e) In the fungus C
Label.
D - Zygosporangium
E- Gametangia
7. What is the common name of the photosynthetic organism in front of you? Lichen
How many of organisms are there in each specimen? What are they? Two; Algae + fungi (Ascomycota,
Basidiomycota)
What type of relationship are there (e.g parasitic, symbiosis, friendship, enemies,….etc)? Mutualism
What types of growth form are in A, B, & C?
A: Fruticose
B: Crustose
C: Fruticose
D: Foliose
8. You are looking at one of specimen of question 7. What is the name of layer in the black or purple dot?
Algal layer
9. The left sides are come from roots of a plant. What is the relationship presented? Explain in detail
(e.g. things that they give and take each other.) Symbiosis (mutualism); The plant provides fungi with
nutrient(carbohydrates). The fungi help the plant to obtain nitrogen and protect the plant from pathogen.
Give the name in each slide.(hint, one is present outside and the other inside.)
A: Endomycorrhiza
B: Ectomycorrhiza
What is the difference between A and B?
A - Fungal hyphae penetrate the plant cell wall in root.
B – Fungi wrap outside root.
10. a) Kingdom – Protist
Phylum – Oomycota
Genus – Saprolegnia
b) Label.
A: Antheridium B- Antheridium C- Oogonium D-Egg E- oogonial stalk
(middle circle one – Oospore or zygote (after fertilization) G - Hypae
c) Sexual or Asexual Sexual
d) If this is sexual, how do they fertilize to make zygotes? If this is asexual, how do they replicate?
Sperm migrate toward the egg cell through a fertilization tube sperm fertilization tube.
