THE NUCLEUS
Thia is the largest organelle of the cell often located in the central part of the cytoplasm and
enclosed in a nuclear membrane. Its shape usually corresponds to the shape of the cell in
which it is found. It contains a nucleolus/ nucleoli(which produces ribosomal subunits) and
chromatin (DNA). The nucleus is the control center of the cell contains the blueprint for all
cellular structure and activities and in its absence the cell can neither function nor survive.
the nuclear envelope is perforated by pores (3000-4000), which facilitate communication
between the nucleus and the cytoplasm. Attached to the outer membrane of the nuclear
envelope are polyribosomes, this membrane is also continuous with the rough endoplasmic
reticulum of the cytoplasm.
