Document Summary

All species on earth and grouped into three kingdoms. Focusing on plants which evolved from algae*** At first no life present (the lines on slide escalating to the end of the time line show boom in organism appearance. 600 million years ago first life form evolved ; bacteria. Ancestors of all plants , starter on phylogeny chart( bottom, basis) Later on in lecture talks about comparison of species on phylogeny chart( compares population) Cuticle is waxy layer on top of the epidermis. During lecture talk about where it is based on diagrams on slide. ( slide 20) Loss and up take of water along whole surface. Ex: as soon as the sun hits it, they will dry up very quickly. This causes bryophytes to live in very most areas. Ex: ravine and places where the sun will most likely not hit. If you water a totally dead bryophyte , it can come back to life.
