2. A living cell is a complex, multi-functional unit.
Even the simplest of cells performs a large array
of different tasks and functions. Despite our size
prejudice, which makes us view cells as very tiny,
they are very large places at the level that
matters.

3. Types of Cells
1-Prokaryotic Cells
 Capsule - outer sticky protective layer
 Cell Wall - rigid structure which helps the bacterium
maintain its shape.
 Plasma membrane - separates the cell from the
environment
 Embosomed - enfolding of plasma membrane to aid in
compartmentalization
 Nucleoli - region where naked DNA is found
 Cytoplasm

4. 2-Eukaryotes:
 These are cells with a nucleus, this is where the genetic
material is surrounded by a membrane much like the
cells membrane. the genetic material forms multiple
chromosomes, that is linear and complexes with
proteins that help it 'pack' and is involved in
regulation.
