Which eukaryotic clade (i.e. supergroup) includes the fungi? |
Opisthokont |
|
A unicellular fungus is called a(n): |
Yeast |
|
A multicellular fungus is called a(n): |
Mold |
|
The body of a multicellular fungus is composed of tubes of cytoplasm called: that form a cottony mass called a(n): |
Hyphae Mycelium |
|
A mycelium that is not subdivided into cells is described as being: |
Coenocytic |
|
Most fungi have a zygotic life cycle, so the only diploid stage in the life cycle is the: |
Zygote |
|
What is a dikaryotic cell? |
N+N 2 genetically distinct nuclei |
|
Which two fungal phyla form dikaryotic hyphae? |
Ascomycota Basidiomycota |
|
Fungi have cell walls formed (in part) from the structural carbohydrate: |
Chitin |
|
Which fungal phylum consists of unicellular obligate parasites of animals that reproduce by forming spores? |
Microsporidia |
|
Which phylum includes the black bread molds (e.g. Rhizopus)? |
Zygomycota |
|
List the three phyla that include aquatic fungi that form flagellated cells: |
Chytridiomycota Blastocladiomycota Neocallimastigomycota |
|
Which of the three groups listed in the previous question contains obligate mutualists found in rumens of herbivores? |
Neocallimastigomycota |
|
The sexual spores formed by black bread molds (e.g. Rhizopus) are called: |
Zygospores |
|
Hyphae, such as those of black bread molds (and many other molds), that are not septate (i.e. divided into cells) are described as being: |
Coenocytic |
|
Members of the phylum Glomeromycota are root symbionts with vascular plants. These mutualistic associations are called: |
VAM |
|
Many members of the Ascomycota commonly reproduce asexually by pinching off cells from the tips of hyphae. These reproductive cells are called: |
Ascospores |
|
Sexual spores are formed by ascomycete fungi within sac-like cells called: |
Ascus |
|
Sexual spores are formed by basidiomycete fungi at the tips of club-like cells called: |
Basidia |
|
Both ascomycete and basidiomycete fungi form septate reproductive hyphae whose cells each contain two nuclei of different mating types. These hyphae are described as being: |
Dikaryotic |
|
A lichen is a mutualistic relationship formed by a(n): |
Fungus Unicellular Alga |
|
The fungal portion of most lichens is classified in the phylum: |
Ascomycete |
|
The photoautotrophic portion of a lichen is usually a(n): or a(n): |
Green alga Cyanobacterium |
|
Which eukaryotic supergroup includes the animals? |
Opisthokont |
|
During early embryonic development, most animals form an archenteron, whose only connection to the outside is by an opening called the: |
Blastopore |
|
Which three germ layers are present in a triploblastic animal? |
Ectoderm Mesoderm Endoderm |
|
An animal that has a body cavity that is only partially lined with mesoderm is described as being: |
Pseudocoelomate |
|
Briefly distinguish between bilateral symmetry and radial symmetry: |
Bilateral- has a head |
|
Briefly distinguish between protostomic development and deuterostomic development: |
Protostomic- blastopore becomes the mouth Deuterostomic- blastopore becomes the anus |
|
Which animal phylum lacks symmetry, germ layers, and true tissues/organs? |
Porifera |
|
Which animal phylum has radial symmetry? |
Cnidarians |
|
Cnidarians often have a life cycle that includes a swimming stage called the: and a non-motile, sedentary stage called the: |
Medusa Polyp |
|
The “nervous system” a cnidarian consists a dispersed system of nervous tissue called a(n): |
Nerve Net |
|
Which phylum includes tapeworms, flukes, and planarians? |
Platyhelminthes |
|
Flatworms lack a respiratory system. How do flatworms accomplish gas exchange? |
Flat body= easy gas exchange though diffusion |
|
Rotifers have an anterior ciliated structure called the: |
Corona |
|
Which phylum includes colonial lophophorate animals that lack circulatory, respiratory, and excretory systems? |
Bryozoa |

|
In some “soft-bodied” animals, such as roundworms or segmented worms, muscles contract against a rigid, fluid-filled body compartment(s). This type of skeleton is called a(n): |
Hydrostatic |
