Answer:
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.
