briefly explain the structure and function of nucleus
Answers
Answer:
The nucleus is an organelle that consists of the genetic information for that organism. ... The Nucleus is the control centre of eukaryotic cells. It is also responsible for the coordination of genes and gene expression. The structure of the nucleus includes nuclear membrane, chromosomes, nucleoplasm, and nucleolus.
The most integral component of the cell is the nucleus (plural: nuclei). It is derived from a Latin word which means “kernel of a nut”.
The nucleus is an important organelle responsible for controlling nearly all forms of cellular activities. Almost every kind of cell in existence is classified based on the presence or absence of the nucleus within its cell (classified either as a eukaryotic or prokaryotic cell.)
It is generally the most prominent organelle in the cell.
The nucleus is completely bound by membranes.
It is surrounded by a structure called the nuclear envelope.
This membrane separates the contents of the nucleus from the cytoplasm.
The cell’s chromosomes are also enclosed within it.
DNA is present in the Chromosomes and they provide the genetic information required for the creation of other cell components and also for reproduction of life.
- A structure called the nuclear envelope/ nuclear membrane surrounds the nucleus. It is a double-membraned organelle.
- Within the nucleus lies the nucleolus, which takes up 25% per cent of the volume.
- Also found within the nucleus are dense, thread-like structures called chromatins that contain DNA and proteins.
- The mechanical strength for the nucleus is provided by the nuclear matrix, a network of fibres and filaments which performs functions similar to the cytoskeleton.
Answer:
Nucleus is the largest cell organelle in the protoplasm . It controls all the activities of the cell . It controls cell divison. It is only found in eukaryotic cells . It is bounded by double membrane
