Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
Typically, the genotype is encoded in the DNA by the gene; this gene in the DNA will then undergo the process of transcription and the information in the gene will be transcripted into mRNA. The mRNA will then undergo the process of translation and the information in the mRNA will be translated into a polypeptide chiefly by the action of ribosome. Thus, bacteria with different genotypes will have different protein which automatically means that they will have different phenotypes.
