Organelles are specialized membrane-enclosed structures in the cytoplasm of eukaryotic cells. The nucleus, which contains DNA in the form of chromosomes, is the most characteristic eukaryotic organelle.The nuclear envelope is connected to a system of membranes in the; cytoplasm called the endoplasmic reticulum (ER).he nucleus, which contains DNA in the form of chromosomes, is the most characteristic eukaryotic organelle.

Eukaryotic cells: 1  More complex. 2  DNA is located in the nucleus, bonded by a double membrane. 3  Contain true nuclei in which chromosomes are compacted as chromatin. 4  Contain membrane-bound organelles. 5  Have linear DNA and contain histone proteins. 6  Larger - typically 10-100 micrometers in diameter. 7  Have a complex cytosketeton.
