=> Necleous :- The cell nucleus is the command center of our cells. It contains our chromosomes and genetic information needed for the reproduction of life.
The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
=> Cell Necleous Organelle:-
1. Necleous Pore :-
The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, thenucleus is separated from the cytoplasm and surrounded by anuclear envelope.
2. Necleous membrane :-
a double membrane enclosing a cell nucleus and having its outer part continuous with the endoplasmic reticulum — called also nuclear envelope; see cell illustration.
3. :Nucleoplasm-
Similar to the cytoplasm of a cell, the nucleus contains nucleoplasm, karyoplasm, or nucleus sap. The nucleoplasm is one of the types of protoplasm, and it is enveloped by the nuclear membrane (also known as the nuclear envelope). The nucleoplasm includes the chromosomes and nucleolus.
4.Nucleolus
The nucleolus (plural nucleoli) is a dense, spherical-shaped structure present inside the nucleus. Some of the eukaryotic organisms have nucleus that contains up to four nucleoli. The nucleolus plays an indirect role in protein synthesis by producing ribosomes. These ribosomes are cell organelles made up of RNA and proteins; they are transported to the cytoplasm, which are then attached to the endoplasmic reticulum.
=> Function of Necleous:-
<>. The nucleus is an organelle found in eukaryotic cells.
<>. Nucleus a double-membrane bound cell organelle present in eukaryotic cells. The nucleus constitutes most of the genetic material of the cell - the DNA.
<> Storage of proteins and RNA (ribonucleic acid) in the nucleolus.
<> Nucleus is a site for transcription in which messenger RNA (mRNA) are produced for protein synthesis.
<> Selective transportation of regulatory factors and energy molecules through nuclear pores.
=> choromosomes:-
They are made of protein and one molecule of DNA, which contains an organism's genetic instructions, passed down from parents. In humans, animals, and plants, most chromosomes are arranged in pairs within the nucleus of a cell. Humans have 22 of these chromosome pairs, called autosomes.
The substance consisting of all the chromosomes in a cell and all their associated proteins is known as chromatin. In prokaryotes, there is usually only a single chromosome, which exists in a ring-like or linear shape. The chromatin of most eukaryotic organisms consists of multiple chromosomes, as described later in the article.
=>Function of chromosome:-
<> Chromosomes are thread-like structures located inside the nucleus of animal and plant cells.
<> The chromosome holds not only the genetic code, but many of the proteins responsible for helping express it.
