Dispersal of seeds

Principle

For a seed plant, not only the production of numerous seeds, but also their widest possible dispersal, are of great importance fort he preservation of the species. Many plants have developed different mechanisms to ensure the dispersal of their seeds. The seeds of the pine tree or the spruce examined in this experiment get dispersed by the wind (anemochory).

Benefits

• Experiment is part of a complete solution set with a total of 44 experiments for botany, reproduction, soil, food and digestion, senses, physiology.

• With student worksheet, appropriate for all class levels.

• With detailed instructor information.

• Optimized for tight schedules, i.e. minimum preparation time required.

• Biology solution set specifically designed to include all required accessories.

Tasks

Examine where the seeds are situated in a pine-cone or a spruce-cone and determine which devices or actions serve their dispersal.
