multicellular

unicellular

Which term means that the organism produces its own food? Consumes food?

autotroph

heterotroph

Vocabulary

Prokaryotic – describes an organism with cells that have a cell membrane but do NOT have a nuclear membrane

Eukaryotic – describes an organism with cells that have a cell membrane and a nuclear membrane

Vocabulary

Autotrophic – makes its own food

Heterotrophic – gets nutrients from the food it consumes

List of the Three Domains and the Six Kingdoms

1. Domain Bacteria– Kingdom Eubacteria

2. Domain Archaea– Kingdom Archaebacteria

3. Domain Eukarya– Kingdom Protista

– Kingdom Fungi

– Kingdom Plantae

– Kingdom Animalia

The grouping of organisms into KINGDOMS is based on 3 factors:

– 1. Cell Type – 2. Cell Number – 3. Feeding Type

6

1st Criterion for Kingdom Divisions: Cell Type

Prokaryotes or Eukaryotes

7

6 kingdoms

1. Eubacteria2. Archaebacteria

3. Protista4. Fungi5. Plantae6. Animalia

Prokaryotes

Eukaryotes

8

2nd Criterion for Kingdom Divisions: Cell Number

•Unicellular- single celled organism –protozoans, bacteria, some algae

•Multicellular- many celled organism –cells start to specialize/differentiate

9

Unicellular • Multicellular

10

3rd Criteria for Kingdom Divisions: Feeding Type

–Autotroph or ProducerMake their own energy source

–Heterotroph or ConsumerMust eat other organisms to surviveIncludes decomposers – those that eat dead matter!

11

Kingdom Eubacteria

Bacteria can live in many places on earth, inhabiting a wide variety of habitats, including other organisms

Unicellular

Prokaryotic

Autotrophic or heterotrophic

Thick cells walls

Kingdom Eubacteria

Bacteria come in different shapes, such as round, spiral and rod-shaped.

Kingdom Eubacteria

Bacteria can cause a wide variety of diseases, such as strep throat, food poisoning and the Black Death (bubonic plague of the Middle Ages)

Kingdom Archaebacteria

Bacteria that live in extreme habitats, such as hot springs, geysers, volcanic hot pools, brine pools

Unicellular

Prokaryotic

Autotrophic or heterotrophic

Characteristics-Shapes

Shapes:– Cocci- round– Bacilli- rod-shaped– Spirilla- spiral

16

Kingdom Protista

Extremely diverse group

Eukaryotic

Most unicellular, some multicellular

Autotrophic and heterotrophic

Cells transforms food into energy

Are organisms with nuclei in their cells that do not fit into the fungi, plant, or animal kingdoms but may have characteristics of each.

Protozoa Animal-like protist

First animals

They share some characteristics with animals.

Can’t make their own food

Take food from surroundings.

Move through environment (slip and slide like jelly, use tail-like or fine hairs)

Live wherever there is water

Found in moist soil and inside other organisms

Kingdom Protista

Volvox – a colonial protist

Euglena - autotrophic

A slime moldAmoeba - heterotrophic

Kingdom Fungi

Eukaryotic

Most are multicellular

Heterotrophic (decomposers)

Cell walls made of chitin

Absorbs nutrients from their environment to make food.

Decompose (break down) the tissues of other organisms

Can not move from place to place

Can grow very quickly

Kingdom Fungi

Stilton cheese

Bread mold

Kingdom Plant

Eukaryotic

Multicellular

Autotrophic

Cell wall of cellulose; chloroplasts present

Kingdom Plantae

Kingdom Animalia

Eukaryotic

Multicellular

Heterotrophic

No cell walls, no chloroplasts

Kingdom Animalia

Coral snake

Sponge

Flatworm

Octopus

Jellyfish

Bear
