Advanced Placement Biology Summer Assignment 2010-2011 School Year Below is a list of terms, prefixes, and suffixes that are commonly used in Biology. By knowing these terms before the class starts, you will be at a significant advantage. Over the summer, become familiar with these terms, and prepare for a quiz over these on the first day. I would suggest making vocabulary cards to study. If you have any concerns or questions you can email me at kelly.shaw@metcalfe.kyschools.us. I will check my email weekly over the summer. A-,an- absence of something, without Ab- away from Abiotic- nonliving Acid- substance that releases protons in solution Active site- region of the enzyme that the substrate binds to Active transport- transport of a substance across a membrane that requires energy Aerobic- requires oxygen; in the presence of oxygen Allele- alternate form of a gene Amino acid- monomer of a protein Amphi- on both sides; of both kinds Anabolism- metabolic process in which complex molecules are formed from simpler molecules Anerobic- absence of oxygen, process that does not require oxygen Ante- preceding, before Anion- negatively charged ion Ant-, Anti- opposed to; Apical- pertaining to the apex or tip of something; usually a plant Ase- suffix that indicates the substance is an enzyme Atom- smallest unit of a chemical element, consists of a protons, electrons, and neutrons. Autosome- chromosome that codes for all traits except for gender Bacillus- rod shaped bacteria Base- substance that can accept a hydrogen ion in solution; opposite of an acid Bi- two Bio- life Bilayer- in membranes a structure that is two lipid layers thick Biomass- total weight of all the living organisms Biosphere- synonym for Earth Biotic- living Caput- head Carbohydrate- organic compound with a 1:2:! ratio of C, H, O Cardio- heart Catabolism- metabolic process in which complex molecules are broken down into simpler molecules Cation- positively charged ion Cephalo- head Coccus- spherically shaped bacterial cell Complementary Base Pairing- in DNA Adenine always pairs with Thymine; Guanine always pairs with Cytosine Corp- body Covalent bond- chemical bond resulting from sharing of electrons between atoms Cyto- pertaining to the cell Cytokinesis- the division of cytoplasm in a dividing cell Deciduous- trees that lose their leaves but do not die Deoxyribose- the pentose sugar found in DNA (deoxyribonucleic acid) Di- two Ecology- the study of the interactions between living and nonliving factors in a particular area Endocytosis- the process by which liquids/substances are taken up by the cell Endo- within Enzyme- type of protein that usually serves as a catalyst (speeds up a chemical reaction) Epi- over or above Eukaryote- cell that contains organelles Exo- outside, out of Exocytosis- the process by which waste leaves the cell Extra- outside of Flagell- whip Gamete- mature sex cell, can be sperm or egg Gastr- stomach Glycogen- storage form of energy in animals Hetero- prefix meaning different Homo- prefix meaning same Hyper- prefix meaning above average Hypo- prefix meaning below average Intra- within Iso- prefix meaning same Ligand- any molecule that binds to the receptor site of another molecule Lipids- molecules that are lipids include: fats, oils, waxes, and steroids Lysis- process that involves breaking down or bursting apart Macro- prefix that indicates a large size Meiosis- the process of division of sex cells (sperm and egg) Meso- middle Micro- prefix that indicates a small size Mitosis- the process of division of somatic cells (all body cells that aren’t sex cells) Mono- one Monomer- small units that when put together make up polymers Morpho- shape or form Multi- many, more than one Myo- muscle Necro- death Neo -new Nucleic acid- monomer of DNA or RNA Nucleus- control center of the cell Organelles- collective term for all structures inside a eukaryotic cell Peri- around Phago- prefix that means to eat Photo- prefix that means light Pino- prefix that means to drink Poly- multiple or many Pseudo- fake or false Prokaryote- cell that does not contain organelles Protein- polymer consisting of amino acid monomers Semi- half Soma- body Sub- prefix that indicates a structure is below another structure Super or supra- above Sym or syn- root that indicates being together Trans- across Tri- three Troph- nourish Viscero- organ
