BI 115 - Laboratory for BI 110

• microscope: explain proper use and care of the compound microscope; including naming the parts, noting the functions and determining the diameter of field of a microscope;
• molecular models: construct molecular models and identify major biological molecules and functional groups of organic compounds;
• plant and animal cells: use models of cells and organelles to compare the anatomy of plant and animal cells;
• plant cells and tissues: examine and identify the major anatomical features of a plant root, leaf and stem; describe plant organelles (allow students an opportunity to gain first hand observations of these by making slides of an onion, elodea leaf, geranium leaf epithelium, and other living plant cells);
• animal cells and tissues: use slides of animal cells to study organelles in animal cells; identify twelve major tissues found in the body (noting the location of each) and make drawings labeling major parts of each tissue;
• physical aspects of life: perform experiments involving the processes of osmosis, diffusion and dialysis; graph the results of these experiments and draw conclusions;
• chemical aspects of life: perform and interpret results of chemical tests on biological molecules; explain the mode of action of the tests on chemical compounds;
• enzymes/cell respiration: study the effect of temperature, pH and concentration on enzyme activity;
• mitosis: differentiate plant versus animal cells during the various phases of mitosis; 
• Mendelian genetics and corn: explain Mendelian laws of genetics including Mendelian ratios, outcomes of monohybrid and dihybrid crosses; be able to solve genetic problems and perform a Punnett square test and interpret results from data accumulated; and 
• genetic fingerprinting: explain and apply DNA analysis via gel electrophoresis.
