The seed, germination, angiosperms and gymnosperms.

Do you know how a seed germinates?

Look at the video:




And, do you know what is a "time lapse"? It is a photography technique that consists in taking pictures of process that takes slow in the time and then make a video showing all together.

We have and example of a time lapse here, we are going to see how a bean germinates. As you know (remember the beans that we have attached to the window, in class), this proces takes long time but thanks to the time lapse we can watch it in a short time.
This one is by Neil Bromhall.

Enjoy it!




And finally, this is an old video but it explain perfectly well the diferences between gymnosperms and angiosperms.
