How did protists evolve?

Scientists assume that the very first protists developed from prokaryotes Proof shows that eukaryotic organelles such as mitochondria and chloroplasts stemmed as prokaryotes that lived inside other, bigger prokaryotic cells. This hypothesis is called the endosymbiotic hypothesis or the Theory of Endosymbiosis.

How did protists develop from prokaryotes?

The protists have actually developed from prokaryotes throughout which the nucleus divided by means of mitosis, histones were connected with the DNA, an endomembrane system and a cytoskeleton were formed, and they established the capability to make flagella or cilia for motion from one location to another. 2.

In organisms that replicate sexually, when a sperm fertilizes an egg cell, the outcome is a cell called the zygote, which consists of DNA of the 2 moms and dads. In plants, animals, and some protists, the zygote will start to divide by mitosis to produce a multicellular organism. The outcome of this procedure is an embryo.
