What stores and delivers nutrients throughout the cell and transports waste to the cell membrane?

The endoplasmic reticulum (ER) is the organelle responsible for storing and delivering nutrients throughout the cell. It plays a crucial role in the synthesis, folding, modification, and transport of proteins and lipids. The rough endoplasmic reticulum (RER), which is studded with ribosomes, primarily assists in the production of proteins, while the smooth endoplasmic reticulum (SER) is involved in lipid synthesis and the metabolism of carbohydrates.

Additionally, the Golgi apparatus functions closely with the ER, modifying, sorting, and packaging proteins and lipids received from the ER for delivery to various parts of the cell or outside the cell.

For waste transport, lysosomes are important organelles that contain enzymes to break down waste materials and cellular debris, transporting waste to the cell membrane for disposal. Together, these organelles play vital roles in maintaining cellular health and homeostasis.
