What structure is formed by lysosomes?

Lysosomes are membrane-bound organelles that contain digestive enzymes. Their primary function is to break down waste materials and cellular debris, facilitating the recycling of organic materials for the cell. The Golgi apparatus is the correct answer because it plays a crucial role in the formation and transport of lysosomes. It processes, sorts, and packages proteins and lipids that are synthesized in the endoplasmic reticulum before they are sent to their final destinations, including the lysosomes.

The other structures mentioned do not relate directly to the formation of lysosomes. Mitochondria are involved in energy production, the nucleus houses genetic material and regulates gene expression, and ribosomes are responsible for protein synthesis. Thus, the Golgi apparatus is essential in the lifecycle of lysosomes, making it the right choice in this context.
