What similarities do mitochondria and chloroplasts share?
Mitochondria and chloroplasts have their own genetic informations, which is one of the reasons why people believe that mitochondria and chloroplasts have originated as a bacteria that started mutualism with an early eukaryote. This relationship is known as the endosymbiotic theory.
What is the endosymbiotic hypothesis of the origin of the eukaryotic cell?
The theory is that the original Eukaryotic cell came about by the consumption of a Prokaryotic cell by another Prokayotic cell. This smaller cell was incorporated into the processes of the other - thus forming a symbiosis. This theory is supported by the fact that chloroplasts and mitochondria have their own DNA (separate from the nucleus).
Why do scientists believe that mitochondria may have evolved from bacteria?
Scientists believe that mitochondria may have evolved from bacteria because they have their own DNA, replicate independently within cells, and have similar characteristics to certain types of bacteria. Additionally, the endosymbiotic theory suggests that mitochondria were once free-living bacteria that were engulfed by early eukaryotic cells and formed a symbiotic relationship.
Which came first, animals or plants?
Plants came first before animals.
Which came first, plants or animals?
Plants came first before animals.
Where do we think mitochondria and chloroplasts came from?
They are thought to evolved from bacteria. Symbiotic living have turned them into organelles
What did Dr. Lynn Margulis suggest about mitochondria and chloroplasts?
They were cells before and then they came together with a cell and then they became mutually dependent.
How many times is chloroplast larger than mitochondria?
This is a relatively complicated question as the exact origins of mitochondria and how they came to be included in eukaryotic cells is still under investigation and therefore open to debate.Everyone seems to agree though, that they originally come from bacterium and that they were assimilated into eukaryotic cells either because they were useful or through some form of symbiosis.As mitochondria are common to both plant and animal cells it could therefore be argued that they shared a common ancestor at some point in evolution.The inclusion of the chloroplast came later, and a separate line of mitochondrial and chloroplast carrying cells evolved - eventually becoming plants. The line without the chloroplast becoming animals.
What characteristics does chloroplasts and mitochondria share?
1 Chloroplast and mitochondria are double membrane bounded 2 They both came into existing by the process of endocytosis of bacteria 3 They both have their own nucleus In fact both these have more things in common.You can study them by viewing others sites on web

What 2 organelles were once free?
Mitochondria and chloroplasts used to be free-living. They used to be prokaryotes, but they got enveloped by other prokaryotes and their membrane became a double membrane because the first one stayed and the second one came from it being enveloped. Their DNA is also similar to prokaryote DNA. Their original cell membrane is also similar to a prokaryote's cell membrane.
Where are chloroplasts believed to have come from?
There is a theory that chloroplasts and mitochondrias were once a free living bacteria that came inside a eukaryotic cell and started a mutual relationship with the eukaryotic cell. The bacteria got to have a shelter, and in return, the eukaryotic is able to create more energy by mitochondrias, or be able to convert from co2 to o2. It is only a theory though.

Identify two exceptions to the cell theory?
Exception to "every cell came from another cell": The first cell ever. (Controversial) exception to "a cell is the smallest unit of life"/"all life is made of cells": viral matter. Hope this helps!

What is the origin of the word organelle?
The word "organelle" is from Modern Latin, from 1909. It came from the Latin word "organum," meaning "instrument, organ." Please see the related link below.
What is biologists Lynn margulis's hypothesis about where the first protists came from?
Lynn Margulis proposed the endosymbiotic theory, suggesting that organelles such as mitochondria and chloroplasts in eukaryotic cells evolved from symbiotic relationships between different types of prokaryotic cells. This hypothesis explains the origins of protists and other eukaryotic organisms through the merging of different cell types rather than gradual evolution from a single organism.
