Program of multiple-choice questions in plant physiology with feedback. To be used in a tutorial setting. Approximately five hours of teaching material.
Using simple demonstrations and time-lapse photography explains the principles underlying the structures of seedlings, shoots, herbaceous plants, trees and leaves. Using the microscope, examines how these...
Looks at the causes of flowering, examining factors such as day length and night length. Shows how this information is used by commercial growers of chrysanthemums. Also discusses crops such as celery where...
A review of our knowledge of how plants utilise sunlight, including the research that led to the 1988 Nobel Prize for chemistry. Plants produce oxygen when exposed to light, and produce starch. The green...
Looks at the simple patterns that underlie the myriad diversity of form in plants and flowers. Despite apparent complexity most leaf patterns and flowers are variations on three basic patterns, which are...
Two studies examine factors that regulate plant growth. Phototropism is the growth of a plant stem towards the light. The validity of the Cholodney-Went theory of phototropism is considered in the light of...
When does biology seem to outstrip simple physics? Ordinary air pressure can only raise a column of water up ten metres, but a giant redwood tree can raise it more than 100 metres. The film demonstrates how...
Shows the principles of plasmolysis: the movement of water from plant tissue after application of a hypertonic solution, the detachment of the living protoplast from the cell wall, the reversibility of...
