NEET BIOLOGY

Detailed explanation-1: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-2: -Prokaryotes (meaning ‘before nucleus’) are cells without a definite nucleus. The DNA floats in the cytoplasm and they divide through mitosis. RBC and platelets present in eukaryotes also do not have the nucleus.

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: -Overview. There are two basic types of cells: prokaryotic cells, which lack a nucleus, and eukaryotic cells, which contain a nucleus. Prokaryotic cells are found in single-celled organisms, such as bacteria. Eukaryotic cells are found mainly in multicellular organisms.

Detailed explanation-5: -Prokaryotic cells have a true nucleus called nucleoid.
