Question 8

Which of the following information provides the strongest evidence to support the evolutionary relatedness between fungi and animals?

Accepted Answer

A)  They both possess a cell wall made of chitin.
B)  Both are heterotrophic.
C)  Molecular data shows a similarity in DNA/RNA base sequences.
D)  Some fungi and animals have flagella.

Question 9

Fungi were once classified as plants,but molecular data has shown that fungi are more closely related to animals than plants.Compare and contrast fungi to both plants and animals.

Accepted Answer

Answers may vary.Fungi were once classified as plants because they are nonmotile and their cells have cell walls.Upon closer examination,we find that fungal cell walls contain chitin,whereas plant cells walls contain mostly cellulose.Both are polymers of glucose,but chitin has nitrogen groups attached to the glucose molecules.Unlike plants,which are photoautotrophs,fungi are heterotrophic like animals.In contrast to animals that are heterotrophic by ingestion,fungi are heterotrophic by absorption.They secrete enzymes,which digest organic molecules externally.The fungus then absorbs the smaller molecules.Most fungi,like plants,are nonmotile.An exception are the chytrids which have a motile zoospore.It is believed that animals and fungi evolved from a flagellated protist.

Question 10

Batrachochytrium dendrobatidis,which reproduces asexually through the production of zoospores,recently destroyed populations of harlequin frogs in Central and South America.It is a member of which phylum of fungi?

Accepted Answer

A)  Zygomycota
B)  Chytridiomycota
C)  Basidiomycota
D)  Glomeromycota

Question 11

Which of the fungal groups is mismatched with the asexual spore produced?

Accepted Answer

A)  Ascomycota-conidiospores
B)  Zygomycota-sporangiospores
C)  Chytridiomycota-zoospores
D)  None are mismatched.They are all correctly matched.

Question 12

Fungal diseases include all of the following EXCEPT

Accepted Answer

A)  oral thrush.
B)  strep throat (pharyngitis) .
C)  athlete's foot.
D)  ringworm.

Question 13

Question 14

Dikaryotic cells of fungi

Accepted Answer

A)  are just another form of haploid cells.
B)  is just another name for diploid cells.
C)  contain paired haploid nuclei that fail to fuse for an extended period of time.
D)  are nonseptate plasmodial masses with many nuclei and no cell partitioning.
E)  are potential symbionts that can join with algae to form lichens.

Question 15

Which of the following statements describes mycorrhizae?

Accepted Answer

A)  A mycorrhiza is a mutualistic relationship between fungi and the roots of most plants.
B)  A mycorrhiza is a mutualistic relationship between bacteria and the roots of most plants.
C)  A mycorrhiza is a parasitic relationship between bacteria and the roots of most plants.
D)  None of these statements describes a mycorrhiza.

Accepted Answer

A) True 
 B)False

Question 18

Arbuscular mycorrhizal fungi invade plant roots,with many species forming mutualistic associations that benefit both the fungus and the plant.

Accepted Answer

A) True 
 B)False

Question 19
