The nucleus is the main organelle in a cell. It controls all activities happening in the cell and also contains chromosomes, which helps in the reproduction of the cell. But eventually, there are some cells, in particular, the red blood cell, don't have a nucleus to contain more haemoglobin. Hence they live a shorter lives than a typical cell
Bacteria are prokaryotic organisms.They do not have a nucleus .
mRNA (messenger RNA) is the molecule that carries the genetic information encoded in the DNA in the nucleus to the ribosomes in the cytosol. It serves as a template for protein synthesis, with the sequence of nucleotides determining the order of amino acids in the polypeptide chain.
The nucleus in a plant cell is a membrane-bound organelle that houses the cell's genetic material and controls cellular activities such as growth, metabolism, and reproduction. It contains the cell's DNA organized into chromosomes and is responsible for regulating gene expression and protein synthesis. The nucleus also plays a key role in cell division and passing on genetic information to offspring.
Karyoplasm is a term used to refer to the cytoplasm contained within the nucleus of a cell. It consists of various proteins and nucleic acids that play a role in regulating gene expression and supporting nuclear processes.

The nucleus is in the center of the lens, the cortex surrounds the nucleus, and the capsule is the outer layer.
The main scientist was Robert Brown. He made a detailed description of the cell nucleus and he also gave nucleus it's name
