Biology Exam Peerenb
Semester 1
| Question | Answer |
|---|---|
| diffusion of molecules (movement) through a semi-permeable membrane from a high concentration to low concentration | osmosis |
| surrounds all lining cells, most important organelle; lets things in and out of cell | cell membrane |
| only in plant cells; rigid, holds everything together | cell wall |
| does not allow things to pass through | non-permeable |
| allows certain things to pass through the cell membrane, but not others | selectively permeable |
| transport of a substance across a cell membrane diffusion; doesn't need energy | passive transport |
| transport of a substance across the cell membrane against the concentration gradient and requires energy | active transport |
| state of balance | equilibrium |
| The process by which an organism keeps its internal environment in a constant condition despite changes in its external | homeostasis |
| substance that dissolves in another (ex. salt is the solute in salt water) | solute |
| substance that that dissolves the solute (ex. water) | solvent |
| greater concentration of solute outside of the cell wall | hypertonic |
| lower concentration of solute outside the cell wall | hypotonic |
| equal concentration inside and outside of the cell | isotonic |
| homogeneous mixture of 2 or more substances; cannot be separated. Becomes a new substance.(Kool aid + water) | solution |
| can be separated (ex. Chex Mix) | mixture |
| has a nucleus | eukaryotic |
| no nucleus | prokaryotic |
| single cell; does everything by itself | unicellular |
| made of many cells; working together | multi-cellular |
| can divide and differentiate and become specialized cells | Stem cells |
| control central of the cell | nucleus |
| a group of cells working together (ex. muscle tissue) | tissue |
| Structures that have a specifi c function and are made up of different tissues. (stomach) | organ |
| Groups of organs that have related functions.(ex. digestive system) | organ system |
| specialized structure of a cell (ex. nucleus, mitochondria) | organelle |
| The watery fluid that contains the organelles of the cell | cytoplasm |
| for growth and repair of tissue, immune system, found in citrus fruits (oranges0 | Vitamin C |
| eyes, skin, hair, immune system; found in carrots, sweet potatoes | Vitamin A |
| needed for breathing and respiration. Breathe; inhale | oxygen |
| provides energy to body; starches and sugars | carbohydrate |
| mineral found in the blood; helps carry oxygen | iron |
| building blocks of protein, helps body function properly, get it from eating proteins (meat, eggs) | amino acid |
| helps with temperature; helps transport nutrients throughout the body | water |
| balances pressure between cells; Electrolytes affect the amount of water in your body, the acidity of your blood (pH), your muscle function | electrolytes |
| needed for strong bones & teeth | calcium |
| helps with calcium absorbtion, needed for bones ; can come from the sun and some foods | Vitamin D |
| needed for metabolism and thyroid function; w/o enough you can get a goiter (enlarged thyroid in neck) | iodine |
| protects cells; helps immune system found in vegetables, oils | Vitamin E |
| studies interactions between individual organisms and their environments | ecology |
| eats meat | carnivore |
| eats both meat and plants | omnivore |
| eats plants | herbivore |
| the hunter | predator |
| the hunted | prey |
| is a contest between organisms, animals, contest between individuals, groups, etc., for territory, a niche, or a location of resources, for resources and goods | competition |
| symbiotic relationship in which both organisms benefit (bee gets pollen and flower gets pollinated/reproduction) | mutualism |
| symbiotic relationshiop in which one organism benefits, the other is neither helped nor harmed (clown fish & anenome) | commensalism; |
| symbiotic relationship in which one organism is helped and the other is harmed (dog is harmed, flea is helped) | parasitism |
| amount of different life forms in an ecosystem or habitat | biodiversity |
| non-living; air, water temperature | abiotic factors |
| living factors; types of plants, animals, etc. | biotic factors |
| a group of organisms that look alike and can breed with other members of the group & produce offspring | species |
| a group of organisms of the same species that live in a particular location | population |
| groups of organisms living together in a certain area. They interact and depend upon one another for survival. | community |
| all living and nonliving things in a given environment | ecosystem |
| community of plants and animals living in a certain climate (tundra) | biome |
| organism that must get its food from eating other organisms | consumer |
| organism that produces its own food (plants) | producer |
| An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition.(dragonflies) | indicator species |
| a series of interlocking food chains. They show the transfer of energy throughout an ecosystem. | food web |
| building block of life; smallest unit of structure and function in living things. | cell |
| have cell wall and chloroplasts (for making food=photosynthesis) | plant cells |
