NCERT CLASS-XI : Page No. 133, 134.

 The endomembrane system include endoplasmic reticulum (ER), golgi complex, lysosomes and vacuoles.

RER is frequently observed in the cells actively involved in protein synthesis and secretion.

The smooth endoplasmic reticulum is the major site for synthesis of lipid.

The isolated lysosomal vesicles have been found to be very rich in almost all types of hydrolytic enzymes (hydrolases – lipases, proteases, carbohydrases) optimally active at the acidic pH. 

The vacuole is the membrane-bound space found in the cytoplasm. It contains water, sap, excretory product and other materials not useful for the cell. The vacuole is bound by a single membrane called tonoplast. In plant cells the vacuoles can occupy up to 90 percent of the volume of the cell.Anthocyanins are water soluble pigments found in vacuoles.
