gtnhenbr [62]

O relatively large genome, dynamic cytoskeleton, compartmentalized metabolic processes

Explanation:

Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue. 

DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome.

Eukaryotic cells generally use aerobic respiration – requiring oxygen – to produce usable energy called ATP from glucose molecules. ... Prokaryotic cells, on the other hand, tend to use anaerobic respiration – not requiring oxygen.
