The document discusses the key parts of a cell's nucleus. It describes the nucleus as the cell's CPU that stores DNA and coordinates cellular activities. Chromosomes within the nucleus contain the cell's genetic material. The nucleolus manufactures ribosomes for protein production. The nuclear envelope forms a double membrane around the nucleus, and nuclear pores regulate molecular passage between the nucleus and cytoplasm. In summary, the nucleus is the control center of the cell that stores DNA and directs cellular functions and reproduction.

3. Chromosome: Greatest Data
Long strands containing hereditary
materials, genes and DNA, where all
of the information about biological
characteristics of an organism is kept.

4. Nucleus: Cell’s CPU
a highly specialized organelle that
serves as the information processing
and administrative center of the cell.
Functions:
1. it stores the cell's DNA
2. coordinates the cell's activities,
which include growth,
intermediary metabolism, protein
synthesis, etc.

5. Nucleolus: Ribo-Factory
a membrane-less organelle
Through the microscope, the
within the looks like a large dark spot
nucleolus nucleus that
manufactures ribosomes, the may
within the nucleus. A nucleus
cell's protein-producing
contain up to four nucleoli, but within
structures. the number of nucleoli is
each species
fixed.

6. Nuclear Envelope: Fence
double-layered membrane that
encloses the contents of the
nucleus during most of the cell's
lifecycle. The space between the
layers is called the perinuclear
space and appears to connect with
the rough endoplasmic

7. Nuclear Pores: Gatekeeper
regulate the passage of molecules
between the nucleus and cytoplasm,
permitting some to pass through the
membrane, but not others. Building
blocks for building DNA and RNA are
allowed into the nucleus as well as
molecules that provide the energy for
constructing genetic material.

8. Summary
Cell is the basic building block of an
organism. All living things has a cell- it
is either uni or multicellular. Amazingly,
this cell was controlled by an intricate
system called nucleus; which controls
cellular synthesis, metabolism and
reproduction.
