Key Terms to KnowKey Terms to Know• UnicellularUnicellular – made up of – made up of one cell one cell (ex. bacteria) (ex. bacteria)• MulticellularMulticellular – made up of – made up of more than one cell more than one cell (ex. you)(ex. you)• ProkaryoteProkaryote – cells with an outside membrane only, the – cells with an outside membrane only, the
organelles inside do not have membranes, organelles inside do not have membranes, no nucleusno nucleus• EukaryoteEukaryote – – cells with cells with outside membranes and the outside membranes and the organelles organelles
inside have membranes; ex: nuclear membrane around the inside have membranes; ex: nuclear membrane around the nucleus nucleus (ex. Plants and animals) (ex. Plants and animals)
• AutotrophicAutotrophic – – makesmakes its its own food own food through the process of through the process of photosynthesis (ex. - plants)photosynthesis (ex. - plants)
• HeterotrophicHeterotrophic – – does not make its own fooddoes not make its own food; relies on ; relies on (eats/digest) others for food (ex.- you)(eats/digest) others for food (ex.- you)
• Modes of ReproductionModes of Reproduction– Asexual or Sexual Reproduction– Asexual or Sexual Reproduction
Write these Key Terms in your notes!!!! (words on left)
Here's a simple visual comparison between a
prokaryotic cell and a eukaryotic cell:
Two Types of CellsWrite these on a foldable with 2 flaps or double bubble map
• EubacteriaEubacteriaBoth are prokaryotic – Both are prokaryotic –
which means the only which means the only membrane is on the membrane is on the outside, the organelles outside, the organelles inside don’t have outer inside don’t have outer wallswalls
Archaea or Archaebacteria• Prokaryotic (no nuclear membrane)• Unicellular • Both Autotrophic and Heterotrophic • Oldest living organisms on Earth• Use flagella to move• found in very harsh conditions (such as at the bottom of
the sea or in volcanic vents) • Example: halobacteria

Recap
• The Bacteria kingdom is made up of prokaryotic organisms.
• This means that their cells lack the structure that eukaryotic cells (our cells for example) have, such as a nucleus and mitochondria.
• All the other kingdoms consist of eukaryotic organisms that do have structure to their cells.
The differences between these eukaryotic kingdoms (fungi, plants, and animals) are based on how they
aquire energy to live.• Plants make their own energy from sunlight by
using photosynthesis. (autotrophic)• Animals and fungi are very similar in that they must
ingest other organisms in order to get the energy they need (heterotrophic)
• The main differences are that: animals are mobile and eat food fungi are immobile and absorb their food
(write these in your notes)
The protist kingdom, though also eukaryotic, has little rhyme or reason to it. It consists of mostly single-celled organisms that don't really fit in any of the other kingdoms at all.
