In the beginning, there were Cells…
• Bacteria are thought to
be the earliest forms of
life on the planet.
• Simple life flourished in
tidal pools near the sea.
• Water was warm and
full of nutrients.
Bacteria evolved into
different cell types
• Some bacteria evolved
into protists.
• There are three types of
protists which later
evolved into more
complex organisms.
– Protozoa  animal-like
– Algae  plant-like
– Slime molds  fungi-like
Protozoa consume
other organisms for
energy like animals do
Algae make
sugar through
photosynthesis
like plants do
Slime molds
reproduce
using spores
like fungi do

Chloroplasts
• Membrane-bound organelle
found in all eukaryotic cells
• Chloroplasts are the food
producers of the cell.
• “Powerhouse” of the cell
• They are only found in plant
cells and some protists.
• Converts sugars into
useable energy for the cell
CELLULAR RESPIRATION
PHOTOSYNTHESIS
CELL WALL
• Found in plants, algae, fungi, and
most prokaryotes
• Porous to micromolecules and
dissolved materials
- water
- oxygen
- carbon dioxide
• Achaea: cell wall = proteins
• Bacteria: cell wall = proteins and
polysaccharides
• Plants: cell wall = polysaccharides
