Detailed explanation-1: -Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.

Detailed explanation-2: -The endoplasmic reticulum (ER) is a complex, extensive network that transports materials throughout the inside of a cell.

Detailed explanation-3: -Endoplasmic Reticulum The ER has two major functions: Transport: Molecules, such as proteins, can move from place to place inside the ER, much like on an intracellular highway. Synthesis: Ribosomes that are attached to ER, similar to unattached ribosomes, make proteins. Lipids are also produced in the ER.

Detailed explanation-4: -The endoplasmic reticulum transports materials within the cell. Mitochondria generate energy for the cell’s activities. Lysosomes contain enzymes that can break down particles entering the cell.

Detailed explanation-5: -The ER has been shown to be closely apposed to almost all membrane-bound organelles, including the PM, mitochondria, lipid droplets, Golgi, endosomes, and peroxisomes (Fig.
