2. Prokaryotes vs. Eukaryotes
• Prokaryotes are
organisms that do not
have a nucleus in their
cells. We call these cells
prokaryotic. They tend
to be smaller and are
usually in unicellular
organisms.
• Examples: bacteria
• Eukaryotes are
organisms that do have
a nucleus in their cells.
We call these cells
eukaryotic. They tend to
be larger and are
usually in multicellular
organisms.
• Examples: plants,
animals, protists
3. Unicellular vs. Multicellular
Unicellular means it is made of
only one cell.
That one cell of a unicellular
organism helps it survive, get
energy, reproduce and
respond to its surroundings.
Generally they are prokaryotic.
Examples: most protists, some
fungi, all archeabacteria and
all eubacteria
• Multicellular means it is
made of more than one cell.
Multicellular organisms
have specialized cells to do
certain jobs. For example,
blood cells carry oxygen,
immune cells fight
disease,…. Generally they
are eukaryotic.
• Examples: plants, animals,
some fungi, a few types of
protists
