Selected Evolution takes place when one member of a specie has an property that is genetical and gives him an higher chance of surviving. This gives him an higher chance he wil get children, and his children will also have an higher chance of surviving.
You get these things in like class 1 of the highschool. Feel ashamed.
Yew , unicellular organisms are more primitive as compared to multicellular organisms .
Single cell organisms still exist because populations evolve, rather than entire species. Additionally, if an organism is fit in it's environment, it is not pressured into evolving.
Blue green algae are procaryo and mostly unicellular and form a source of food for other organisms. i.e, why blue green algae are called primitive organisms.
These were primitive anarobic organisms like becteria

It evolved from Primitive transportation.

No
If they do not evolve, they may eventually die out.
all of the organisms can evolve.

Darwin said that organisms evolve through the process of natural selection.
The mechanism for evolution that was proposed by Jean Baptiste Lamarck was that organisms began life as primitive forms but adapted to their environment and became more complex forms. He also claimed that as time progressed, new primitive organisms were also occurring, so that they may evolve in the future.
