Why do prokaryotes not have cell specialization

Prokaryotes are defined by their lack of membrane bound organelles, so the reason prokaryotes don’t have them is that any cell that does have membrane-bound organelles would, by definition, not be called a prokaryote, because that is what humans have arbitrarily defined a prokaryote to be.

A more interesting question might be why cells with membrane-bound organelles evolved on earth, as far as we know, only once, among the eukaryotes, and why no other group among either the bacteria or the archaea, the two great prokaryotic groups who together make up over 2/3 of all life on earth, ever evolved membrane bound organelles.

That question takes us all the way back to the origin of eukaryotes themselves in an endosymbiotic merger between a bacteria and an archaean, and is a topic that would fill multiple books.

A very simplified answer is that, in order to support membrane-bound organelles a cell requires an active cytoskeleton and an internal membrane system, and supporting those two features requires a lot if energy, which eukaryotic cells produce using multiple mitochondria. Prokaryotic cells lack mitochondria and cannot produce energy at a fast enough rate to support such “expensive” adaptions.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
