Exploring Cell Organelles and Their Functions

The video tutorial explains the transportation of nutrients, wastes, and cell products within the cell, focusing on the endoplasmic reticulum (ER). It distinguishes between rough and smooth ER, highlighting their roles in protein synthesis and storage. Ribosomes, as the primary site of protein synthesis, are discussed, along with their location and function. The Golgi apparatus is described as a key organelle for sorting and processing proteins and lipids. Lysosomes are introduced as vesicles containing enzymes for digestion and recycling. Finally, mitochondria are presented as the cell's powerhouse, generating energy in the form of ATP.

What is the primary function of the endoplasmic reticulum (ER) in a cell?
