BI 115 - Laboratory for BI 110
Credit Hours: 1.5
The laboratory will include physical and biochemical characteristics of cells, tissues, structure of plants and animals, genetics and DNA analysis.
Fulfills SUNY General Education -- Natural Sciences.
Upon completion of the course, the student will be able to:
- 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 vs. 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.
