know the life cylce of Fucus?

10.  Know these structure of Fucus: receptacles, conceptacles, air bladders.  What is the function of air bladders?

11.  Understand what Sargassum is and what the name means.  What is the Sargasso sea?

12.  What is the Volvocine line and how does Chlamydomonas  and Volvox  fit into the scheme?  What are daughter colonies?

13.  Using the terms motile/nonmotile, unicellular/colonial, filamentous/parenchymatous, characterize the different green algae (example = Volvox  is a motile colonial form).

14.  Define:  isogamous, anisogamous, oogamous.

15.  What is intercalary growth?  What are annular scars?  Where do we (what alga) find these structures?

16.  Identify these structures:  conjugation tube, isogamete, zygote, zygospore.  Is a zygospore haploid or diploid?

17.  Identify the complex gametangia (an oogonium and an anteridium) on Chara.

18.  Identify Ulva.  What type of life cycle does Ulva have?  Be able to identify and classify Codium to class from the herbarium mount.

SUMMARY OF LIFE CYCLES TO KNOW FOR LAB EXAM 2

1. Zygomycota: Rhizopus - zygotic meiosis life cycle

2. Ascomycota: typical ascomycete - zygotic meiosis life cycle

3. Basidiomycota: life cycle of mushroom - zygotic meiosis life cycle

4.  Puccina graminis (wheat rust) as presented in lab handout.

5. Myxomycota: typical myxomycete - modified gametic meiosis life cycle

6. Phaeophyta: Fucus - gametic meiosis

7. Chlorophyta: Ulva - sporic (alternation of isomorphic generations)

8. Oomycota: Saprolegnia - gametic
