Overview

"Introduction to Cell Biology" offers first-year undergraduates a foundational exploration of cell structure, function, and regulation. The course covers eukaryotic and prokaryotic cells, emphasizing organelle roles in metabolism, transport, and signalling. Students delve into cellular processes like the cell cycle, respiration, and protein synthesis, as well as intercellular communication mechanisms. The module highlights cellular diversity, differentiation, and their contributions to tissue and organ systems. Wider biomedical relevance is explored, linking cell biology to disease understanding and treatment. Students will explore the diversity of microbial life, including bacteria, viruses, and fungi, and will examine their roles in health, disease, and the environment. Through this module, students will develop a foundational understanding of microbial growth, metabolism, genetics, and their interactions with host organisms, as well as gain insights into the importance of microbiology in medical and applied sciences.

Assessment Strategy

Examinations for this module will be conducted on campus in an invigilated environment. These exams will follow a closed-book format, meaning that no external materials, including notes, textbooks, or online resources, will be permitted during the examination. This approach is designed to assess your understanding and application of the module content under standardised and fair conditions.

Threshold (D- to D+) A threshold student demonstrates basic knowledge of the essential facts and key concepts presented in the module. The work covers the module material only partially, and there may be gaps or inaccuracies. Arguments are present but may be underdeveloped, lack depth, or contain limited support. Examples may be sparse or only loosely connected to the points being made. The work lacks detailed analysis, critical thinking, and supporting evidence. Overall, performance in this range shows minimal competence with the module content, reflecting a basic but incomplete understanding. Satisfactory (C- to C+) A student achieving a satisfactory grade demonstrates a reasonable understanding of the essential facts and key concepts introduced in the module. The work covers the core material but may lack depth and may exhibit occasional inaccuracies or gaps in knowledge. Arguments are generally present but may be underdeveloped or lack clarity and support. Examples, where included, are relevant but may not be comprehensive or fully aligned with the argument. There is limited evidence of critical thinking, but a basic grasp of the material is evident. Performance at this level indicates an acceptable engagement with module content, but there is room for improvement in analysis, argumentation, and support. Good (B- to B+) A good student demonstrates a thorough factual knowledge across all aspects of the module and can provide relevant examples where appropriate. The work shows a logical and well-structured argument supported by module materials. It reflects a solid understanding of the content, with evidence of engagement and some critical thinking. Examples and evidence are used effectively to support the argument. This performance level indicates a strong grasp of the material, with clear, coherent expression and detailed understanding of core concepts. Excellent (A- to A) An excellent student demonstrates a thorough factual knowledge across all aspects of the module and can provide detailed examples that enhance understanding, supported by additional reading and knowledge drawn from other modules or sources. The work is characterised by a logical, cohesive, and well-supported argument that reflects a high level of understanding. Critical thinking is evident throughout, and there is clear evidence of engagement with wider reading, particularly for A+ and A grades. Work at this level demonstrates comprehensive insight, originality, and an ability to synthesise and apply knowledge effectively across various contexts.
