I’m think it is liver cells because The rough ER helps modify proteins that will be secreted from the cell, cells whose job is to secrete large amounts of enzymes or other proteins, such as liver cells, have lots of rough ER.
That would be the mitochondria. They produce the energy needed for activities that occur in the cell, thus its being called the "powerhouse of the cell"
It is the main endocrine gland and a small structure in the head. It's named the "master gland" because it produces hormones that control other glands and many other body functions including growth. It consists of the anterior and posterior pituitary.
