I'm Gary Buckholz, Palliative Medicine Fellowship Director at The Institute for Palliative Medicine at San Diego Hospice. One of the most important things I can do is to decrease the symptom burden for patients who are suffering, and one of the most common symptoms I treat is shortness of breath, or dyspnea.
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 are large, advanced and multicellular. They do contain membrane-bound organelles (plants contain a large vacuole and chloroplasts) and do have a distinct nucleus (the nucleus is surrounded by a nuclear membrane and the DNA is therefore cut off from the cytoplasm).hey do not contain any membrane-bound organelles (such as chloroplasts, mitochondria, endoplasmic reticulum, etc) and do not have a distinct nucleus (ie: no nuclear membrane-so the DNA is floating around in the cytoplasm).
