The largest amount of dna in a plant cell is contained in

The largest amount of dna in a plant cell is contained in a nucleus.

Explanation:

The nucleus is like the "brain" of the cell, because it is from it that "decisions" depart. This is where the chromosomes composed of deoxyribonucleic acid molecules, DNA, are located, which carry all the information about the characteristics of the species and participate in the hereditary mechanisms.

Each region of DNA is made up of genes that encode the information for protein synthesis that occurs in ribosomes. According to the encoded gene, a type of protein will be synthesized which will be used for specific purposes.

Moreover, when the organism needs to grow or reproduce the cell goes through divisions that also happen in the nucleus.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

yes it is weird but true
