1Describe the Characteristics of Plants
Photosynthetic Autotrophs-Plants self-feed by converting solar energy to stored Chemical Energy through Photo Synthesis
Multicellular-Makes it distinguishable from other photosynthetic Autotrophs
Terrestrial-Most plants evolved from terrestrial ancestors
Clade-They are Monophyletic
2Name the Synapomorphic trait of Plants
Generations alternate
Spores are produced in Sporangia (Large Numbers)
Multicellular Gametangia-Produce many gametes
Apical Meristems-Self Renewing, give rise to all plant parts
3What is a Gametophyte
A multicullular haploid stage
Produces Haploid Gametes by Mitosis
4What is a Sporophyte
A multicellular Diploid Stage
Produces haploid spores by meiosis
5What happens in the life cycle of a plant?
The organism alternates between a gametophyte and a sporophyte
6What are plants thought to have evolved from?
Chlorophytes
7How long were plants on land?
475 million years
8Plant evolution was made possible through who?
Animals made the adaption to life on land
9List the abilities that came with living on land
-Resistance to Water Loss
-Support of the plant body which is made out of cellulose and lignin
-Transport Water and Energy through the vascular tissue
-Growth
