Write a short note on nucleus of a cell
Answers
Answer:
The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm, and the nuclear matrix (which includes the nuclear lamina), a network within the nucleus that adds mechanical support
This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
Answer:
Hey mate here is your answer..,
Explanation:
The nucleus is one of the most important cell organelles found in eukaryotic cells. It is a membrane-bound organelle that contains the entire genetic information of the cell.
Historically, the nucleus was one of the very first cell organelles to discovered and documented. The earliest recorded instances of the nucleus can be traced back to the drawings of Antonie van Leeuwenhoek, in the 18th century.
The nucleus is also one of the largest structures in the cell, occupying almost 10% of the cell’s total volume in most eukaryotic cells.
