Recently, scientists have discovered a lost world that could unravel the story of the evolution of life on the planet.
About Protosterol Biota:
- It is the microscopic organism, belongs to the family of organisms called eukaryotes.
- These are discovered inside a rock at the bottom of the ocean near what is now the Northern Territory in Australia.
- They have a complex structure combining mitochondria.
What are eukaryotes?
- These cells possess a clearly defined nucleus.
- These cell have a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.
- These cells also contain organelles, including mitochondria (cellular energy exchangers), a Golgi apparatus (secretory device), an endoplasmic reticulum (a canal-like system of membranes within the cell), and lysosomes (digestive apparatus within many cell types).
- These are thought to have evolved between about 1.7 billion and 1.9 billion years ago.
Q1) What are Prokaryotes?
Prokaryotes are a group of organisms that constitute one of the two major domains of life, the other being eukaryotes. They are single-celled organisms that lack a distinct nucleus and other membrane-bound organelles. Prokaryotes include bacteria and archaea.
