What are two pieces of evidence supporting Endosymbiotic theory?

What are two pieces of evidence supporting Endosymbiotic theory?

The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.

Which of the following best describes an endosymbiont?

Which of the following best describes an endosymbiont? A cell that lives within another cell. The theory of endosymbiosis best explains: How eukaryotic cells evolved from a prokaryotic cell engulfing another prokaryotic cell.

Which type of cell makes up both protists and fungi?

Eukaryotes. Organisms can be divided into two categories: prokaryotes and eukaryotes. The prokaryotes include bacteria and some primitive single-celled organisms, while the eukaryotes include plants, animals, fungi and protists.

What does the host cell receive from its endosymbiont?

In the example of corals, the host animal is a multicellular cnidarian, and the endosymbiont is a unicellular alga called a dinoflagellate. The host animal serves as a protected environment, providing the alga with a constant supply of nutrients in the form of nitrogen, phosphorus, and sulfur.

Which of the following is a structure that is present in both eukaryotic and prokaryotic cells?

Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.

What statement best describes the cell after 20 minutes?

The statement that describes the cell after twenty minutes is this: WATER WILL MOVE FROM THE CELL INTO THE BEAKER RESULTING IN A SMALLER CELL.

What structures do eukaryotic cells have that prokaryotic cells do not?

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
