Answer to Problem 1MC
Correct answer:
Fungi have cell walls primarily composed of chitin.
Explanation of Solution
Explanation for the correct answer:
Option (c) is given that Fungi have cell walls primarily composed of chitin. Chitin is a strong substance. It is primarily found in exoskeletons of some insects and species related to crab for protection. This substance is also found in cell walls of fungi. This substance makes the tiny hyphae stronger and maintains their cell stability. Hence, option (c) is correct.
Explanation for incorrect answers:
Option (a) is given that Fungi have cell walls primarily composed of lignin. Lignin is a substance found primarily in the wood. This is a strong substance that makes the tree trunks hard. On the contrary, only some species of the fungi can decompose the lignin from the dead plant bodies. So, it is an incorrect option.
Option (b) is given that Fungi have cell walls primarily composed of cellulose. Cellulose is found in most of the plant cells. Most of the animals that eat plant cannot digest cellulose. So they let some species of fungi like rumen live in their gut symbiotically. These fungi digest cellulose. So, it is an incorrect option.
Option (d) is given that Fungi have cell walls primarily composed of glucose. Glucose molecules are the primary source of energy for fungi. They obtain it from other organisms by symbiosis or
Hence, options, (a), (b), and (d) are incorrect.
Therefore, cell walls of Fungi are primarily composed of chitin.

Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together.
