PATHOLOGY

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: -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-3: -Eukaryotic cells are cells that have a nucleus and membrane bound organelles. These cells make up the bodies of all multicellular organisms, such as plants and animals. However, eukaryotic organisms can also be unicellular, such as yeast and protists. There are also other types of organisms that are prokaryotic.

Detailed explanation-4: -The primary difference between prokaryotic and eukaryotic cells is that a nucleus and other membrane-bound organelles are only present in eukaryotic cells. Prokaryotic and eukaryotic cells make up prokaryotes and eukaryotes, respectively.
