The xylem is the structure of the plant that is
responsible for transporting water from the ground up to the different parts of
the plant. It is composed water, inorganic ions, and a number of organic chemicals.
<span>
Xylem tissue is found throughout the plant
because not only does it transport water, but it also transports the nutrients
that the plant needs for different processes. Aside from being responsible for
the transportation of materials, the xylem is also used to replace water that
was lost during photosynthesis and transpiration. </span>

It represents the genotype.
For example, Pp is heterozygous genotype, pp is recessive homozygous genotype, PP is dominant homozygous genotype. <span>But, combination and dominance between alleles can show different phenotypes. For example, complete dominance is when phenotype of the dominant allele is expressed in heterozygous. Codominance is when both alleles are expressed equally in heterozygous (phenotype is a combination of both).</span>
