NEET BIOLOGY

Detailed explanation-1: -Most prokaryotes are small, single-celled organisms that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm.

Detailed explanation-2: -They are organisms which do not have proper cellular organization i.e they lack cellular organelles and a nucleus and therefore are small in size.

Detailed explanation-3: -Prokaryotic cells tend to be small, simple cells, measuring around 0.1-5 m in diameter. While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions. In prokaryotic cells, DNA bundles together in a region called the nucleoid.

Detailed explanation-4: -Cell size. Typical prokaryotic cells range from 0.1 to 5.0 micrometers (m) in diameter and are significantly smaller than eukaryotic cells, which usually have diameters ranging from 10 to 100 m.

Detailed explanation-5: -Prokaryotes include bacteria and archaea, two of the three domains of life. Prokaryotic cells were the first form of life on Earth, characterized by having vital biological processes including cell signaling. They are simpler and smaller than eukaryotic cells, and lack a nucleus, and other membrane-bound organelles.
