1. Diversity of Organisms

2. Six Kingdom System
Archaea
Eubacteria
Protists
Fungi
Animals
Plants

3. Archaea & Eubacteria Unicellular, microscopic
Prokaryotic- No nucleus or membrane bound organelles
Some are Photosynthetic
Autotrophs
Ex. cyanobacteria,
Saprophytic or parasitic
Heterorophs
Saprophytic: feed on dead substances
Parasitic: obtain nutrients from living organisms

4. Protists- 2 Kinds Protozoa Unicellular; microscopic No cell wall
Nucleus present
Eukaryotic – complex cells
Autotrophic = makes its own food Heterotrophic = must go get its food
Algae- the only ones with cell walls, some multicellular; all photosynthetic

5. Fungi Eukaryotic Made up of hyphae- slender threads
Mycelium: a mass of hyphae
No root, stem and leaf
No chlorophyll
Saprophytic or parasitic
Reproduce by forming spores
Cell walls made of Chitin

6. Animals -heterotrophic, have to move to get their food -Multicellular
Eukaryotic – complex cells with nucleus and organelles
Divided into two groups according to the presence or absence of backbone:
Invertebrates : without backbone
Vertebrates : with backbone

7. Invertebrates Many different body plans! No backbone
May or may not have an exoskeleton
Includes sponges, echinoderms, crustaceans, mollusks, worms, as well as several other type organisms

8. Invertebrates

9. Invertebrates

10. Vertebrates Divided into 5 groups: Fish Amphibians Reptiles Birds
Mammals

11. Fish Aquatic – fresh and salt water Cold-blooded – 2 chambered heart
Body covered with wet and slimy scales
Streamlined body to move easily through water
Fins for balance and to control movement
Gills for breathing
External fertilization

12. Amphibians Cold-blooded – 3 chambered heart Moist, scaleless skin
Limbs present
tetrapods
Larvae (tadpoles) use gills for breathing; adults use lungs & skin
External fertilization
No claws on toes

13. Reptiles Cold-blooded – 3 or 4 chambered heart
Body covered with dry, hard scales
Live on land
Breathe with lungs
Internal fertilization; lay shelled eggs
Claws on toes

14. Birds Warm-blooded – 4 chambered heart Body covered with feathers
2 wings and 2 feet
Beak for feeding
Lungs & air sacs for breathing
Internal fertilization; lay shelled eggs
Claws on toes

15. Mammals Warm-blooded – 4 chamber heart Hair or fur on skin
Females have mammary glands for producing milk
Lungs for breathing
Internal fertilization; embryos develop inside mothers’ bodies
Give birth to offspring
Claws or nails on toes

16. Plants
Eukaryotic
Most plants contains photosynthetic pigments (e.g. chlorophyll) for photosynthesis
Autotrophic: makes own food
Cell walls
Multicellular
Reproduce by spores or seeds
Transport by vascular tissue- xylem & phloem

17. Xylem and Phloem make up the vascular bundles.
xylem - located on the innermost ring of the stem/root; it carries water and minerals from the roots to the rest of the plant.
phloem - located on the outermost ring (of vascular tissue) in the stem/root; it carries dissolved proteins, amino acids, sugars and other complex compounds in any direction.
Xylem and Phloem make up the vascular bundles.
