rise of eukaryotes
rise of angiosperms
rise of chemoautotrophs and photoautotrophs
rise of bryophytes
rise of gymnosperms
rise of cyanobacteria
rise of multicellularity

Answer 1

Answer:

i)The eukaryotes developed at least 2.7 billion years ago, following some 1 to 1.5 billion years of prokaryotic evolution. ... Therefore, a very early event in evolution appears to have been the divergence of three lines of descent from a common ancestor, giving rise to present-day archaebacteria, eubacteria, and eukaryotes.

ii)Today, angiosperms represent nearly 90% of all extant plant species and dominate most of Earth's terrestrial ecosystems. ... In contrast, gymnosperms appeared well before angiosperms in the Devonian (∼380 Ma) and flourished in diversity during the Mesozoic (14, 32⇓–34).

iii)Phototrophic organisms capture light energy from the sun and convert it into chemical energy inside their cells. Chemotrophic organisms break down either organic or inorganic molecules to supply energy for the cell. ... Photoautotrophs are cells that capture light energy, and use carbon dioxide as their carbon source.

iv)In the bryophytes the gametophyte is dominant. Gametophytes are persistent and, from time to time, gives rise to sporophytes. Spores produced by the sporophyte germinate to produce more gametophytes, which may then give rise to more sprophytes and so on.
