How do xylem and phloem contribute to the stem’s functions?

The vascular bundles are arranged in a ring near the edge of the stem, with the phloem on the outside and the outside and the xylem on the outside . This arrangement allows the stem to resist bending forces caused by the plant's weight and wind.

Explanation:

Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.

option D

Explanation:

The alleles of a gene can be described as the variant form of a gene. for example A and a are two alleles coding for the trait tallness. these forms are located at the same position ie locus on a chromosome. thus they are located on the same position for two similar chromosomes (homologous chromosomes).
