The answer is diatoms.
The organism is unicellular, but contains cell organelles, so it must be in the domain Eukaryota. It also has chloroplast, so it could be some plant or algae, but since it is unicellular it must be algae. Among the algae, diatoms are specific for their <span>glass-like cell walls with sculpturing.</span>

Explanation:
In the reflex arc, a signal is generated by the sensory cells and is conducted with the help of interneurons and returns back using motor neurons to bring out the reflex. The nerve pathway taken by a reflex action is known as a reflex arc. In the process, a receptor situated in the skin determines a stimulus. After that the sensory neuron transmits electrical impulses towards a relay neuron, and this relay neuron associates sensory neurons to the motor neurons. The motor neurons further transmits electrical impulses to an effector. The effector eventually generates a response.
Cholesterol makes up cell membranes and is used to create hormones.
Cell membranes are the outer covering of the cell that protect it from the outer environment. A cell membrane is a bilayer of lipid, composed of protein and cholesterol as well. The cholesterol is essential to maintain the proper integrity of the cell membrane.
Hormones are the chemical messengers that are released at one site and they perform their function at another location of the body. Hormones can be made up of several macromolecules like polypeptides, amine acids or cholesterol. The example of hormones made up of cholesterol are: glucocorticoids, mineralocorticoids, and sex hormones.
