Explanation:
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. It’s RBC (Red Blood Corpuscles) and platelets.
