DENDROLOGY

Detailed explanation-1: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-2: -These cells do not have membrane-bound cell organelles such as Golgi bodies, mitochondria, lysosomes, ER, peroxisomes, etc. Prokaryotes do not have a nucleus, so hence do not have a nucleolus.

Detailed explanation-3: -Interestingly, “prokaryote” means “before the nucleus, ‘’ and refers to a cell structure where the chromosomal DNA is not enveloped in any internal membrane but is free in the cell cytoplasm.
