Question

what is nucleus . in 60/70 words

Answer 1

Answer:

The nucleus is an organelle found in most eukaryotic cells, the exception being red blood cells. In animal cells it is both the largest and stiffest organelle and is easily identifiable by light microscopy. The average mammalian nucleus has a diameter of ~6µm and occupies about 10% of the total cell volume.

Answer 2

The nucleus is a pivotal organelle responsible to regulate almost all forms of cellular activities. Mostly, every type of cell that exists is categorized on the basis of the absence or presence of the nucleus within its cell (categorized either as a prokaryotic or eukaryotic cell.)

Structure Of Nucleus

• Typically, it is the most evident organelle in the cell.
• The nucleus is completely bound by membranes.

• It is engirdled by a structure referred to as the nuclear envelope.

• The membrane distinguishes the cytoplasm from the contents of the nucleus

• The cell’s chromosomes are also confined within it.
