Learning Outcomes

Subject-specific Knowledge:

By the end of this module each student should be able to: Describe the composition and dynamic properties of cell membranes.
Explain how the various components of the cytoskeleton are organised and how they contribute to cell shape and movement.
Describe the basic composition of the extracellular matrix.
Integrate structural information on the various components of the living cell with its basic needs to move, divide and survive.

Subject-specific Skills:

Key Skills:

Extract, compile and review relevant scientific information from various sources and evaluate them critically.
Interpret and critically analyse sample experimental data and present the results effectively.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

Teaching and learning in this component is primarily through the means of lectures.
Skills will be acquired through the manipulation and presentation of data.
Knowledge will be formally assessed through the use of MCQs and summatively by a written examination.
Interpretation of data will be assessed by means of unseen data handling paper.
Understanding will be assessed by means of a written examination.
