EVERYDAY SCIENCE

Detailed explanation-1: -Hint: The prokaryotes are the organism that lacks the cell nucleus and the eukaryotes are the organism that have cell nucleus present. Prokaryotes are either unicellular or multicellular.

Detailed explanation-2: -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-3: -Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm.

Detailed explanation-4: -Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.

Detailed explanation-5: -False. Eukaryotic cells have a nucleus and other membrane-bound organelles. In contrast, prokaryotic cells do not have a nucleus. Eukaryotic cells have a true nucleus that is surrounded by a membrane.
