What complex structures used for locomotion evolved in protists?

Flagella, Cilia and Cytoplasmic Streaming. Cilia are small hairlike structures that protists use to "crawl". A flagella is a long tail that pushes and propels the protist forward, also used by sperm cells. Cytoplasmic Streaming is used by the amoeba to "ooze" its way to places.

Which evolved first - organisms with complex body structures or those with simple body structures?
Complex organisms evolved from simple organisms, so simple organisms evolved first.
How do scientist think the first protists evolved?
endosymbiosis.
What evidence exists to support the idea that poriferans evolved from protists?
Shoko
Plant and animal cells have certain structures in common they also have certain structures that are different Why?
They both evolved from the same multicellular organisms, so they have structures in common. But they did that a long time ago, so they have evolved different structures.
Are protists monophyletic polyphyletic or paraphyletic?
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.

What are similar structures that evolved independently called?
Similar structures that have evolved independently are called homologous structures. An example would be the wings of a bird and the wings of an insect.
Similar structures that evolved independently?
homologous structures

Have protists evolved from earlier life forms?
It is now thought that, although green plants probably evolved from the green algae and animals from some other early forms, most modern protists have followed independent evolutionary lines. So, ******No****** they have evolved individually!
What kingdoms came from protists?
protista is a kngdom. hope this answers your question
What group of protists did the first plants evolve from?
Scientists thing protists evolved from archaea, which are simply single celled organisms.
Plant and animal cells have certain structures in common they also have certain structures that are different Why?
They both evolved from the same multicellular organisms, so they have structures in common. But they did that a long time ago, so they have evolved different structures.
What are similar structures that evolve independently?
Similar structures that evolved independently are called analogous structures, or analogies.

Do gliding animals that have evolved structures slow their fall?
Gliding animals have indeed evolved structures that slow their fall. Their wings act as a parachute slowing their fall to the ground.
