The endosymbiotic theory states that primitive cells engulfed other primitive cells and in this way complex cells were formed. This theory suggests that the ability of cells to form organelles like the mitochondria and chloroplasts is due to the engulfment of primitive cells. The engulfed primitive cell then formed a symbiotic relationship with the host cell providing energy to the host cell while receiving protection and nutrition. This symbiotic relationship eventually led to the formation of cells with organelles which are known as eukaryotic cells.If the endosymbiotic theory is true cells would become more complex with the ability to store more energy and develop more advanced structures. This would enable them to perform more complex functions and become more efficient. For example cells with mitochondria and chloroplasts would be able to produce more energy-rich molecules such as ATP which would give them the ability to perform more tasks. Additionally the presence of membrane-bound organelles would allow for compartmentalization of the cell which would enable the cell to perform different functions simultaneously.In addition to the development of organelles the presence of a eukaryotic cell would also allow for the formation of specialized cell structures such as cilia and flagella. These structures would enable the cell to move further increasing its ability to survive and reproduce. Furthermore the presence of a nucleus would allow for the development of genetic material which would enable the cell to make copies of itself and pass on its genetic information to its offspring.
The structures that enable cells to live and reproduce are the organelles. The organelles of a cell are like the organs found inside the human body.

Cells look different because they have specialized structures and functions that are necessary for their specific roles in the body. Different types of cells have different shapes, sizes, and organelles that enable them to carry out their specific functions. For example, nerve cells have long extensions called axons that allow them to transmit electrical signals, while muscle cells have a unique contractile structure that enables them to generate force for movement.
