Nuclear parts of a cell o Nucleus: contains chromosomes, & regulates DNA of the cell. Defining structure of eukaryotic cells (they all have nucleus). Passes genetic traits between generations. Contains nuclear envelop, nucleoplasm, nucleolus, nuclear pores, chromatin, & ribosomes. o Chromosomes: thread like rods of DNA. Short deoxyribonucleic acid, DNA is the genetic material that stores information about the plant/animal. o Chromatin: DNA & Protein makeup chromosomes o Nucleolus: Proteins,...
