| Question | Answer |
|---|---|
| anything that causes a reaction or change in an organism or any part of an organism | stimulus |
| the maintenance if a constant internal state in a changing envioronment | homeostasis |
| reproduction in which the sex cells from two parnets unite producing offspring that share traits frin both parents | sexual reproduction |
| reproduction that does not invovle the union of sex cells and in which one parent produces offspring identcial to itself | asexual reproduction |
| the passing of genetic traits from parent to offspring | heredity |
| the sum of all chemical processes that occur in an organism | metabolism |
| an organsim that can make its own food by using energy from its surroundings | producer |
| an organism that eats other organisms or organic matter | consumer |
| an organism that gets energy be breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients | decomposer |
| a molecule that is made up of amino acids and that is needed ti build and repair body structures to regulate body structures and regulate processes in the body | protein |
| a class of energy giving nutreints that includes sugars, starches, and fiber contains carbon hydrogen and oxygen | carbohydrates |
| a type of biochemical that does not dissolve in water phats and steroids are lipids | lipid |
| a lipid that contains phosphorus and that is a structural component in cell membranes | Phospholipid |
| major energy-carring molecule in the cell | ATP |
| molecule made up of subunits called nucleotides | nucleic acid |
| protective layer that covers the cell's surface and acts as a barrier | cell membrane |
| structures that perform specific functions within a cell | organelles |
| membrane bound organelle that contains the cells DNA | nucleus |
| single celled organisms that don't have a nucleus or membrane bound organelles | prokaryote |
| organism made up of cells that have a nucleus enclosed by a membrane | eukaryotes |
| rigid structure that gives support to a cell | cell wall |
| organelles that make proteins | ribosomes |
| system of folded membranes in which proteins, lipids and other materials are made | endoplasmic reticulum |
| organelle in which sugar is broken down to produce energy | mitochondria |
| organelle that packages and distributes proteins | golgi complex |
| small sac that surrounds material to be moved into or out of the cell | vesicle |
| organelle that contains digestive enzymes | lysosome |
| group of cells that work together to perform a specific job | tissue |
| group of tissues that work together to perform a specific function | organ |
| group of organs that work together to perform a particular function | organ system |
| anything that can perform life processes by itself | organism |
| arrangement of parts in a organism | structure |
| the task a structure performs | function |
| movement of particles from regions of higher density to regions of lower density | diffusion |
| diffusion of water through a semipermeable membrane | osmosis |
| movement of particles across a cell membrane without the use of energy | passive transport |
| movement of particles across a cell membrane with the use of energy | active trransport |
| the process when the cell surrounds a particle and encloses it into a vesicle and brings it into the cell | endocytosis |
| a vesicle forms around the particle within the cell and the vesicle carries the particles to the cell membrane and fuses with it and then it is released | exocytosis |
| process in which plants capture energy from the sun and change it into food | photosynthesis |
| process that uses oxygen to break down food | cellular respiration |
| process in which cells obatain energy without using oxygen | fermentation |
| the "life cycle" of a cell | cell cycle |
| chromosomes that have the same sequence of genes and the same structure | homologous chromosomes |
| structure in which the DNA is organized in | chromosomes |
| process of chromosome separation | mitosis |
| division of cytoplasm of a cell | cytokenisis |
| the division of organisms into groups or classes based on characteristics | classification |
| the science of describing, naming and classifying things | taxonomy |
| an aid that is used to identify organisms and that consists of the answers to a series of questions | dichotomous key |
| a kingdom made up of bacteria that live in extreme envioronments | Archaebacteria |
| a kingdom that contains all prokaryotes except archabacteria | Eubacteria |
| a kingdom of mostly one celled eukaryotic organisms that are different from plants, animals, bacteria, and fungi | Protista |
| a kingdom made up of nongreen, eukaryotic, organisms that have no means of movement, reproduce with proes, and get food by breaking down other substances in their environment | Fungi |
| a kingdom made up of complex, multicellular organisms that are usually green, have cell walls made of cellulose, cannot move arounf, and use that suns energy to make sugar with photosynthesis | plantae |
| a kindgom made up of complex, multicellular organisms that lack cell walls, can usually move around, and quickly respond to their envioronment | Animalia |
| the passing of genetic traits from parent to offspring | heredity |
| the trait observed in the first generation when parents that have different traits are bred | dominant trait |
| a trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred | recessive trait |
| one set of instructions for an inherited trait | gene |
| one of the alternative forms a gene that governs a characteristic such as hair color | allele |
| and organisms appearance or other detectable characteristics | phenotype |
| the entire genetiv makeup of an organism also the combination of genes for one or more specific traits | genotype |
| the likelihood that a possible event will occur in any given instance of the event | probability |
| a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus which results in the production of sex cells | meiosis |
| one of the pair of chromosomes that determine the sex of an individual. | sex chromosome |
| a diagram that shows the occurrence of a genetic trait in several generations of a family | pedigree |
