The nucleus is the most conspicuous organelle found in a eukaryotic cell. It is surrounded by its own membrane, known as the nuclear membrane or nuclear envelope, and contains the cell's chromosomes and DNA. The nucleus is responsible for controlling the cell's activities, such as growth and metabolism, using the DNA's genetic information. The nucleolus, a smaller structure within the nucleus, is responsible for the synthesis of protein and RNA.

The nucleus is the most conspicuous organelle found in a eukaryotic cell
Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA's orders to the rest of the cell and serves as a template for protein synthesis. Nucleoli in the nucleus are responsible for the synthesis of protein and RNA.
The nucleus is spheroid in shape and separated from the cytoplasm by the nuclear envelope. It is often referred to as the cell's command centre due to its important role in controlling the cell's activities and functions.
The primary function of the nucleus is to monitor cellular activities, including metabolism and growth, by making use of the DNA's genetic information. This allows the nucleus to control the characters and functions of cells in the body, ensuring that they develop and function properly.

The nucleus controls the characters and functions of cells in the body
The nucleus is the organelle composed of DNA and protein. It is a large organelle that stores the cell's DNA and is surrounded by its own membrane, known as the nuclear membrane or nuclear envelope. The nucleus is the cell's "command centre", controlling all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
The nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes and is the site of almost all DNA replication and RNA synthesis. The nuclear envelope isolates and protects the cell's DNA from various molecules that could accidentally damage its structure or interfere with its processing.
Within the nucleus is a smaller structure called the nucleolus, which is responsible for the synthesis of protein and RNA. RNA helps convey the DNA's orders to the rest of the cell and serves as a template for protein synthesis.
Ribosomes are the protein factories of the cell. They are composed of RNA and protein and are responsible for processing the genetic instructions carried by mRNA. They can be found floating freely in the cell's cytoplasm or embedded within the endoplasmic reticulum.

Ribosomes are the protein factories of the cell. They are composed of two subunits and can be found floating freely in the cell's cytoplasm or embedded within the endoplasmic reticulum. They are composed of RNA and protein and are responsible for processing the genetic instructions carried by mRNA.
The nucleus is surrounded by its own membrane with tiny holes termed nuclear pores. This membrane is called the nuclear membrane or nuclear envelope. The nuclear envelope isolates and protects a cell's DNA from various molecules that could accidentally damage its structure or interfere with its processing.

The endoplasmic reticulum is a network of membranous canals filled with fluid
The nucleus is the organelle that contains DNA and proteins. It is the most conspicuous organelle found in a eukaryotic cell and houses the cell's chromosomes. The nucleus is surrounded by a membrane with tiny holes, known as the nuclear membrane or nuclear envelope. It is separated from the cytoplasm by this membrane, which isolates and protects the cell's DNA from accidental damage. The nucleus controls the cell's activities, such as growth and metabolism, using the DNA's genetic information.

The endoplasmic reticulum is a network of membranous canals filled with fluid. It is the transport system of the cell, involved in transporting materials throughout the cell. There are two different types of endoplasmic reticulum: rough endoplasmic reticulum and smooth endoplasmic reticulum. Rough endoplasmic reticulum is involved in protein manufacture and is composed of cisternae, tubules, and vesicles, which are found throughout the cell.
Ribosomes are found in both prokaryotes and eukaryotes. They are non-membrane-bound and important cytoplasmic organelles found in close association with the endoplasmic reticulum. They are found in the form of tiny particles in a large number of cells and are mainly composed of 2/3 RNA and 1/3 protein.
