Glycocalyx in prokaryotic cells
WebThe prokaryotic cells have four main components: Plasma Membrane- It is an outer protective covering of phospholipid molecules which separates the cell from the surrounding environment. Cytoplasm- It is a jelly-like … WebJun 8, 2024 · Key Points. Prokaryotes lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration. Prokaryotic cell size ranges from 0.1 to 5.0 μm in diameter.
