Energy & Organisms
| Question | Answer |
|---|---|
| What do the respiratory system and cellular respiration have in common? | Oxygen plays a key role in both. |
| What are the chemical products of cellular respiration? | Carbon dioxide, water, and ATP |
| What is ATP? | An energy-packed molecule that powers living things. |
| Cellular respiration occurs in... | Almost all plants and animals. |
| How does your body get rid of carbon dioxide produced by cellular respiration? | Through your lungs. |
| In which organelles does cellular respiration take place? | Mitochondria |
| Which produces more energy, aerobic respiration or fermentation? | Respiration |
| How do we get the glucose we need to pwer our cells? | Eating |
| In fermentation, what do cells use instead of oxygen to break down glucose? | Carbon dioxide |
| What king of respiration do yeasts use to produce energy? | Anaerobic |
| In what way does plant nutrition differ from human nutrition? | Plants make their own nutrients, but humans must consume theirs. |
| What do plants gain from unlight? | Energy |
| What might happen if plants could not produce glucose? | They could not grow and function. |
| What is the main function of xylem within a plant? | It transporta water and nutrients from the roots to the leaves. |
| Which part of the human body is most similar to stomata in plants? | The lungs and airways. |
| If you were looking for a plants chloroplasts, where would you find them? | In its palisade and spongy cells. |
| What is a pigment? Ex: Chlorophyll and melanin | A substance that contains color. |
| Chlorophyll traps energy from sunlight and stores it as what kind of energy? | Chemical energy. |
| In photosynthesis, water molecules are split into _______ and _________ atoms. | Hydrogen and oxygen |
| an organelle found in plant and algae cells where photsynthesis occurs | chloroplast |
| a green pigment that converts the energy of light into a chemical form that a plant can use. | chlorophyll |
| What are the reactants(used) of phootsynthesis? | CO2, H2O |
| What are the products(made) of phot0synthesis? | C6H12O6, O2 |
| What is the chemical equation for photosynthesis? | H2O+CO2-----> O2+C6H12O6 |
| What are the reactants(used) of photosynthesis? | C6H12O6, O2 |
| What are the products(made) of photosynthesis? | CO2, H2O |
| In what ways are plants and animals dependent on each other? | Plants release oxygen and glucose, which animals need and animals release carbon dioxide and water, which plants need. |
| What is respiration? | the act of breathing |
| What is cellular respiration? | When cells take glucose and turn it into usable energy for a cell. |
| Substances that contain carbon and are produced by living things. Ex: sugar, blood, protein, fat | organic |
| Materials like water, carbon dioxide, oxygen, ammonia | inorganic |
| List 4 functions your body needs energy for. | a)Making lipid membrane. b)Making copies od DNA. c)Making digestive enzymes. d)Moving ions across membrane for nerve impulses. |
| Describe how a butterfly uses and obtains energy differently throughout their life cycle. | First, they get energy from the egg. Then, they hatch into a larva that eats a lot. Pupa obtains no energy. Adults live off energy stored as a larva. |
| What is equlibrium? | A relatively stable amount. |
| Describe how a frog/trout uses and obtains energy differently throughout their life cycle. | First, they use the energy stored in their egg and yolk sac. Adults mainly get their energy by eating. |
| Describe how humans use and obtain energy differently throughout their life cycle, | First, mammals get their energy from their mothers. They get their energy from their mother's milk. Afterward, they eat for energy. Young animals use a lot more energy growing. |
| What does a plant need for photosynthesis other than H2O and CO2? | Sunlight, soil, chloroplasts(cell part), chlorophyll( green pigment) |
| What do organisms need to perform cellular respiration besides glucose and oxygen? | Lungs, water, food, mitochondria. |
| What types of organisms do photosynthesis? | Plants and algae. |
| What types of organisms perform cellular respiration? | Humans, animals, plants |
| Why do many plants stop doing photosynthesis in the fall and winter? | Leaves fall and trees might be covered in snow(hopefully). There's not enought sunlight or water. |
| grass-->grasshopper-->shrew-->owl. What would happen to the grass, grasshoppers and owls is the shrews decreased? | A)owls--decrease B)grasshoppers--increase C)grass--decrease |
| What is a producer? Give an example. | An organism that makes its own food. Ex: Plants, trees, flowers |
| What is a consumer? Give an example. | An organism that get its energy by eating other organisms. Ex: bird, humans, most animals |
| What is a decomposer? Give an example. | An organism that feeds on bodies of dead thigns and fertilizes soil. Ex: mushrooms, fungi, bacteria |
| What is a herbivore? Give an example. | A consumer that eats only plants. Ex:deer, cow |
| What is a carnivore?Give an example. | A consumer that eats animals to get energy. Ex: fox, bear, tiger, lion |
| What is an omnivore?Give an example. | A consumer that eats both plants and animals. Ex: humans, gorilla |
| What is symbiosis? Give an example. | a close relationship between species that benefits at least one of the species. Ex: Any relationship. |
| What is mutalism? Give an example. | A relationship between two species in which both species benefit. Ex: Saguaro and long eared bat: Cactus flowers provide food for the bat. Saguaro's pollen is carried to another plant. Ex: Coli&intestines:yougethelpwith digestion,bacteriagetshomeandfood |
| What is commensalism? Give an example. | A relationship between species in which one species benefits and other is neither helped nor harmed.EX: rat-tailed hawks and saguaro:Hawks have a place to build their nest. Saguaro not affected. EX: Pearlfish uses sea cucumber to hide. Pearlfishputsheadin |
| What is parasitism? Give an example. | A relationship in which one organism lives on or inside another and harms it. EX: Tick- tick lives on a dog and feeds off of blood, dog loses energy and nutrients. EX: Tapeworms and dogs. Tapeworms live in digestive systems of dogs. |
| What is a food chain? Give an example. | a chain diagram showing that one animals eats another plant or animal. EX: grass->prairie dog -> ferret->fox |
| Why are food webs a more realistic way of portraying ecosystems? | they show that other organisms may also eat the same thing. In food chains, only one organism is shown eating each thing. Food webs provide a more elaborate understanding of the transformation of energy for living things. |
