Document Summary

Explained what we are gonna learn, and went through the syllabus really quick. Today and the following week we are going to look at: basal tree of life, bryophytes, lycophytes, ferns, gymnosperms, angiosperms most plants fall under this category. Life on earth originated about 1000 million years after earth originated; bacteria evolved and earth was only inhabited by prokaryotes. In the proterozoic era, green algae, the ancestor to plants, evolved. Lose and uptake of water along whole surface; the surface is permeable. They dont water just through roots, but from entire surface. Since plants only grow using water, therefore, bryophytes are found in very wet, moist climates. Adapted to survive total desiccation. if it loses all its water, it hibernates and goes into a. Resting mode and when they get water back in the system they come back to life and resume photosynthesis etc: no vascular system. Vascular system is what is responsible for transporting foods and sugar.
