The brain.
Parenchyma is the bulk of an organ. Cells have nuclei. Organs comprise tissues, which comprise cells, each of which has a nucleus (RBCs excepted.)
The heart is the organ that acts like a pumping machine in the body. It circulates oxygen-rich blood throughout the body to deliver nutrients and oxygen to cells while removing waste products.

Some cells like seive tube elements lack.Other cells have a nucleus.
The nucleus is the control center of a cell, containing genetic material (DNA) that regulates cell activities. In the human body, the nucleus plays a key role in controlling processes such as cell growth, metabolism, and reproduction. It is essential for proper functioning and maintaining the integrity of cells in the body.
The brain.
Basically cells do not control rather they are part of the tissues and the tissues are part of the organ. The Cells are what makes the body part or the whole body what it is. They generate energy and they make up the whole body. The control center of the body is the brain which is made up of tissues and therefore made up of cells too.
The nucleus controls the cell. It is like the brain of the cell. Another way to put it is that the nucleus is like the control panel of the cells in your entire body. If that^ doesn't make sense then think of the nucleus as your brain. The cell is like your body. The brain( nucleus) controls your body's movements and reactions to certain things that do not include love.

No, weasels do not have a main nucleus, but their cells do.The weasel is an animal, therefore, it is a multicellular organism. All multi cellular organisms are composed of eukaryotic cells (as opposed to prokaryotic cells). Each eukaryotic cell contains its own nucleus. So the weasel itself does not have a nucleus, but its cells do. The equivalent to a nucleus in an animal's organ systems would probably be the brain. Both the nucleus and the brain are like the "command center."
Tissue.
your skin is technically and organ (called epidermis) and it is made of cells. sometimes the cells die, like and organ and shed then replace themselves. im sure about this, but i think your hair is the only dead part of your body.

it is in both, the nucleus is like the brain of the cell.
