| Question | Answer |
|---|---|
| ADAPT and Evolve | This owl has a disk-shaped face, large eyes to see in the dark, excellent hearing, silent feathers, and sharp talons. All of these traits help this animal survive. Which characteristic of life does this demonstrate? |
| Obtain and use ENERGY | The grass does photosynthesis, then the grasshopper eats the plant. After that, the frog eats the grasshopper, and then is eaten by the snake. Finally, the hawk eats the snake. When the hawk dies, fungi will decompose the body of the hawk. |
| Movement | This characteristics is commonly assumed to be a characteristic of all living things, but really is not. |
| Have Universal Genetic Code (DNA) | All cells in all organisms, both unicellular and multicellular, contain genetic material inside that tells cells how to make proteins. This information is passed on from parents or parent cells. |
| RESPOND to stimuli (Environment) | You go to grab a pan, but it is hot. You feel pain, quickly let go, and scream, "Ouch!" Which characteristic of life is demonstrated in this scenario? |
| GROW and DEVELOP | Frog eggs hatch into tadpoles. Tadpoles grow back legs first. Then they grow front legs and the tail disappears. They start breathing with lungs instead of gills. When the tail is gone the frog is an adult. The cycle can then repeat. |
| REPRODUCE | This hen (female chicken) laid many eggs, and now she is a busy mama! Which characteristic of life is this? |
| Obtain and use ENERGY | This plant uses sunlight to produce its own food by a process called photosynthesis. Which characteristic of life is this? |
| Made of CELLS | Animals, people, plants, protists, fungi, and even bacteria are made up of these. Which characteristic of life is this? |
| Have DNA | Yes that little girl is the woman's daughter, and they look very similiar. This is what makes children look like their parents. What characteristic of living things makes the daughter look so much like her mother? |
| Adapt and EVOLVE | Some organisms are no longer alive on earth, but we know they once existed because we can see their fossils. They did not survive because they could not change as quickly as the environment did. |
| GROW and develop | Plants start to germinate from a seed, and then get bigger and bigger until they are full grown plants. What characteristic of life is this? |
| REPRODUCE | Bacteria make more bacteria by dividing into two separate cells. Then those divide to create more and more bacteria cells. This division is called mitosis. Which characteristic of life is this? |
| RESPOND to stimuli | When a bright light shines in our eyes our pupils (black part) get smaller. We might feel a little bit of pain at first. Which characteristic of life is this? |
| Adapt and EVOLVE | Millions of years ago, horses were not big like they are today. Over millions of years these populations have changed based on changes in their environment over time. Which characteristic of living things does this picture show? |
| REPRODUCE | Pollen (male sex cells) in plants must join with the ovule (female sex cell) in the same or another plant to produce seeds. The seeds become new plants. Which characteristic of life is this? |
| Homeostasis | Living things do this to keep a balance inside of their bodies and cells. The body has a way to keep the same temperature inside our bodies. |
| Metamorphosis | Some living things look completely different when they are born and when they are adults. What is it called when an organism changes form during its lifetime? |
| Asexual reproduction | This means that one organism makes more of its own kind with only ONE set of genetic information. |
| Sexual reproduction | This means organisms make more of their own kind using two different sources of DNA. The offspring have a combination of the DNA of both parents, but does not have the exact DNA of either parent. |
| Heterotroph | An organism that must get energy by eating another organisms or organic materials. For example, cows eat grass. Frogs eat insects. Fungi consume dead materials. |
| Autotroph | An organism that gets energy by making their own food. For example, plants do photosynthesis by using the suns energy to make glucose. They use that glucose for energy to grow and reproduce. |
| Homeostasis | A Jackrabbit is a desert mammal. The jackrabbit's circulatory system increases flow of blood to the ears on hot days and decreases circulation on at night or on cool days. This circulation pattern is an example of which characteristic? |
| Fight or Flight (Respond to Stimuli) | Animals signalling to others that danger is in an area allows all to either run or stay as and defend themselves. This innate ability is an example of what trait? |
| Autotroph Examples | Fern, euglena, some bacteria |
| Heterotroph Examples | humans, leopards, mushrooms, some bacteria |
