Plants

Description - summary of the module content

Module description

This module aims to introduce you to the important concepts, techniques and applications of modern plant science, and to explore the impact of plants on the biosphere, agriculture and society.

In order to take BIO1338 you should normally have an A Level (or equivalent) in Biology.

Module aims - intentions of the module

As primary producers, plants are fundamental to life on Earth. Stage 1 “Plants” aims to provide you with a fundamental understanding of important topics in plant science including the evolution of plant cells, the basic morphology of different plant groups, the physical constraints that influence the diversity of plant forms, the environmental and endogenous regulators of plant growth and plant reproduction. The importance of light, CO2 and water for plant life, evolution and morphology will be explored against the background of environmental change. Light sensing, photosynthesis, and the strategies that plants employ to maximise carbon capture and water use efficiency will be explored. Using pertinent case-studies and research, we will investigate the molecular and physiological basis for human exploitation of the plant world through agriculture, plant breeding, GM technology and Synthetic Biology. Lectures will be illustrated with hands-on materials when possible and supplemented by practical classes in which you will perform experiments to expand and integrate your theoretical knowledge, further your awareness of the scientific method and take part in self-directed or/and guided discussion of results to increase your understanding of the topics under investigation. You are expected to supplement knowledge gained from lectures by self-directed reading from textbooks and literature appropriate to the level (e.g. reviews and selected primary sources).

Syllabus plan

Syllabus plan

The syllabus will include lectures and practical classes that address the following topics:

• Plant evolution – physical constraints and selective pressures – interaction with other organisms.
• Plant cell structures and continuous embryogenesis – vacuole; cell wall; chloroplasts; meristems
• Diversity of plant structures from a basic pattern – root/shoot polarity and vascular plant cell types.
• Plant anatomy and branching.
• Light – photoreceptors, the chloroplast and photosynthesis (C3, C4 and Crassulacean Acid Metabolism).
• Plant metabolism and secondary products.
• Water relations.
• Plant growth regulators (with practical class)
• Alternation of generations and reproductive strategies, including pollination syndromes.
• Forward and reverse genetics.
• Domestication, Quantitative Trait Loci (QTL), plant breeding and agriculture.
• Genetic modification (GM) and Plant Synthetic Biology.

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The practical assessment is not deferrable because of its practical nature. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination. The mark given for a re-assessment taken as a result of referral will count for 100% of the final mark and will be capped at 40%.
