Study about plant physiology and its implications for crops; post harvest management and more. This course explains the principles and processes of plant physiology and their practical applications. It builds on prior studies in Botany A, plant physiology or other courses from the careerline range in Agriculture, Horticulture or Science.
Best studied with Introduction to Botany.
- Investigate the physiology of growth development and flowering.
- Examine the nature of phytochrome and its effect on flowering in the phytochrome reaction.
- Examine the photoperiodic responses of flowering plants to differing dark and light periods.
- Examine the effect of temperature on the onset of flowering and flower development.
- Understand and describe the causes of dormancy in seeds and plants and describe the methods of breaking dormancy.
- Understand plant associations and competition and their effects on quality and marketable yield.
- Explain the process of respiration in plant cells and its effect on post-harvest storage and transportation of crops.
- Describe physiological processes in post-harvest crops in relation to the storage conditions.
- Investigate the effect on plants of endogenous and synthetic growth regulators.
- Understand risk assessments relevant to plant growth manipulation.

When you have completed the lessons of your Certificate course, you will be given the option of taking the optional exam. It's okay if you don't want the exam, we still issue your Careerline Certificate. For Advanced Certificates however, the exam is compulsory (per module) and are included in the course fee.
Bachelor of Science (Zoology) (Hons), M.Phil. PhD (UTS) current.
I am currently doing my PhD in Environmental Science at the University of Technology Sydney. My research is centered around the effects of climate change on the hatchling velvet gecko population in Australia. This involves collecting wild gravid geckos and incubating their eggs under laboratory conditions. Through exposure to a variety of incubation temperature treatments, I have operationalized my investigation which aims to determine the effect of higher temperatures on hatchling geckos. I am currently in stage 3 of research, which comprises writing a thesis and developing manuscripts for publishing. Prior to my present endeavors within the scientific field, I have also successfully completed a B.Sc. degree, majoring in Zoology, (specialised field: Wildlife Management) with first-class honors and an M.Phil. Degree in Life Sciences. My passion has always been teaching and thus I have worked for seven years as a lecturer at various universities. I love helping students with their own studies.

Frequently Asked Questions
Can I pay in installments?
Yes! We offer great payment plans, however full payment up front is the cheapest. You can choose the best payment plan for you from the course page, or call us on 07 55368782 to talk to one of our course consultants for a custom plan.
Can I study from anywhere in the world?
We have many international students. Careerline's range of courses are suitable for any one, anywhere in the world.
Do I get a discount if I enroll in a second course?
Yes. You may claim a 5% fee discount when you enroll in a second course, and a further 10% off a three-course package.
Do I have to sit an Exam?
No. If you are enrolled in a Certificate course (100hrs), the exam is optional. You will be issued with a certificate which proves that you are competent in all units, if you choose not to sit the exam.
Do you have set start dates?
There are no set start dates, you may start at any time. Our courses are all self-paced. As our home page says, ‘Courses for Anyone, Anywhere, Anytime’. ‘Anytime’ includes the start time of your choice. However, we do encourage our students to submit assignments on a regular basis. Wherever possible, we suggest developing a study routine.
