Classification Review Unit Target: Research methods used by scientists to classify organisms.

Learning Target Explain how scientists systematically classify organisms. (knowledge) Classification can best be defined as the grouping of organisms based on their A.similarities. B.differences. C.organs. D.organs systems. A.

Which of the following is not a purpose of classification? A.Organization B.Improved communication C.Saves time D.Increases frustration D.

How did Aristotle classify organisms? A.Using DNA sequences B.Where they lived- land, air, water C.By using colors D.The country they were from B.

True or False? Our current classification system is based on the work of Darwin. False- Linnaeus Today, biologist use newly gained information such as similarities in DNA and evolutionary decent to help them classify organisms. True

List the taxon levels from least specific to most specific. __7__ Genus __1__ Domain __4__ Class __8__ Species __6__ Family __5__ Order __2__ Kingdom __3___ Phylum

Which of the following is NOT true regarding a scientific name. A.It is the same thing as a common name. B.It always includes the genus and species C.The genus name is capitalized and the species name is not. D.It is italicized. A.

Learning Target: Use a dichotomous key to identify species. (skill) See page 511 in your text to practice. Use the first scrimmage to help you review.

Learning Target: Determine the characteristics of domains and kingdoms using a classification table. (skill) Study the chart on page 524. Use scrimmage 2 to help you review.

Learning Target: Compare and contrast prokaryotes and eukaryotes. (knowledge) Prokaryote, Eukaryote or may it pertain to both? No nucleus? Prokaryote Bacteria? Prokaryote Unicellular? May pertain to both A complex cell? Eukaryote

Learning Target: Compare and contrast an autotroph and heterotroph. (reasoning) True or False? An autotroph can turn chemicals and sunlight into usable energy. True A heterotroph can make its own food. False

Which is it? Autotroph or Heterotroph? A snake that eats a frog Heterotroph The bacteria consuming sugar in your yogurt Heterotroph The green algae growing in the turtle tank Autotroph The plant carrying out photosynthesis on the window sill Autotroph The mold decomposing the bread. Heterotroph

Learning Target: Define unicellular and multicellular (knowledge) A single celled organism is ( unicellular / multicellular ) An example of a unicellular organism is ( yeast / bread mold ). An example of a multicellular organism is a ( bacterium / frog )

Learning Target: List and describe the structural levels of multicellular organisms. (knowledge) Put the structural levels of organization used for multicellular organisms in the correct order. __5__ Organ system level __1__ Chemical level __4__ Organ level __6__ Organism level __3__ Tissue level __2__ Cellular level

Which level of organization is it? The basic unit of life Cellular level The tympanic membrane Organ A black bear Organism

Learning Target: Describe the characteristics of the 4 main types of tissue. (reasoning) Match the situation with the type of tissue that would be used. __C__ EpithelialA. My heart pumps oxygen and nutrients to the rest of my body. __D__ConnectiveB. When I touched the stove, I knew it was hot. __A__ MuscleC. The tissue that lines my small intestine absorbs nutrients. __B__ NervousD. My bones support my body.

Name the type of tissue and state its purpose. Type: Nervous tissue Function: Sends and receives messages Hint: These cells have tendrils that connect to each other and other parts of the body.

Type: Muscle tissue Function: Movement Hint: These are long cells that can contract.

Type: Connective tissue Function: Binds skin to underlying organs Hint: The cells of this tissue are far apart. This type has lots of fibers in it.

Hint: Notice the tightly packed cells. This tissue would be found in the outer layer of your skin. Type: Epithelial Tissue Function: This type of epithelial tissue would protect.

Learning Target: Identify organs of the frog. (knowledge) Tympanic membrane

Eye

Skin

Eustachian Tube

Tongue

Small intestine

Stomach

A very full large intestine

Liver

Heart

Is this frog male or female? She is full of eggs.

Learning Target: Match organs with organ systems. (reasoning) Name the organ system associated with the following organs: Mouth, esophagus, stomach, small intestine, large intestine, cloaca Digestive. Kidney, bladder, cloaca Excretory system

Eyes, tympanic membrane, brain, spinal cord Nervous system External nares, glottis, lungs Respiratory system Bones Skeletal system Testes, Ovaries, Oviduct, Cloaca Reproductive system

Learning Target: State the function of each organ system. (knowledge) Integumentary system Skeletal system Muscular system Supports the body and protects internal organs Movement of bones, the heart and hollow organs like the stomach and blood vessels A barrier to germs, controls water loss and regulates temperature

Nervous system Cardiovascular system Immune system Respiratory system Takes in oxygen to be used by cells and removes carbon dioxide from the body Senses and responds to stimuli in the environment Protects the body by fighting infections Transports oxygen and nutrients to cells
