Option A: Peptidoglycan: Bacterial and certain archaeal cell walls contain this kind of polymer. composed of repeated units of N-acetylmuramic acid and N-acetylglucosamine joined by peptide bonds. Option B: Chitin: This polymer is composed of repeated N-acetylglucosamine units joined by beta-1,4 glycosidic linkages. gives the cell wall its stiffness and strength. Option C: Suberin: A kind of waxy material present in plant cell walls. Option D: Cutin: The outermost layer of plant cell walls contains this kind of fatty material. Option E: All cell walls include proteins, which have a number of functions, including giving the wall structure, attaching it to other structures, and interacting with

The ergot fungus Claviceps purpurea develops on the ears of rye and other similar forage and cereal plants. Ergotism in humans and other mammals can result by eating grains or seeds tainted with the fungus’s survival structure, the ergot sclerotium.

Fungal cells lack chloroplasts and chlorophyll, in contrast to plant cells. Numerous fungi have vivid hues that range from red to green to black and are caused by various cellular pigments.

Glomerella tucumanensis is the fungus that causes red rot illness. It creates what are known as acervuli. This causes sporulation to be abundant. The fungus Phytophthora infestans is the cause of late blight in potatoes. It infects and kills tomato and potato plants’ leaves, stems, fruits, and tubers. Xanthomonas campestris is the bacteria that causes crucifer black rot. Fruit and vegetable leaves become discolored to a dark brown hue as a result. The fungus Puccinia triticina is the cause of wheat leaf rust. It affects the stems, leaves, and grains of wheat, barley, and rye. Therefore, “Black rot of crucifers” is the right response.

Since prions are infectious proteins that infect both people and cows, Option A is wrong. Option B is erroneous since algae don’t contribute to decomposition. Option C is accurate as only bacteria can match the ecological function of fungus as decomposers.
Since viruses don’t play a part in breakdown, Option D is wrong.

A few families of crustaceans, such terrestrial crabs and terrestrial hermit crabs, have evolved to living on land, but the bulk of them are aquatic and inhabit freshwater or marine settings. Each of the three cell layers that develop in the early embryo—the ectoderm, mesoderm, and endoderm—are referred to as germ layers. This is the right response since they have a cuticle covering.

Pyrophilus, or fire-loving, fungi are those whose growth is stimulated by fire. The fungi Prephylus, Prophylus, and Philus do not exist.

Notochords are only found in members of the phylum Chordata. Nematoda is the phylum in which roundworms belong.

A medication that specifically eradicates fungal infections is known as an antifungal agent. Penicillium griseofulvin produces the antifungal antibiotic griseofulvin.
