Key learning points

1. Seeds are dispersed by different mechanisms to increase the chance of survival.
2. Seeds are adapted to match the mechanism for dispersal; e.g. wind dispersed are light with a large surface area.
3. Variables are factors that affect the process being investigated, the dependant variable is distance the seed travels.
4. Practical investigation of how far model seeds disperse with changes to their template.
5. Repeat measurements for each value to identify anomalous results and calculate a mean.

Keywords

• Seed dispersal - Mechanism by which seeds are transported away from the parent plant.

• Adaptations - Features of living organisms that help them survive in their environment.

• Variable - Factor in a scientific investigation which may have an effect on the process being studied.

• Repeats - Measurements of the same value allows anomalous results to be identified.

• Mean - A measure of average where all values are added together and divided by the number of repeat measurements that have been taken.
