Module Description: The main aims of this module are to deliver the basic concepts, theory and practical techniques of biological and chemical sciences, which are relevant to an agricultural scince based programme. Students will receive training in basic laboratory skills used in Biology,Chemistry and Biochemistry.
 
Module Learning Outcome
On successful completion of this module the learner will be able to:
# Module Learning Outcome Description
MLO1 Appraise the basic concepts of biology and chemistry, atoms and elements formation, their physical characteristics, and molecular basis of life.
MLO2 Explain the fundamental principles of biological systems from the molecular and cellular aspect of an organisms
MLO3 Interpret the structure of organic molecules and biomolecules and practice nomenclature and drawing of these structures
MLO4 Critique the differences between prokaryotic and eukaryotic cells, and the main principles of genetics and inheritance pattern
MLO5 Explain the interaction between cells and their environments and the structures within the cells which are involved in these interactions
MLO6 Operate Good Laboratory Practice (GLP) for biological and chemical analyses of laboratory samples.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named DkIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Module Indicative Content
Biology:
Cell structure and functions of macromolecules; kinetic and potential energy; chemistry of life and molecules of life, structure of large biological molecules; prokaryotic and eukaryotic cells; basic plant and animal cell structures, cellular organelles; principles of genetics, mitosis and meiosis, transcription and translation, inheritance pattern; proteins synthesis, enzymes, molecules of energy; photosynthesis and cellular respiration (aerobic, anaerobic and fermentation); plant physiology (function and reproduction); interaction between cells and their environment and structures within the cells which are involved in these interactions; diversity of life and evolution, introduction to ecology.
Chemistry:
Periodic table of elements (groups, periods, family), atomic structure, atoms and elements, atomic and ionic sizes; chemical bonding of elements (ionic and covalent); elements and their physical characteristics; physical mixture versus chemical compounds; expression of chemical reactions; balancing chemical equations (atoms, moles, density, chemical prefixes, international system of units (SI Units), molarity, PPM and % solutions); scientific measurements (precision, accuracy, uncertainly in measurements, significant figures and rounding); acids and base reactions, strong and weak acids, pH of strong and weak acids/bases; pH (pH definition, scale and calculation, buffering capacity, soil/natural waters pH, soil pH requirements); titration (acid-based titration, precipitation titration, redox titration); redox reactions; indicators and buffer solutions; chemistry in aqueous solutions; factors affecting chemical reaction (physical state, concentration, temperature, catalytic influences, and pressure) classification of organic compounds based on functional groups, structure, bonding and physical properties (boiling points and solubility); different types of biomolecules (amino acids, proteins, carbohydrates, fats, enzymes and vitamins).
Practicals:
During the practical sessions students will learn fundamental Good Laboratory Practices used in Biology, Chemistry, and Biochemistry, including microscopy, pipetting techniques and making up solution testing accuracy and repeatability, making up solutions, concentration calculation, titration, DNA extraction and analysis, enzyme activity, protein extraction and analysis, determination of glucose concentrations. These practicals will be applied to agri-environmental science and food science.
