Monera Protista Fungi Plantae Animalia
1. Monera
Simplest organisms, one celled, prokaryotic Found everywhere on earth, some are helpful, some harmful, consumers They need water , oxygen and appropriate temperature to survive Most feed on dead plants & animals Most do not move (non-motile) Asexual reproduction by binary fission (1 2) Sexual reproduction by conjugation
Cell Parts

cytoplasm

cell membrane cell wall some have flagella Cell Shapes
Round
(coccus, cocci)
Rod-Shaped
(bacillus, bacilli)
Spiral
(spirillum, spirilli)
Different Types of Bacteria
2. Protista
Most one celled organisms, eukaryotic, most live in water
PROTOZOA
– animal-like, move, consumers one-celled, (don’t make food)
ALGAE
– plant-like, most one-celled, have chlorophyll, producers (m ake food)
SLIME MOLDS
– fungus-like, one-celled, have 2 life stages (1 fungus-like life stage), consumers Amoeba Examples
Kingdom
PROTISTA
Asexual reproduction by (individual breaks into pieces & each piece grows into a new individual) fragmentation Sexual reproduction by alternation of generations
3. Fungi
Multi-cellular, eukaryotic organisms Most have large cells and many nuclei Fungi have cell walls made of chitin They are consumers, and grow in dark moist places Asexual reproduction by budding (buds re grow to adult) & fragments (fragments grow to new adult) Sexual reproduction by spores (spores germinate and produce new organism
Kingdom
FUNGI
4. Plantae
Many-celled, eukaryotic Have cell walls made of cellulose Contain chlorophyll, they are producers (make their own food though photosynthesis) Live in both aquatic & land environments Plants do not move Examples include: mosses, ferns, grasses, shrubs, flowering plants (angiosperms), trees (gymnosperms)
Kingdom
PLANTAE
5. Animalia
We will look at 9 phyla (plural of phylum)

Mollusks Arthropods Echinoderms Chordates
Phylum:
Porifera (Sponges)
1. Porifera
(Sponges) Simple organisms 2 cell layers No head or mouth, no organs digestion by diffusion Porous body with stiff skeleton Attached to underwater surfaces Live in fresh water and salt water No symmetry
Phylum
Coelenterata
2. Coelenterata
(jellyfish, sea anemones, sea fans, corals) 2 cell layers Tentacles around the mouth Tentacles have stinging cells Mouth is the only opening into the digestive cavity Have radial symmetry Most live in salt water Nerve net (no head)
Phylum
Platyhelminthes
3. Platyhelminthes
(Flatworms) (flukes, tapeworms, planarians) 3 cell layers Mouth is the only opening into the digestive cavity Many are parasitic (flukes, tapeworms) Many live in the ocean (planarians) Exhibit bilateral symmetry Primitive brain, 2 longitudinal nerve cords, respond to stimuli (touch, light)
Phylum
Nematoda
4. Nematoda
(Round Worms) (hookworms, pinworms, trichinae) Have tubular body Have digestive tract with 2 openings Live mainly in the soil, water or animal tissues Reproduce sexually Exhibit bilateral symmetry Primitive brain, pharyngeal nerve ring, dorsal and ventral nerve cords
Phylum
Annelida
5. Annelida
(Segmented Worms) (earthworms, sandworms, leeches) 3 cell layers Segmented body with pair of bristles on each segment Have circulatory, digestive & nervous systems (breathe through skin) Sensory cells, more advanced brain, ventral nerve cord with ganglia Move by contracting circular and longitudinal muscles
Phylum
Molluska
6. Mollusca
(snails, slugs, oysters, clams, octopuses, squids) 1.
2.
3.
3 distinct body parts Head-foot Heart and organs Mantle Have soft body protected by 2 shells or no shell 1 shell , Live in fresh or salt water, or on land
Phylum
Arthropoda
7. Arthropoda
Have jointed legs, segmented bodies & exoskeleton, have bilateral symmetry They live in the water, land and air The 5 major classes include: 1. Crustaceans (Lobsters, crabs, crayfish, shrimp) 2. Arachnids – 8 legs, 2 body parts (Spiders, mites, ticks, scorpions) 3. Insects – 6 legs, 3 body parts (Beetles, grasshoppers, dragonflies, butterflies) 4. Centipedes & 5.
Millipedes
Phylum
Echinodermata
8. Echinodermata
(starfish, sea urchins, brittle stars, sand dollars, sea cucumbers) Have 5 body parts (“arms”) radiating out Have bumpy, spiny internal skeleton Have “tube feet” Live in salt water on ocean bottom Exhibit radial symmetry
Phylum
Chordata
Kingdom: Animalia
9. Chordata
Phylum
All chordates have: 1.
Gill slits (they stay or disappear) 2.
Notochord (supporting rod of tissue along the back) 3.
Hollow nerve tube (runs along the back) Most chordates have a back bone
(Fish, Amphibians, Reptiles, Birds, Mammals)
Some chordates do not have a back bone (Tunicates and Lancelets)
Classes
Fish – live in water, breathe through gills, are covered by scales, and are cold-blooded Amphibians – live in moist environment, in or near water, or on land for short periods, have thin moist skin, and are cold-blooded Reptiles have dry scaly skin, are cold-blooded Birds – live on land & over H2O, have feathers, fly, breath through lungs, warm-blooded Mammals – live on land and in or near water, have hair, fur, females have mammary glands that produce milk for young. They lay eggs, or have pouches, or develop in the mother (live birth).
