About this Course

Learn PLANT PHYSIOLOGY AND TAXONOMY with expert tutor support

You will learn the essential plant physiology and taxonomy.  This course will give you a sound introduction to plant morphology and anatomy; in agriculture, horticulture, environmental or plant science. Base knowledge for careers in teaching, pharmaceuticals or for those seeking a pathway to undergraduate plant specialist courses.

Though it is a stand alone course, in order to fully take advantage of this knowledge pathway, the Careerline course; ‘Botany II’ should be studied next.

Course Aims:

  • Understand the relationship between the scientific principles of this unit and horticultural practices
  • Demonstrate a knowledge of the Plant Kingdom and understanding of the taxonomic hierarchy
  • Identify and describe the different types of plant cells and tissues, their structure and function
  • Determine the role and function of specific vegetative parts of the plant
  • Determine the role and function of the reproductive parts of the plant
  • Demonstrate an understanding of the role and function of the seed in the life cycle of the plant
  • Explain the mechanism and the role of photosynthesis in the metabolism of plants and relate to plant growth in controlled environments
  • Explain the mechanism and the role of respiration in the metabolism of plants
  • Demonstrate an understanding of the role of water in the plant
  • Review the movement of water, solutes and assimilates through the plant
  • Understand the effects of tropisms and other plant movements on growth and development
