Give the structural and functional aspects of the control centre of the cell
Answers
Answer:
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.
