When were important cell theory discoveries made?
Its Important because my Teacher Sucks ball!!
What is another theory for the formation of organelles?
Endosymbiotic theory proposes that some organelles, such as mitochondria and chloroplasts, were once free-living prokaryotic organisms that were engulfed by a larger host cell, forming a symbiotic relationship over time. This theory is supported by the presence of unique DNA within mitochondria and chloroplasts, as well as their ability to replicate independently within the cell.
What is the ancestor of mitochondria?
One hypothesis is that mitochondria are "swallowed" bacteria that were not digested but instead incorporated into the cell as a symbiont (helper). Mitochondria have a membrane similar to the cell membrane and their own genetic material similar to bacteria.
What did virchowschleidan and schwann each contribute to the cell theory?
The name of the theory that Schleiden and Schwann developed is the cell theory.
What is the evolutionary hypothesis that some organelles are remnants of prokaryotic cells?
The endosymbiotic theory proposes that some organelles, such as mitochondria and chloroplasts, were once free-living prokaryotic cells that were engulfed by a host cell through endocytosis. Over time, these prokaryotic cells formed a symbiotic relationship with the host cell, eventually evolving into permanent organelles within the eukaryotic cell.
Which technology was important to the discovery of the cell theory?
The Microscope.
Mitochondria existed on its own outside the cell?
Mitochondria have their own DNA separate and distinct from the cells DNA. It is believed that mitochondria were once separate from cells and have since developed a symbiotic relationship with them.
Who made an important discovery that led up to the Cell Theory?
Theodore Schwann, Matthias Schlieden, Rudolph Virchow. They all made very important contributions to the cell theory.
Why do Mitochondrial have DNA?
Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNATo provide some autonomy for its function the mitochondria have their own DNA. One cell theory states that some bacteria invaded the cell and established a symbiotic relationship. Mitochondria and chloroplasts are such microbes establishing permanent symbiotic relationship with the plant cell.
What is the Symbiotic Theory?
The Symbiotic Theory suggests that organisms can mutually benefit from living closely together, forming a symbiotic relationship. This theory highlights the interdependence between different species and how they can evolve together in a mutually beneficial way. Examples include the relationship between bees and flowers, where bees pollinate flowers while obtaining nectar for themselves.

What process is thought to be involved in the genesis of eukaryotes from prokaryotes?
It is almost certain that DNA-bearing organelles like the mitochondria and the chloroplasts are what remains of ancient symbiotic oxygen-breathing proteobacteria and cyanobacteria, respectively, where the rest of the cell seems to be derived from an ancestral archaean prokaryote cell - a theory termed the endosymbiotic theory.

Where is mitochondrain evolved from?
From an aerobic bacteria. Explained by endo symbiotic theory

What statement best supports the theory that eukaryotic cells evolved through endosymbiosis?
The presence of organelles like mitochondria and chloroplasts with their own DNA and membrane structure closely resembling that of bacteria supports the theory of endosymbiosis, where a prokaryotic cell engulfed another prokaryotic cell and formed a symbiotic relationship over time. Additionally, the fact that these organelles replicate independently of the host cell and have similarities to certain types of bacteria further strengthens the endosymbiotic theory of eukaryotic cell evolution.

The name of the theory that Schleiden and Schwann developed is the cell theory.
