| Question | Answer |
|---|---|
| Organism | Are made of cells, contain similar chemicals and use energy, respond to their surroundings, grow, develop, and reproduce. |
| cells | Are the basic unit of structure and functioning in living things. |
| Unicellular | One cell organisms carries the functions necessary to stay alive |
| Multicellular | Organisms with multiple cells. |
| Stimulus | Any change of signal in the environment that can make an organism react in some way. changes light, sound, flavors, and orders. |
| Response | An action or change in behavior. |
| Spontaneous Generatian | Living things from non living material. |
| Homeostasis | The maintenance of stable internal conditions to stay alive |
| Species | A Specific type of animal that mates and reproduces offspring. |
| Classification | Grouping things based on similarities. |
| Genus | A group of similar, closely related organisms. |
| Binomial Nomenclature | name that indicates its genus and species of shared characteristics. |
| Taxonomy | Study of organisms are classified, names unknown organisms or newly discovered organisms. |
| Domain | Broadest level. Eukarya, Domain Archaea, and Domain Bacteria |
| Evolution | Process of change over time. |
| Convergent Evolution | When organisms evolve within the classification system. |
| 3 Domains that living things are grouped into | Eukarya, Domain Archaea, and Domain Bacteria |
| Cell theory | all living organisms are composed of one or more cells. Life comes from life and that cells are the building blocks of all organisms. |
| characteristics of living things | made of one or more cells, having cellular organization, metabolism, homeostasis, growth and development, response to their environment, reproduction, and ability to adapt through evolution. |
| basic needs of all living things | Oxygen, Water, Food, and Habitat. |
| basic needs are important to living things | They help sustain,survive, and evolve. |
| methods that organisms can use to maintain homeostasis | Humans maintain homeostasis by disposing of salt, urine, sweat, and tears |
| importance of homeostasis in living things | The importance is to stabilize living conditions |
| level of Classification in plants and animals ( in order) | Domain, kingdom, phylum-division, class, order, family, genus, and species |
| level of organization in multicellular organisms | cells, tissues, organs, organ systems, and finally the organism itself |
| Use a taxonomic key to identify the name organisms | domain is flower, kingdom is jellyfish, phylum is sharks, class is koala, order is a feline, family is fox, genus is coyote, and species is wolf |
| Identify scientific names of organisms using the Linnaean naming system | Human: homo sapiens, Lion: Panthera leo, Tiger: Panthera tigris, Dog: Canis lupus familiaris, Wolf: Canis lupus, Cat: Felis cactus, Housefly: Musca domestica, Bottlenose dolphin: Tursiops truncatus’ |
| Identify how Bacteria obtains food, survive and reproduce | Bacteria get energy by making their own food or consuming organic matter. They survive harsh conditions through adaptations and mainly reproduce asexually by binary fission. |
| Identify the helpful role of bacteria in the environmental process | Bacteria play several essential and helpful roles in internal processes, particularly in nutrient cycling, decomposition, bioremediation, and supporting other life. |
| Differentiate among Animal-like protists, plant-like protists, and Fungi- like protists | Amoebas: unicellular, heterotrophs, free-swimming, reproduce asexually/sexually. Red Algae: uni/multicellular, auto/heterotrophs, swim or attach, sexual/asexual. Slime molds: unicellular colonies, heterotrophs, move, asexual. |
| Explain how fungi can be helpful and harmful | Some fungi are helpful in making food like bread or medicine, chemicals used in dyes or perfumes and deodorant. Some produce poisons or allergic reactions, break down dead wood and make nutrients available for living creatures. |
| Describe the characteristics of vascular plants | By internal transport system of xylem and phloem True roots, stems, and leaves, with lignin providing structural support |
| Identify and describe the two vascular tissues that transport materials throughout a vascular plant | Xylem which transports water and minerals from roots upwards and provides structural support. Phloem which moves sugars and organic molecules from the leaves to other parts of the plant. |
| Identify the helpful and harmful role of Bacteria in environmental processes | Environmental processes, contributing significantly to nutrient cycling, decomposition, bioremediation, and ecosystem health |
| Explain the functions of the leaf | Stoma a small opening on the underside of a leaf through which oxygen, weather, and carbon dioxide can move. It also prevents water. The two main functions are to capture light energy and gas exchange. |
| Explain the functions of the stem/branches | Provides support and stores food for the plant. Stems also connect roots to leaves, so leaves can get the water they need to carry out photosynthesis. |
| Explain the functions of the root | Three main major functions, first roots absorb water and nutrients from the ground, Second roots anchor the plant to the ground, Third roots store food and nutrients. |
| Name and describe the three main types of symmetry that can be found in living organisms: Asymmetrical | Animals without symmetry, such as a sea sponge. |
| Name and describe the three main types of symmetry that can be found in living organisms: Radial Symmetry | Animals with this symmetry such as a jelly fish, live in weather and have complex body plans with tissue and usually have organ systems. Animals with symmetry if many imaginary lines drawn through a center point divide the body into two mirror images. |
| Name and describe the three main types of symmetry that can be found in living organisms: Bilateral Symmetry | Most animals, such as a horseshoe crab, have bilateral symmetry. Only one line can be drawn to divide the body into halves that are mirror images. |
| Name and differentiate the symbiotic relationship among living organisms: Vascular | true root, stem, leaves. and non vascular plants: No true root, cell layers are thick, Cell walls are things which prevent them from gaining height. |
| Name and differentiate the symbiotic relationship among living organisms: Prokaryotes and Eukaryotes | Eukaryotes are big complex cells that have a nucleus that can be unicellular or multicellular such as animals, plants, and fungi. Prokaryotes are small simple cells no nucleus like bacteria |
| Name and differentiate the symbiotic relationship among living organisms: Unicellular and Multicellular organisms | Unicellular are organisms that are only made up of one cell while Multicellar organisms are organisms that are made up of multiple cells |
| Name and differentiate the symbiotic relationship among living organisms: vertebrates and invertebrates | Vertebrates are organisms with a backbone, and invertebrates are organisms without a backbone. |
| Name and differentiate the symbiotic relationship among living organisms: Ectotherms and Endotherms | Ectotherm are Organisms like amphibians and reptiles that produce little body heat and Endotherms are organisms that can control their internal heat and regulate their own temperature like mammals and birds |
