Chapter 29, Problem 1TY
Summary Introduction

Introduction: Microscopic, branched filaments known as hyphae form a distinctive body of fungi known as mycelium. “Fungi are heterotrophic in nature”, and they can grow in soil, a piece of bread and several other materials.

Answer to Problem 1TY

Correct answer: Both fungal and animal cells are eukaryotic in nature. However, the absence of cell walls in the animal cells distinguish them from the fungal cells. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Fungal cells have a rigid layer external to the plasma membrane called cell wall. The cell wall of fungi is made up of chitin and they play role in the protection of cells. This protective layer is absent in animal cells.

Option c. is given as “have chitin-rich cell walls, whereas animal cells lack cell walls”.

The presence of chitin-rich cell walls in the fungal cells differentiates them from the animal cells. Hence, the correct answer is option c.

Reasons for incorrect answer:

Option a. is given as, “lack ribosomes, though these are present in animal cells”.

The cells of fungi are eukaryotic in nature. Therefore, like animal cells, fungi also contain ribosome, a cell organelle. Hence, option a. is incorrect.

Option b. is given as, “lack mitochondria, though these occur in animal cells”.

Cell organelles such as mitochondria are required to provide energy to the cell in the form of ATP molecules and are present in all eukaryotic cells including the animal cells and fungal cells. Hence, option b. is incorrect.

Option d. is given as, “lack cell walls, whereas animal cells possess cell walls”.

Fungal cells have a protective layer in the form of a cell wall, which is mainly composed of chitin. However, animal cells do not have cell walls. The organelles present in the animal cells are enclosed within a phospholipid bilayer known as the plasma membrane. Hence, option d. is incorrect.

Option e. is given as, “none of the above is true”.

Fungal cells possess cell walls made up of chitin and it is absent in the animal cells. This makes option c. correct. Hence, option e. is incorrect.

Hence, the options a., b., d., and e. are incorrect.

Conclusion

Thus, cell walls mainly composed of chitin is present in fungal cells, but it is absent in the animal cells.

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.)   Data Table 1Stage    Totals    PercentInterphase        Mitosis:        Prophase        Metaphase        Anaphase        Telophase        Cytokinesis        Totals    100    100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
