AGRI06004 2019 Plant Science
This module describes how plants grow and reproduce and how they provide a source of food for animals and man. It describes the structures of plants that provide for growth, photosynthesis and reproduction. It explains the factors that affect plant growth in terms of environmental conditions and how plants are affected by disease caused by fungi and viruses. It describes the classification and features of plants of agricultural importance including weeds.
On completion of this module the learner will/should be able to;
Explain how plants (including higher and lower plants, fungi and algae) are classified and the main families of plants of agricultural importance including weeds.
Compare the morphological differences between monocot and dicots and give examples of plants belonging to each group
Outline plant cellular structure and functions
Explain the mechanisms and factors affecting plant growth and processes, such as plant hormones, photosynthesis, respiration, water and nutrient uptake, transpiration and disease.
Explain the process of plant propagation, pollination and fertilisation, seed dispersal and seed germination.
Teaching and Learning Strategies
This module will be delivered full-time.This will include lectures and laboratory practicals augmented by independent learning and directed learning. This approach is expected to address student learning needs. Moodle will be used as a repository of educational resources and as a means of assessment (e.g. quizzes, uploading assignments and journals).
Module Assessment Strategies
The students will be assessed by 100% continuous assessment (50% theory and 50% practical). Theory assessment includes short answer questions, MCQs and assignments. Practicals will be assessed by laboratory reports, maintenance of a laboratory notebook and MCQ's/short answer questions.
Repeat Continuous Assessment and/or Final Exam.
Theory - may change at the discretion of the lecturer to meet the learning outcomes
Composition of plant cells and function of plant organelles
Cellular anatomy of roots, vascular tissues, leaves, flowers and seeds
Modifications of root and stems in terms of vegetative propagation and storage of reserve food material
Plant growth stages of grasses
cereals, root crop, vegetable and fruit
Sexual reproduction, pollination, fruit and seed development, seed dispersal and germination
Differences between annual, biennial and perennial plants
Plant biochemistry, carbohydrates, hexoses and pentoses, mono-, di- and polysaccharides. Nucleic acids and protein synthesis
Metabolic pathways in relation to respiration and photosynthesis (C3 and C4 carbon fixation)
Environmental factors affecting plant growth
Transport of water, nutrient and pesticides in plants by osmosis, active transport, transpiration and translocation
Classification of plants (algae, mosses, liverworts, horsetails, and ferns), conifer and angiosperms, differences between monocots and dicots
Use of keys for identifying plants. Features of plant families of agricultural significance
Role of plant breeding/genetics in producing new varieties to enhance crop yield, quality, tolerance to environmental factors, and resistance to pests and disease
Role of bacteria and fungi in the biodegradation of organic matter. Carbon, nitrogen, phosphorus and sulphur cycles
Practicals - a selection of the following will be undertaken
Main diagnostic features for for plant, algae and fungi identification - including use of dichotomous keys
Morphological features of plant families of agricultural significance
Cellular anatomy of roots, vascular tissues, leaves, flowers and seeds
Environmental factors affecting plant growth (e.g. light, temperature, water, pH, oxygen, carbon dioxide and nutrient requirements)
Characteristics of fungi and selected plant pathogens and Kock’s postulates

Required & Recommended Book List
2018-03 Plant Physiology and Development
ISBN 1605357456 ISBN-13 9781605357454
Published by Sinauer Associates, an imprint of Oxford University Press. Throughout its twenty-two year history, the authors of Plant Physiology and Development have continually updated the book to incorporate the latest advances in plant biology and implement pedagogical improvements requested by adopters. This has made Plant Physiology and Development the most authoritative, comprehensive, and widely-used upper-division plant biology textbook.
2012-04-30 Functional Biology of Plants Wiley-Blackwell
ISBN 0470699396 ISBN-13 9780470699393
Functional Biology of Plants provides students and researchers with a clearly written, well structured whole plant physiology text. Early in the text, it provides essential information on molecular and cellular processes so that the reader can understand how they are integrated into the development and function of the plant at whole-plant level. Thus, this beautifully illustrated book, presents a modern, applied integration of whole plant and molecular approaches to the study of plants.
It is divided into four parts: Part 1: Genes and Cells, looks at the origins of plants, cell structure, biochemical processes and genes and development. Part 2: The Functioning Plant, describes the structure and function of roots, stems, leaves, flowers and seed and fruit development. Part 3: Interactions and Adaptations, examines environmental and biotic stresses and how plants adapt and acclimatise to these conditions. Part 4: Future Directions, illustrates the great importance of plant research by looking at some well chosen, topical examples such as GM crops, biomass and bio-fuels, loss of plant biodiversity and the question of how to feed the planet.
Throughout the book there are text boxes to illustrate particular aspects of how humans make use of plants, and a comprehensive glossary proves invaluable to those coming to the subject from other areas of life science.
2005-01-10 Plant Pathology, Fifth Edition Academic Press
ISBN 0120445654 ISBN-13 9780120445653
This fifth edition of the classic textbook in plant pathology outlines how to recognize, treat, and prevent plant diseases. It provides extensive coverage of abiotic, fungal, viral, bacterial, nematode and other plant diseases and their associated epidemiology. It also covers the genetics of resistance and modern management on plant disease.
Plant Pathology, 5th Edition, is the most comprehensive resource and textbook that professionals, faculty and students can consult for well-organized, essential information. This thoroughly revised edition is 45% larger, covering new discoveries and developments in plant pathology and enhanced by hundreds of new color photographs and illustrations.
* The latest information on molecular techniques and biological control in plant diseases
