What structure is created when particles are entering the cell by endocytosis

Endosomes

Explanation:

In the endocytosis process, the formation of vesicles occurs by invagination of the plasma membrane for the absorption of organic molecules and other particulate substances. These vesicles are called endosomes.

The endosomes formed by the membrane containing the absorbed molecule break off and carry the molecule into the intracellular environment.

An example of endocytosis in the human body is the absorption of cholesterol for the synthesis of membrane and other steroids.
