Modes of seed dispersal in plant communities __null__

Students can compare different seeds successively with a magnifying glass or with the naked eye and deduce the preferred mode of dissemination.

About a dozen species, randomly arranged on the slide, illustrate 3 modes of transport:
- By the wind: birch, maple, elm, ash, dandelion, and clematis
- By animal fur: hound's-tongue and carrot
- By birds (through the digestive system): nightshade, privet, currant
