Detailed explanation-1: -Plant and animal cells are eukaryotic, meaning that they have nuclei. Eukaryotic cells are found in plants, animals, fungi, and protists. They generally have a nucleus-an organelle surrounded by a membrane called the nuclear envelope-where DNA is stored.

Detailed explanation-2: -The nucleus is the membrane bound organelle in eukaryotic cells that stores DNA.

Detailed explanation-3: -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-4: -Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. The nucleus of eukaryotic cells is similar to the brain of the cell. It contains the genetic information (DNA) and directs the cell how to function.

Detailed explanation-5: -RBC and platelets present in eukaryotes also do not have the nucleus. It’s RBC (Red Blood Corpuscles) and platelets.
