Cell membrane, nucleus and cytoplasm

1. Main parts of a Cell
Organelles I

2. Prokaryotic vs. Eukaryotic

3. What do all Eukaryotic cells have in
common?
• Nucleus
• Cytoplasm
• Cell membrane

4. Cytoplasm
• Inner content of the cell mainly made of water and
where different structures, called organelles, are
found.

5. Organelles: Nucleus
• Nuclear envelope: made of a double
membrane which has pores that
allow the exchange of substances
• DNA: genetic material which has
the information that controls how
the cell functions (uncoiled 
Chromatin) (Condensed or coiled 
Chromosomes
• Nucleolus: where ribosomes are
synthesized

6. Activity
How many cells
do you see in
the image?

7. Cell membrane
• It is a thin layer that covers the cell and serves as a
boundary between the cell and the surrounding.
• Made up of a double layer of phospholipids.
• Contains protein molecules on the interior, the
exterior or across the lipid bilayer.
• Some are glycoproteins with carbohydrate chains

8. Phospholipid
MACROMOLECULE
Hydrophilic, polar head (contains
phosphate)
Hydrophobic, apolar, tail made up of 2
chains of fatty acids.
