Eukaryotic cell parts (know name, function, location)

Nuclear matrix

In biology, the nuclear matrix is the network of fibres found throughout the inside of a cell nucleus and is somewhat analogous to the cell cytoskeleton

Chromatin and chromosome differences

In the nucleus, the DNA double helix is packaged by special proteins (histones) to form a complex called chromatin. The chromatin undergoes further condensation to form the chromosome.

Nucleoplasm

Note: "nucleo" means nucleus so this will only be found in Eukaryotic cells because only Eukaryotic cells have a nucleus. Just like the cytoplasm found inside a cell, the nucleus contains nucleoplasm, also known as karyoplasm. The nucleoplasm is a type of protoplasm that is made up mostly of water, a mixture of various molecules, and dissolved ions. It is completely enclosed within the nuclear membrane or nuclear envelope

Nucleoplasm Function

Nucleoplasm Function: Nucleoplasm which is also referred to as karyoplasm or nuclear sap is fluid normally established in the nucleus of cells called eukaryotic. This fluid consists of mainly water, complex mixture of molecules, as well as dissolved ions. Its main function is to serve as a medium of suspension for the organelles of the nucleus. Additional functions include maintaining nuclear structure and shape as well as the transport of ions, molecules and additional substances that are vital to cell metabolism and functioning

chromosome function

the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent. In most organisms, one chromosome is inherited from the mother and the other is inherited from the father; to ensure that offspring carry traits from both parents.

chromatin function

to package DNA (deoxyribonucleic acid) into smaller volume that fit in the cell; to control gene expression as well as DNA replication; and to strengthen the DNA to promote mitosis and meiosis while preventing DNA damage.

Nuclear envelope

The nuclear envelope surrounds the nucleus with a double membrane with multiple pores. The pores regulate the passage of macromolecules like proteins and RNA, but permit free passage of water, ions, ATP and other small molecules

Nucleolus

The nucleolus, whose primary function is to assemble ribosomes, is the largest structure in the cell nucleus. The nucleolus organiser regions of chromosomes, which harbour the genes for pre‐rRNA, are the foundation for the nucleolus The nucleolus takes up around 25% of the volume of the nucleus. This structure is made up of proteins and ribonucleic acids (RNA). Its main function is to rewrite ribosomal RNA (rRNA) and combine it with proteins. This results in the formation of incomplete ribosomes

ribosomes

A cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; consists of rRNA and protein molecules, which make up two subunits.

chromosomes

A compact structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. chromosomes are made out of chromatid they are
