Chapter 20, Problem 1MCQ

Summary Introduction

Introduction:

The molecular phylogeny is the main basis of the evolution of the fungal taxonomy. The classification systems are based on the evolutionary relationships between the groups and the classification is named as phylogenetic classification.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

The most similar type of organism with the ancestral fungus is a chytrid. Therefore, option (d) is correct.

Explanation of Solution

Reason for the correct statement:

The ancestral fungus evolved into Chytridiomycetes first. Some of the Zygomycetes and Chytridiomycetes share a common ancestor. However, the Chytridiomycetes are closest to the ancestral fungus because of the similarities in the DNA (deoxyribonucleic acid) sequences.

Option (d) is given as “A chytrid”.

As, “the chytrids have the most similarities with the ancestral fungus because of the similarities in the DNA sequences”, is the right answer.

Hence, option (d) is correct.

Reasons for the incorrect statements:

Option (a), is given as “A bacterium”.

The bacteria are placed in the kingdom Monera and not fungi. Their evolution was different from fungus. Hence, it is a wrong answer.

Option (b), is given as “A plant”.

The plants belong to the kingdom Plantae and not fungi and the plants are more evolved than fungi. Hence, it is a wrong answer.

Option (c), is given as “A basidiomycete”.

The Basidiomycetes are considered as the most evolved fungi and hence they share very less similarities with the ancestral fungus. Hence, it is a wrong answer.

Hence, options (a), (b), and (c), are incorrect.

Conclusion

According to the DNA sequencing data, the Chytridiomycetes are considered as the most primitive types of fungi and the Basidiomycetes and Ascomycetes share a common ancestor and are more evolved than other phyla of fungi.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)
