Proteins synthesised in the RER pass through different regions of golgi apparatus (cis, median and trans golgi) where it undergoes further modification.įunction: GA is the sorting centre of the cell. Golgi apparatus ( GA): Consists of parallelly arranged flattened membranous sacs that lacks ribosomes. They also aid in destruction of invading bacteria just like lysosome in animal cellsĥ. įunction: Vacuoles play a major role in autophagy, maintaining a balance between biogenesis (production) and degradation of many substances and cell structures. Vacuoles : Often the largest organelle in a plant cell, bounded by a single membrane called tonoplast. Smooth Endoplasmic reticulum ( SER): interconnected network of membrane vesicles without ribosomes that’s why called “smooth”.įunction: lipid biosynthesis including cholesterol and phospholipid synthesis and drug detoxificationĤ. Secretory and membrane proteins and post translation modification (proteinģ. On the membrane of RER, ribosomes are attached to transmembrane glycoproteins Ribosomal subunits, 40S and 60S are synthesized Detailed notes on NucleolusĬonsists of interconnected network of membrane vesicles studded with ribosomes. Nucleolus: Nucleolus are membrane less prominent spherical colloidal bodies rich in What Is the Function and Structure of Mitochondria?
