GENERAL HISTOLOGY

Detailed explanation-1: -Eukaryotes (meaning ‘true nuclei” where “karyote” is derived from the ancient Greek for “kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.

Detailed explanation-2: -Eukaryotic cells contain a true nucleus where DNA is found. Examples of eukaryotes include all plants, animals, and fungi. The organisms in Domains Bacteria and Archaea are prokaryotic, meaning that their cells do not have a true nucleus, but rather have a nuclear region.

Detailed explanation-3: -Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Detailed explanation-4: -Final answer: They have a well-organized nucleus and they have a nuclear membrane statements are true for eukaryotic cells.

Detailed explanation-5: -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.
