Document Summary

From seed to tree: seed to germination, seed dispersal, seed anatomy, germination, from primary to secondary plant body, body plans of major angiosperms groups, seed dispersal. Without seed dispersal adaptations, most seeds are deposited close to mother plant. Dandelion: whenever there is even the slightest wind, the seeds just do(cid:374)(cid:859)t fall like ro(cid:272)ks to the bottom. Sea beans, coconut have hard/ sturdy seeds. Coconut one single embryo inside is protected by a huge mass which can withstand to be exposed to salty ocean water in many months; eventually deposited at a suitable shore where the embryo starts germinating. Burdock largest external hitchhikers; found in ontario. Animals eat the seeds and will be pooped out. Seed will be encapsulated with feces that contains fertilizer. Typically, when the seeds are ready the color starts to contrast the green background so that animals can learn how to find them.
