Question

Protobionts gave rise to:

• A. Primitive prokaryotes
• B. Primitive eukaryotes
• C. Primitive mesokaryotes
• D. All the above

Answer 1

The correct option is A Primitive prokaryotes

Prokaryotes are recognized to be the primitive living organisms of the Earth as they are the simplest forms of life. The shape of a prokaryotic cell is not as complicated as eukaryotic cells as they have first cell organelles. Prokaryotes dominated evolutionary history from 3.5 to 2.0 billion years ago. The early protobionts must have used molecules present in the primitive soup for their growth and replication. Eventually, organisms that could produce all their needed compounds from molecules in their environment, replaced these protobionts.
So, the correct option is A.
