29
organism : an individual form of life such as a plant, animal, bacteria
cell : basic unit of all forms of life
DNA : (deoxyribonucleic acid) substance that carries the genetic information in plant and animal cells
Hypothesis : possible explanation for a set of observations or possible answer to a scientific question
Atom : the basic unit of matter
Electron : negatively charged particle located in the electron cloud
Molecule : collection of atoms bound together
Ion : atom that has a positive or negative charge
Cohesion : attraction between molecules of the same substance
pH Scale : scale with values from 0-14 that measures the concentration of hydrogen ions in a solution
Hydrophilic: water loving
Carbohydrate: compound that is a major source of energy for the body
Activation Energy : energy required to get a reaction started
Catalyst : substance that speeds up the rate of a chemical reaction
Osmosis : diffusion of water through a selectively permeable membrane
Isotonic : concentration of 2 solutions that are the same
Vacuole : organelle that stores materials like water and salts
Heterotroph : organism that gets food or energy by consuming other organisms
ATP : Cellular compound used to store and release energy
Anaerobic : any process without oxygen
Thylakoid : sac-like membranes that contain chlorophyll and carry out Light Dependent Reactions in Photosynthesis
Grana : a stack of thylakoids
Asexual Reproduction : Reproduction with a single parent where the offspring is exactly the same as the parent
Chromosome : Thread-like structure that contains DNA of a cell which is passed down through mitosis
Centromere : center of the duplicated chromosomes
Mitosis : process of cell division where the nucleus is broken down and reformed into 2 nuclei at the end
Cell Plate : membrane that forms between dividing plant cells in order to separate them
Probability : likelihood for something to happen
Hybrid : an offspring from parents with opposite traits; the offspring's traits will then be heterozygous
Phenotype : the physical characteristics presented by genes
