1. Explain the structure and function of the controlling centre of a cell
with a neat labelled diagram.
Answers
Answer:
here is the diagram ...and
explanation..
Nucleus is considered as the director or controller of the cell. The various structural components of nucleus are:
Nuclear membrane: Nucleus is a double membrane-bound organelle. The nuclear envelope consists of two membranes; an outer membrane and an inner membrane that are separated by perinuclear space. The nuclear membrane is perforated by apertures which are called nuclear pores.
Nucleoplasm: It is interior fluid just like the cytoplasm, which is enclosed by the nuclear membrane.
Nucleolus: The spherical body within the nucleus is placed centrally or peripherally in close association with the nucleolar organizer region of chromosomes. It is the site of RNA synthesis.
Chromatin: The organization of DNA and proteins inside the nucleus. When the cell prepares to divide, the chromatin condenses and becomes thick to form specialized structures called chromosomes.
Answer:
Centre of a cell is known as nucleus .

So according to ur question :-
Explain the function of the nucleus
------------------------------------------------
ANSWER
Following are the important nucleus function :-
▪️It contains the cells hereditary information and control the cells growth and reproduction .The nucleus has been clearly explained as a member bond structure that comprises the genetic material of a cell .
--------------------------------------------------
And for ur another question ( draw a clean Diagram ) . ------ U can see it in attachment .
------------------------------------------------
And ur another question :- Explain the structure of nucleus .
----------------------------------------------
The main structure making up the nucleus are the nuclear envelope , a double membrane that encloses the entire organelle and isolates it's contents from the cellular cytoplasm and nuclear matrix , a network within the nucleus that adds mechanical support .
