Answer:

38

Explanation:

  • Sexual reproduction happens when there is the involvement of two parents to give rise to the offsprings.
  • For the production of offsprings, each of the parents produces a haploid gamete and it is by the fusion of these two haploid gametes that a diploid organism is produced.
  • In the given situation, there are 19 chromosomes present in the haploid gametes this means that a diploid individual will have 2X19 = 38 chromosomes.
  • Now the underground stem cells are not gametes but somatic cells and the somatic cells are diploid and hence, they will have 38 chromosomes.

Members of which phylum establish a successful symbiotic relationship with the roots of trees?
Alchen [17]

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.
