The nucleus is an organelle that contains the genetic information for that organism. In an animal cell, the nucleus is located in the central region of the cell. In a plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the center of the cell.

The semifluid matrix found inside the nucleus is called nucleoplasm. Within the nucleoplasm, most of the nuclear material consists of chromatin, the less condensed form of the cell’s DNA that organizes to form chromosomes during mitosis or cell division.

As the organelle that contains the genetic material of a cell, the nucleus can be described as the command center. As such, the nucleus consists of a number of structured elements that allow it to perform its functions. The shape of a nucleus, however, may also change as the cell matures.

Answer:The nucleus is called the “director” of the cell because it controls the cell’s activities. The nucleus is the is organelle that directs all of the other functions of the cell. DNA, the genetic material of an organism, is located in the nucleus. DNA is made of amino acids, which combine to form proteins.

The study of the nucleus is called Karyology. Karyology is a branch of Cytology (Study of Cells) ,dealing with the structure of cell nuclei, especially chromosomes.

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.

The nucleus has 2 primary functions:

• It is responsible for storing the cell’s hereditary material or the DNA.
• It is responsible for coordinating many of the important cellular activities such as protein synthesis, cell division, growth and a host of other 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.

Types of Nucleus:

• Uninucleate cell: It is also referred to as monokaryotic cell, mostly plant cell which contain single nucleus.
• Bi-nucleate cell: It is also called as dikaryotic cell, which contains 2 nucleus at a time.
• Multinucleate cells:
• Enucleate cells:

The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.)

The mass of the nucleus is associated with the atomic mass number, which is the total number of protons and neutrons in the nucleus of an atom. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams. Besides the standard kilogram, it is a second mass standard.

Mostly the shape of the nucleus is spherical or oblong. Usually cells have one nucleus but many at times there are multinucleated cells.

Nuclei are smaller than most eukaryotic cells, but bigger than some prokaryotic cells. Chromosomes tend to be smaller than cells or nuclei, and genes are parts of chromosomes.

Ernest Rutherford’s

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

What is the nucleus?

• The nucleus is an organelle found in most eukaryotic cells, the exception being red blood cells.
• The primary functions of the nucleus are to store the cell’s DNA, maintain its integrity, and facilitate its transcription and replication.

1 : a usually round part of most cells that is enclosed in a double membrane, controls the activities of the cell, and contains the chromosomes. 2 : the central part of an atom that comprises nearly all of the atomic mass and that consists of protons and neutrons.

The nucleus is like the principal of a school, because the nucleus controls the cell like the principal controls the school. 2. Ribosome- The site where amino acids are hooked together to make proteins. Ribosome are like a factory, because ribosomes make proteins like factories make different products.

The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.

In 1911, Rutherford, Marsden and Geiger discovered the dense atomic nucleus by bombarding a thin gold sheet with the alpha particles emitted by radium. From this observation, they concluded that almost all the atomic matter was concentrated in a tiny volume situated at the atome center, the atomic nucleus.

An analogy for the nucleus is that the nucleus is like the boss of a factory.

The Nucleus(also known as the Brain) function is to help control eating, movement and reproduction. As of being the brain of the cell, it houses all genetic material (such as your DNA) and/or information. The nucleus is like Barack Obama(the President).
