Detailed explanation-1: -Of all eukaryotic organelles, the nucleus is perhaps the most critical. In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell’s DNA is housed and the process of interpreting it begins.
Detailed explanation-2: -In eukaryotic cells, DNA is located only in the nucleus.
Detailed explanation-3: -The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material. The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus.
Detailed explanation-4: -Membrane-bound cell organelles include nucleus, vacuole, endoplasmic reticulum, chloroplasts, mitochondria, lysosomes, Golgi apparatus and are present only in eukaryotes.
Detailed explanation-5: -RBC and platelets present in eukaryotes also do not have the nucleus. It’s RBC (Red Blood Corpuscles) and platelets.
