Introduction to cell

The document discusses the structure and function of prokaryotic cells. Prokaryotic cells are much smaller and simpler than eukaryotic cells, lacking organelles like the nucleus and mitochondria. The basic structure of a prokaryotic cell includes an outer cell wall and cytoplasmic membrane, cytoplasm containing ribosomes and other inclusions, and sometimes additional structures like flagella, pili, or plasmids. The cell wall provides shape and rigidity while the membrane is semipermeable and controls movement of molecules in and out. Ribosomes perform protein synthesis and mesosomes are involved in respiration.Read less
