Title: Biodiversity

  • Mrs. Zazzali
  • Room 205

What is an organism?
  • Any living thing that reproduces, grows, and
    adapts to its surroundings. Ex. Animals,
    Plants, Fungus, Protists, and Bacteria.

What is a habitat?
  • Place where an organism lives depending on the
    organism ex. Monkey lives in the jungle
  • Where a species finds food
  • Natural home or shelter of an animal
  • Lives according to their needs
  • Adapts and responds to environment
  • And carries out life processes!

What should I know about Taxonomy?
  • Taxonomy-the science of naming and classifying
    organisms (Thank you Linnaeus!)
  • All Taxonomic Categories go from the most broad
    category to the most specific and include

Taxonomic Category Mnemonic/trick to help you remember
Kingdom King
Phylum Phillip
Class Came
Order Over
Family For
Genus Great
species Spaghetti
The Scientific Name-Avoid the confusion!
  • Scientists refer to organisms with their
    Scientific Names to avoid confusion, a universal
    language. Remember all the confusion when I
    asked you to find the difference between a
    cougar, puma and mountain lion. You know now
    that they are really the same organism or animal
    known Scientifically as Puma concolar!

Scientific Name cont.
  • Scientific Name is made of the Genus and species
    name. The first letter in the Genus is always
    spelled with an upper case letter and the species
    first letter is always lower case. The species
    is the most specific taxonomic category.
  • Examples

Genus species
Homo sapien
Canis familiaris
Panthera leo
Lesson 2
  • Compound Light Microscope- Uses 2 lenses and
    light to make a specimen visible. Look over your
    Microscope worksheet, know the parts
  • Dry-Mount Slide- A microscope slide on which no
    water is used. (Our WOWBug slides)

WOWBug and insect parts
  • Head- 1st body segment in insects (contain eyes,
    antennae and mandibles or jaw)
  • Thorax- 2nd body segment in insects, between the
    head and abdomen
  • Abdomen- A segment of the body of many animals,
    the third body segment in insects

Microscope Views of Specimen-Bonus/Challenge words
  • Lateral- side view of a specimen
  • Ventral- abdominal view of a specimen
  • Dorsal- back view of a specimen

Lesson 3 Investigating Lumbriculus variegatus
or the Blackworm
  • What did you learn?
  • Blackworms can regenerate both head and tail to
    break free from predators.
  • Lives in Ponds, Marshes and Lakes in N. America,
    and Europe.
  • Contain male and female sex organs.
  • Tail end used for sensing.
  • Can have 150250 segments.
  • Under a microscope, you can monitor their pulse
    in bpms.

Key Vocabulary
  • Anterior toward the front, or head, of an
    animal body.
  • Posterior toward the back end of an animal.
  • Regeneration process by which organisms produce
    new body parts.

Lesson 4 Vocabulary
  • Ecosystem- A community of organisms interacting
    with their abiotic environment.
  • Macroorganism- An organism that can be seen with
    out magnification, usually greater than 2 mm.
  • Microorganism- An organism that can not be seen
    with out magnification.
  • Habitat- A place where an organism naturally

Lesson 5 Vocabulary
  • Cell The basic unit of life
  • Organelle a well-defined structure found in a

Animal Cell Key Parts to know
  • Cell Membrane outer boundary that protects and
    allows materials to move in and out
  • Nucleus The boss or CEO of the cell, the
    control center
  • Mitochondria Mighty Mitochondria is the
    powerhouse or energy in the cell
  • Ribosomes Make Protein
  • Endoplasmic Reticulum The super highway or
    folded membrane where you find the ribosomes
  • Cytoplasm Gel-like substance that houses the

Plant Cell Key differences
  • Cell Wall extra rigid layer of protection made
    of cellulose
  • Chloroplast/chlorophyll- gives pigment to the
    plant and helps trap energy from the sun in
  • Vacuole- much larger in plants, the storage
  • Visit for some practice!

Lesson 6 Protists and other Microorganisms
  • Kingdom Protista- one or many celled and
  • Eukaryotic- Contain a nucleus and other membrane
    bound organelles, 4 Kingdoms of Life are
    Eukaryotic including Protists, Fungi, Plants
    and Animals
  • Prokaryotic- Contains no nucleus or membrane
    bound organelles, 2 Kingdoms are Prokaryotic
    including Eubacteria and Archaeabacteria

Bacteria- Single celled and Prokaryotic
  • Good- Help your digestive and immune system,
    probiotics, give plants nutrients, help make
    medicine like antibiotics Mostly good only
    sometimes bad
  • Bad- cause disease or illness like Streptococcus
    or Salmonella
  • Two Kingdoms of Bacteria include Archaebacteria
    and Eubacteria

Lesson 7
  • Vertebrate- Animal with a backbone
  • Invertebrate- Animal with out a backbone
  • Classes of Vertebrates
  • Mammalia-warm-blooded animals with hair/fur and
    can nurse their young
  • Aves- warm-blooded with feathers/hollow bones
  • Reptilia- cold-blooded w/scales lay eggs on
  • Pisces- cold blooded, live in water, divided into
    jawless, cartilage and bony fish
  • Amphibia- cold-blooded part of life in water and
    land, breathe through gills when young and lungs
    as adults, lay eggs in water

Lesson 9 - Daphnia
  • All about Daphnia- otherwise known as The
    Transparent Water Flea (pp 132-133)
  • Jointed Limbed Arthropod
  • Crustacean
  • Transparent Exoskeleton make them easy to study
  • Live in Freshwater
  • Important Food source for many organisms like
    Fish, important link in the food chain

Lesson 10 The Hydra
  • Hydra belong to the phylum Cnidaria, also called
    Cnidarians because they can sting
  • Freshwater organism
  • Tube like body with Tentacles
  • Tentacles draw up food
  • Asexual Reproduction known as budding, a new
    organism is produced from the body of another

Lessons 11 12
  • What do you know about the Fungi Kingdom?
  • Eukaryotic
  • Single or Multi-celled
  • Yeast are Single-celled
  • Reproduce Asexually and Sexually
  • Feed on other organisms
  • Decomposers
  • Fungi Parts Umbrella-shaped Cap (Reproductive
    structures), Mycelium, Hyphae that absorb and
    digest food, Sporangia (give color), Spores
    (Travel through the air)

  • Decomposers- an organism like bacteria or fungi,
    that breaks down dead plants and animals into
    simpler substances
  • Fermentation- when yeast feed on dough, they
    reproduce and excrete or produce Carbon dioxide
    and alcohol.
  • Respiration- The yeast then eat the alcohol and
    use Oxygen to turn its energy into fuel for
    growth and reproduction.
