Document Summary

Carboniferous the continents are starting to come together in pangea that will allow for the global diversi cation. End of the permian is the beginnings of one big land mass- pangea. Permian was one of the biggest mass extinctions to occur. Carboniferous is when we start to see vascular plants and they will lay down all the carbon and cold deposits. Huge trees of the carboniferous are represented today by miniatures of them. The huge trees of the carboniferous fell down and fossilized into the coal of today (?) Develop true leave (photosynthetic tissue that has transport and vascular tissue in it) No longer have to rely on symplastic transport we now have phloem and xylem. In their circular piece of chloroplast dna there is a section that has inverted and repeated. Ferns still only have dispersion of spores but they will improve the technique of doing it.
