Summary list for 9.4 Reproduction in plants
- Flowering involves a change in gene expression in the shoot apex which is a response to the length of light and dark periods in many plants
- Outline details of the processes of pollination, fertilization and seed dispersal which are needed for success in plant reproduction.
- Most flowering plants use mutualistic relationships with pollinators in sexual
reproduction. - Methods used to induce short-day plants to flower out of season such as chrysanthemums, use long uninterrupted nights rather than short day
Skills
- Draw internal structure of seeds.
- Draw half-views of animal-pollinated flowers.
- Design of experiments to test hypotheses about factors affecting germination.

Drag and drop activities
Test your ability to construct biological explanations using the drag and drop questions below.
An investigation was carried out to determine whether red or blue wavelengths of visible light affect the rate of germination of Lactuca sativa (lettuce) seeds.
Drag and drop the correct word into the gap to outline the variables of an investigation into germination.
aerobic energy radicle humidity Age Number absorbed Independent intensity Temperature Volume light
variable:
Wavelength of .
Dependent variable:
Time in hours of the emergence of the on germination.
Controlled variables:
of seeds in each condition.
Light .
(affects enzyme activity).
of water (is by the seed).
Oxygen (for respiration).
of seeds (older seeds may be less viable).
Explanation: A variable must be able to be measured, the dependent variable is not germination but the time taken to germinate.
