6 Kingdoms

Objective 4.01:

Similarities & differences among the kingdoms

slide2

VOCAB ALERT

Eukaryotic – cell with a defined nucleus and membrane bound organelles.

Prokaryotic – cell without a defined nucleus and lacks membrane bound organelles.

3. Unicellular – organisms made of 1 cell only

Multicellular – organisms made up of many cells.

5. Autotroph – carries out photosynthesis; makes its own food.

slide3

6. Heterotroph – does NOT carry out photosynthesis; must eat food.

Cell Wall – Rigid structure located outside the cell membrane that provides protection and support

Asexual Reproduction - parent cell divides into two identical cells; does not involve gametes; only one parent!!

slide4

9. Sexual Reproduction – involves 2 parents and produces an offspring that is not identical to either parent; involves gametes.

10. Cilia – hair-like extensions that help movement

11. Flagella – Tail-like extension that aids in movement.

characteristics of prokaryotic organisms
Characteristics of Prokaryotic Organisms
  • Unicellular
  • No defined nucleus. They do have a “nucleoid region” where the DNA is located.
  • DNA is organized as a single, circular chromosome.
  • No membrane bound organelles.
  • Do have ribosomes
  • Tend to be smaller than eukaryotic organisms.
characteristics of eukaryotic organisms
Characteristics of Eukaryotic Organisms
  • Multicellular
  • Defined nucleus
  • DNA is organized into multiple, linear chromosomes.
  • Contain membrane bound organelles
  • Do have ribosomes
  • Tend to be larger than prokaryotic cells.
1 archaebacteria
1. Archaebacteria
  • “Ancient” bacteria
  • Prokaryotic Cell (Very Simple!)
  • Unicellular
  • Both autotrophs & heterotrophs
  • Has a Cell wall that lacks peptidoglycan
  • Reproduce asexually
  • Some are motile (can move)
  • Live in extreme environments (Hot, Salty, Acidic)
    • Volcanic hot springs, Salt marshes
2 eubacteria kingdom
2. Eubacteria Kingdom
  • “Recent” bacteria
  • Prokaryotic Cell
  • Unicellular
  • Both autotrophic & heterotrophic
  • Reproduce asexually
  • Some are motile
  • Cell wall has peptidoglycan (thick!)
  • Found nearly everywhere
3 protista kingdom
3. Protista Kingdom
  • Organisms that cannot be classified as an Animal, Plant, or Fungi.
  • Least satisfying of the classifications because members display the greatest variety.
  • 3 Classifications
    • Animal-like Protists: Amoeba, Paramecium
    • Plant-like Protists: Unicellular & Multicellular; Algae
    • Fungi-like Protists: Slime molds & Water molds
3 protista kingdom1
3. Protista Kingdom
  • Eukaryotic
  • Most are unicellular, some are multicellular
  • Autotrophs & heterotrophs
  • Reproduce sexually & asexually
  • Some are motile
  • Some have a cell wall (plant-like)
4 fungi kingdom
4. Fungi Kingdom
  • Eukaryotic
  • Most are multicellular (mushrooms), although some are unicellular (yeast)
  • Heterotrophic: Absorb their food from environment.
    • Feed on dead/decaying organic matter
    • Secrete digestive enzymes into their food source. Absorb the food molecules through their body.
  • Have a cell wall (chitin)
  • Reproduce sexually & asexually
  • Non-motile
5 plant kingdom
5. Plant Kingdom
  • Eukaryotic
  • Multicellular
  • Photosynthetic
  • Autotrophs
  • Have a cell wall (cellulose)
  • Reproduce sexually & asexually
  • Non-motile
  • Includes: Cone-bearing and flowering plants, mosses, & ferns.
6 animal kingdom
6. Animal Kingdom
  • Eukaryotic
  • Multicellular
  • Heterotrophs
  • Reproduce sexually
  • No cell walls
  • Motile, except sponges.
  • Very diverse
