Endoplasmic reticulum is the network of delicate strands and vesicles which extends from cell membrane to nuclear membrane. It acts as a circulatory system of cell and is of two typesrough endoplasmic reticulum and smooth endoplasmic reticulum. Rough endoplasmic reticulum involves in protein synthesis along with attached ribosomes and smooth endoplasmic reticulum helps in lipid and steroid synthesis. Cell wall is the outermost covering of plant cell generally made up of cellulose. Golgi bodies are double membrane bound cell organelles of eukaryotic cells which consist of vesicle, tubule and cisternae. Mitochondria is a rod-shaped, double membrane bound cell organelles.
