nucleus
The endoplasmic reticulum (ER) is a series of interconnected tubules present throughout the cell that is responsible for transporting and modifying proteins. Proteins are synthesized on the ribosomes attached to the rough ER, then transported through the ER network to undergo further processing before reaching their final destination in the cell.

microtubule
Through a series of tubes. You know, the internet.
cytoskeleton
The cytoskeleton is a network of hollow tubes made of proteins called microtubules that provide support and maintain the shape of the cell. They are involved in various cellular functions such as cell division, intracellular transport, and movement.

In plants that do not have tubes, like non-vascular plants, food and water are transported from cell to cell through a process known as simple diffusion. This movement occurs within the plant tissues and does not rely on specialized structures like xylem or phloem.
