Answer:

Nucleus - Structure and Functions of Nucleus

Introduction:

Cell:

The cell is the basic and structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life. Cells are called the building blocks of life. The study of cells is called cell biology.

The human body consists of trillions of cells, all with their own particular function. Cells are the fundamental or key structure of all living organisms. The Cell provides structure for the body, take in nutrients from food and carry out important functions.

There are two types of cell; one is prokaryotic (bacteria) and other eukaryotic (plant, animal, fungi). The prokaryotes have no nucleolus- the DNA is in the cytoplasm, it can form small circular strands of DNA called plasmids. Likewise, Eukaryotic cells all have their DNA enclosed in the nucleus.

The cell is made up of two-thirds water, which means that two-thirds of the whole body is water. The rest is a mixture of molecules, mainly lipids, proteins, and carbohydrates. The cells turn the raw materials in the food that we eat into the molecules the body needs, using thousands of different chemical reactions.

The nucleus is an organelle that consists of the genetic information for that organism. In an animal cell, the nucleus is located in the central place of the cell. Likewise, in the plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the centre of the cell.

Nucleus:

The nucleus is a spherical-shaped organelle that is present in every eukaryotic cell. The Nucleus is the control centre of eukaryotic cells. It is also responsible for the coordination of genes and gene expression. The structure of the nucleus includes nuclear membrane, chromosomes, nucleoplasm, and nucleolus.

The nucleus is the most prominent organelle as compared to other cell organelles, which account for about 10 percent of the volume of the cell. In general, a eukaryotic cell has the only nucleus. However, some eukaryotic cells enucleate cells (without a nucleus) for example red blood cells. Some are multinucleate; it means it consists of two or more nuclei, for example, slime mould.

The Nucleus is detached from the rest of the cell or the cytoplasm by a nuclear membrane.
