Hi mate

Question:

a) Explain the various structural components of nucleous.

Answer:

The five main components of the nucleus are,

  • Nucleolemma or nuclear membrane or karyotheca- is a limiting membrane that separates the nucleus from the cytoplasm and transports important material between the nucleus and cytoplasm.

  • Nucleolus is a spherical dark structure present inside the nucleus

  • Chromatin is genetic material made of DNA and histone protein

  • Nuclear matrix or nucleoplasm is semifluid homogenous substance.

Question:

b) Why is nucleus called the control centre of the cell?

The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins.
