ADVERTISEMENTS: The following points highlight the eight important cytoplasmic inclusions found in bacteria.

It is formed by excretory product of bacteria. (adsbygoogle = window.adsbygoogle || []).push({}); Bacterial are unicellular prokaryotic organism. Attachment: pili helps the bacteria to attach the host cell surface. Gaurab Karki Become a Study.com member to unlock this It has very diverse roles in bacterial and eukaryotic cells, including phosphate reserves, cation sequestration and storage, cell envelope formation and function, modulating gene expression, regulation of enzyme activity, stress response and stationary phase adaptation, membrane channel function… Spore is metabolically dormant structure produced during unfavourable condition by the process called sporulation, Sporulation occur during late log phase or early stationary phase. Cell membrane is the inner layer that lies inside the cell wall and encloses the cytoplasm. 2018 May 17;84(11):e00399-18. A–C. 2016 Dec 5;2:16222. doi: 10.1038/nmicrobiol.2016.222. answer! Prosthecae increase surface area for nutrition absorption. Granule-associated enzymes (granzymes) are a family of serine proteases originally discovered in the cytotoxic granules of cytotoxic lymphocytes, which play a major role in the immune response against tumors, intracellular pathogens, and virus-infected cells [1–3]. Literally, all the cellular content including nucleus, and other cell organelle are floating in cytoplasm. NIH Some prosthecae develop bud at the tip and hence helps in reproduction. 2013;68:79-115. doi: 10.1007/978-94-007-6552-8_3.
