Question

70.Explain how the phylogeny of Eukaryotes represents a polytomy between the supergroups. 71.Explain the relationship between Horizontal Gene Transfer, the Web of Life and plastids+mitochondria. 72.Explain why protist is a non-monophyletic term. Explain why algae is a non- monophyletic term. 73.What lineage underwent Tertiary endosymbiosis? 74.What are red tides? 75.What is a cause of bioluminescence in California? 76.What is diatomaceous earth, what supergroup is this related to? 77.Are most organisms in the Eukaryote super groups unicellular or multicellular? 78. Explain the difference between primary and secondary endosymbiosis. 79.How are chloroplasts between red algae and green algae+land plants different? How is this an example of homoplasy?

Answer 1

70. There are 4 supergroups for Eukaryotes:-

i. Archaeplastida

ii. Unikonta

iii. Chromalveolata

iv. Excavata

Eukaryotic cells can meander without anyone else, in some cases framing crowds of free-living pico-sized life forms that twist in seas. They can be parasites or symbionts, or meet up by the billions in firmly stuffed, exceptionally managed multicellular life forms.

Perceiving this incredible decent variety and pushed by a craving to build up request, scientists have since a long time ago endeavored to gather a worldwide eukaryotic tree of life. A completely settled phylogenetic tree including all life forms isn't just a definitive objective of systematics, it would likewise give the establishment to construe the obtaining and evolution of endless characters through the historical backdrop of long-dead species.
