Grana is the site of light dependent reaction whereas stroma is the site of Chloroplast: semi-autonomous , double membrane bound organelle with DNA.

Detailed notes on ribosomesĬellular respiration therefore, called as “power house of the cell”, beta Both free ribosomes in cytoplasmĪnd attached ribosomes in RER are present.įunction: Protein synthesis. In plant cells, GA is involved in the deposition of primary and secondary wall materials (pectin, cellulose etc).Ĩ0S: are made up of several rRNA molecules and ribosomal 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?
