Dr. Lynn Margolis proposed that some organelles may at one point have been free living (i.e. mitochondria) and found it more beneficial to be within a larger cell for their survival. The mitochondria would find protection and a supply of the nutrients they need while the larger cell would now have a source of energy, thus improving both.

Which is the best criteria to use when classifying cells as either eukaryotes or prokaryotes?
sizediet
What does the endo part of endosymbiosis refer to?
The prefix endo- means within. Endosymbiosis means that two organisms live together and both befit. One lives within the other. A good example is the millions of bacteria that live in your intestinal tract.
What is an organism that can survive with or without oxygen?
Facultative anaerobes can survive without oxygen but will use oxygen if it is present.
How do you use the word survive in a sentence?
You must need life jacket in order to survive on a boat or ship.
What are two other words for survive?
One synonym for survive would be prevail. You could also use the word endure.
What structures are used for motility in both eukaryotes and prokaryotes?
prokaryotes use flagella-eukaryotes use flagella and cilia
How did the early Romans use their surroundings to survive?
they ate the icecream made by the chinese
How did early humans use their early environment to survive in the old stone age?
they moved from place to place according to the weather
What process do eukaryotes reproduce asexually?
Eukaryotic cells (eukaryotes) use mitosis to reproduce asexually.
How do eukaryotes obtain energy and nutrients?
they use the process hemolophotic which means they eat anything and take the nutrients out of what they need to survive. for example they may eat part of a leaf to get water.
Protein synthesis in eukaryotes is similar to the process in prokaryotes in that both eukaryotes and prokaryotes?
use codons to determine polypeptide sequences
What kind of organisms use transcription factors?
Eukaryotes
What do flagellates use their flagella for?
Flagellates, unicellular eukaryotes, use their flagella for transportation.
How did the early people use their surroundings to help themselves survive?
Early humans became smarter, taller, faster, and better with tools.

What is multicellular eukaryotes that live on land and their own food use photosynthesis?
Plants. They live on land. Are multicellular. And use Photosynthesis
True or false prokaryotic cells are not effecient?
You'd have to define your conditions for "efficiency". While in general prokaryotes are simpler than eukaryotes, they obviously have their own advantages because both have become very successful over the course of evolution. Prokaryotes can be more efficient than eukaryotes in protein translation, for example, as the use of operons and polycistrons allows for efficiency. But eukaryotic cells have a lot of other advantages. In terms of energy production, eukaryotic cells may contain several mitochondria to generate ATP much faster than a prokaryote could on its own. After all, according to the endosymbiosis theory, mitochondria and chloroplasts have their origins as individual prokaryotes themselves.
