Answer:
The correct answer is Glomeromycota
Explanation:
Arbuscular mycorrhizae are characterized by the formation of unique structures, arbuscles, coils and vesicles of fungi of the phylum Glomeromycota. They are a type of endomicorrhiza in which the fungus penetrates the cortical cells of the roots of a vascular plant.
In this symbiotic association, the fungus helps the plant to capture nutrients such as phosphorus, sulfur, nitrogen and soil micronutrients. It is believed that the development of symbiosis with arbuscular mycorrhizae played a crucial role in the initial colonization of the earth by plants and in the evolution of vascular plants.
This symbiosis is a highly evolved mutualistic relationship found between fungi and plants.
Answer: The study of plant varieties.
Explanation:
This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.
Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.
He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.
