Name:_____________________________________Date:_________Period:_____ Study Guide –Answer the following questions to help review for the quiz. Part A 1. What are the five characteristics of living things? Explain. Hint: Mustard Lab a. Made of cells- A cell is the smallest unit of life. It is membrane covered structure that contains the materials needed to perform life functions. ex. Skin cells b. Respond to their environment- ability to sense change in their environment & respond to that change. Ex. Mustard seeds grew in the light c. Reproduce- pass copies of all or part of their DNA to their offspring. Can be done sexually (two parents) or asexually (one parent) ex. Human reproduction. d. Use Energy- Needed to carry out everyday functions, such as breaking down food and repairing/building cells. Ex. Eating a healthy breakfast e. Grow & Mature- All organisms change over time. Unicellular organisms divide. Multicellular organisms the # of cells increase and the overall body size increase. Some organisms have different maturation stages ex. Tadpoleď frog. 2. List the four necessities of life that almost all organisms need to survive. a. Water b. Air c. Food d. Shelter 3. What is a stimulus? Define and give an example. Anything that causes a reaction or change in an organism or any part of an organism. Ex 1. Hunger -> Salivate Ex 2. Light -> Plant growth 4. Define homeostasis Maintenance of a stable internal environment. Ex. Shivering when cold 5. What is the difference between an autotroph and heterotroph? Give an example of each Autotroph- produces its own energy using light, water, carbon dioxide, or other chemicals. Ex. Plants, Bacteria Heterotroph- obtains energy by consuming other organisms. Ex. Animalia Part B 1. What part of the words “binomial nomenclature” means “2?” bi 2. How is your first and last name an example of binomial nomenclature? 2 names- first and last are like the 2 names genus and species 3. How many names does an organism get in our modern classification system? 8 4. Which layer of our modern classification system is most specific? species 5. List the three domains. Archaea, Bacteria, Eukarya 6. What is the domain that includes extremophiles; bacteria that live in harsh environments? Archaea 7. What is the domain that includes bacteria that live where we live? Bacteria 8. Write your genus and species name correctly! Homo sapiens 9. What are the four kingdoms under the domain Eukarya? Protista, Animalia, Plantae, Fungi 10. The classification of a cat is, Eukarya, Animalia, Chordata, Mammalia, Carnivora, Felidae, Felis, domesticus. a. What is the cat’s order? Carnivora b. What is the cat’s phylum? Chordata c. What is the cat’s class? Mammalia d. What is the cat’s scientific name? Felis domesticus 11. Organisms that share scientific names are related. The more names in common, the more closely related the organisms are. Level Human Wolf Bullfrog Brine Shrimp Domain Eukarya Eukarya Eukarya Eukarya Kingdom Animalia Animalia Animalia Animalia Phylum Chordata Chordata Chordata Arthropoda Class Mammalia Mammalia Amphibia Crustacea Order Primates Carnivora Anura Brachiopoda Family Homonidae Canidae Ranidae Anostraca Genus Homo Canis Rana Artemia species sapien Lupus catesbeiana Gracillus 12. In the classification chart, above, which organism is least related to the others? Brine Shrimp- Artemia gracillus Two most closely related? Human and Wolf from Mammalia 13. If you found an organism that had a nucleus, was multicellular, and was a heterotroph/decomposer, to which kingdom would it belong? Fungi 1a. No nucleus……………………………………………………… Go to 2 1b. Nucleus…………………………………………………………… Go to 3 2a. Cell walls contain a compound called peptidoglycan…………………………………………………. Eubacteria 2b. Cell walls do not contain the compound peptidoglycan…………………………………………………. Archaebacteria 3a. Single celled…………………………………………………….. Protista 3b. Multicellular…………………………………………………….. Go to 4 4a. Autotroph (producer)………………………………………. Plantae 4b. Heterotroph (consumer)………………………………….. Go to 5 5a. Bread down and absorb rotting organisms……….. Fungi 5b. Eat other organisms………………………………………….. Animalia
