Answer to Problem 1TYK
Correct answer:
The mycelial growth habit leads to a body with a high surface-area-to-volume ratio to have a large surface area for absorption.
Explanation of Solution
Explanation/justification for the correct answer:
Option (a) is given that the mycelial body has a high surface-area-to-volume ratio to have a large surface area for absorption. The fungi feed on the dead and the decaying organism. The long length of mycelia increases its surface area that helps them to easily absorb the food material (nutrients). Hence, Option (a) is correct.
Explanation for incorrect answer:
Option (b) is given that the mycelial body has a high surface-area-to-volume ratio, so that the hyphae that makeup mycelia are long, thin tubes. The large surface area of mycelia helps in absorption of nutrients. So, it is a wrong answer.
Option (c) is given that the mycelial body has a high surface-area-to-volume ratio, so that most hyphae are broken up into compartments by walls called septa, although some exist as single, gigantic cells. The distribution of mycelial body into fragments helps in asexual reproduction and has no relation to the large surface area of the mycelial body. So, it is a wrong answer.
Option (d) is given that mycelial body has a high surface-area-to-volume ratio so, that the hyphae can infiltrate living and dead tissues. The infiltration of living or dead tissue is done by the pores in the septa that separate the hyphae into compartments. So, it is a wrong answer.
Hence, options (b), (c), and (d) are incorrect.
The mycelial growth habit results in the development of high surface-area-to-volume ratio. The large surface area is important, so that the mycelia have increased area for the absorption of nutrients from the dead decaying food source.
