Notes on Introduction to cells According to the cell theory, living organisms are composed of cells Organisms consisting of only one cell carry out all functions of life in that cell Surface area to volume ratio is important in the limitation of cell size Multicellular organisms have properties that emerge from the interaction of their cellular components Specialized tissues can develop by cell differentiation in multicellular organisms

DNA differs from RNA in the number of strands present, the base composition, and the type of pentose The nucleic acids DNA and RNA are polymers of nucleotides DNA is a double helix made of two antiparallel strands of nucleotides linked by hydrogen bonding between complementary base pairs And activities such as: Drawing simple diagrams of the structure of single nucleotides of DNA and RNA, using circles, pentagons, and rectangles to represent phosphates, pentoses and bases

Respiration powerpoint: Cell respiration is the controlled release of energy from organic compounds to produce ATP ATP from cell respiration is immediately available as a source of energy in the cell Anaerobic cell respiration gives a small yield of ATP from glucose Aerobic cell respiration requires oxygen and gives a large yield of ATP from glucose
