Question

VAM stands for
A. Vesicular arbuscular mycorrhizae
B. Vesicle arbuscular mycorrhizae
C. Vermicular arbuscular mycorrhizae
D. Vacuolar arbuscular mycorrhizae

Answer 1

Hint: VAM is a symbiotic connection between angiosperm roots and some ascomycetous fungus. The plant benefits from this interaction because it receives phosphorus from the earth. The majority of plants in the vascular family have this type of interaction. The arbuscules are a unique structure formed by them. This mycorrhiza aids the plant in absorbing nutrients from the soil such as phosphorus, nitrogen, and sulphur.
VAM gives the plant the ability to fight disease microorganisms and withstand adverse weather conditions.

Complete answer:
Option A: Vesicular Arbuscular Mycorrhizae is an acronym for Vesicular Arbuscular Mycorrhizae. It is created by fungi and angiosperm roots forming a symbiotic relationship. The vesicular fungus penetrates the roots of vascular plants to aid in the capture of nutrients from the soil.
So, option A is correct.
Option B: The symbiotic relationship between certain ascomycetous fungi and angiosperm roots forms vesicular-arbuscular mycorrhiza (VAM).
So, option B is not correct.
Option C: VAM stands for vesicular arbuscular mycorrhizae.
So, option C is not correct.
Option D: Vesicular Arbuscular Mycorrhizae (VAM) is an abbreviation that stands for Vesicular Arbuscular Mycorrhizae. Fungi and angiosperm roots form a symbiotic interaction to produce it. The vesicular fungus infiltrates vascular plant roots to aid in the collection of nutrients from the soil.
So, option D is not correct.

So, option A is the correct answer.

Note:
A mutual link between two species is known as a symbiotic relationship. Both creatures gain from such a partnership in terms of shelter and nourishment. The mycorrhiza in VAM delivers nutrients to the plant. In exchange, the fungi are protected by the plant's roots. Rhizobium bacteria found in the root nodules of leguminous plants are another example of such a relationship.
