What are the similarities between mitochondria an chloroplast?
Both mitochondria and chloroplasts are organelles. Mitochondria are used in cellular respiration and chloroplasts are used in photosynthesis. Photosynthesis and cellular respiration are opposite processes. Both are believed to have evolved from a living single celled bacteria that was engulfed by an early form of a plant or animal cell. Therefore, both mitochondria and chloroplasts have their own DNA. Furthermore, they both have free ribosomes. NOTE! they both DO NOT have 2 membranes. chloroplasts have 3 membranes
What features of chloroplasts and mitochondria could be used to support the notion that symbiosis provided a foothold for their development?
Symbiosis interaction between two or more different biological species. Both mitochondria and chloroplasts can arise only from preexisting mitochondria and chloroplasts. Therefore this notion is not factual.
What are the primary three elements that cycle between the mitochondria and chloroplast?
The primary three elements that cycle between mitochondria and chloroplasts are carbon, oxygen, and hydrogen. In chloroplasts, carbon dioxide is fixed during photosynthesis, producing glucose and releasing oxygen. Mitochondria then utilize the glucose in cellular respiration to generate energy, consuming oxygen and releasing carbon dioxide and water. This cyclical process supports energy flow in ecosystems.
What does the endosymbiotic theory purpose?
concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

What are similarities between mitochondria and chloroplasts?
They both have their own DNA. In addition, it has been observed that they divide on their own during cell division. They also both have two membrane as opposed to one membrane in rest of the organelles (except for the nucleus). They are also similar because they are both Organ cells.
What is the main diffrence between chloroplasts and mitochodria?
Chloroplasts consume energy to produce glucose. Mitochondria liberate energy by burning the glucose. That means there is biological reduction in chloroplasts and biological oxidation in mitochondria.
Does an animal mitochondrion contain functional ribosomes?
Yes, chloroplasts, like mitochondria, contain ribosomes.Chloroplasts also contain DNA, and synthesize messenger RNA by transcription. Polypeptides are formed at the ribosomes.These ribosomes are more or less like those of modern prokaryotic cells; this is one of the facts that supports the theory that chloroplasts and mitochondria evolved from ancestral free-living prokaryotic organisms.
What are differences between the mitochondria and chloroplast?
Chloroplasts use visible light to fix carbon (obtained from carbon dioxide) into sugars. They are found in plants as well as small organisms.Mitochondria break down simple sugars into carbon dioxide and create energy in the form of ATP and NADPH.the mitochondria change chemical energy stored in food into compounds that are more convenient for the cell to use while the chloroplast is the only organelle that can trap the energy of sunlight and convert it into chemical energy.
Difference of chemiosmosis in chloroplasts and mitochondria?
Well, I know that in mitochondria, protons are pumped from the matrix to the intermembrane space; however, in chloroplasts, protons are pumped from the stroma to the thykaloid space.I am not sure if that is the only difference, though ^^'

What is the evidence for the endosymbiosis hypothesis?
Evidence for the endosymbiosis hypothesis includes similarities between mitochondria/chloroplasts and bacteria (such as DNA structure and ribosomes), the ability of mitochondria/chloroplasts to replicate independently within cells, and historical precedence in the evolution of eukaryotic organisms. Additionally, the presence of a double membrane in mitochondria and chloroplasts supports the idea that these organelles were once free-living bacteria that were engulfed by an ancestral eukaryotic cell.
How did mitochondria and chloroplasts most likely arise in eukaryotic cells?
Mitochondria and chloroplasts most likely arose in eukaryotic cells through a process called endosymbiosis, where a host cell engulfed a prokaryotic cell. Over time, the prokaryotic cell evolved to become an organelle within the host cell, forming a symbiotic relationship. This theory is supported by the similarities between mitochondria and chloroplasts and modern-day bacteria.
The stongest evidence for the endosymbiotic origin of eukaryotic orgelles is the homology between extant prokaryotes and?
...eukaryotic organelles, such as mitochondria and chloroplasts. These organelles have their own DNA, ribosomes, and are similar in size to prokaryotes like bacteria. Additionally, the double membrane structures of mitochondria and chloroplasts resemble what is seen in prokaryotic cells.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
What is the function difference between chloroplasts and mitochondria?
The Difference: the major difference between chloroplast and mitochondria is that the latter contains thylakoid membrane and pigment molecules, whereas the mitochondria membranes contain respiratory enzymes not found in chloroplast membrane. Similarities: They both are the main powersource of the organism.(Mitochondria producing ATP through the krebs cycle and chloroplast uses photosynthesis to produce glucose.)

Symbiosis interaction between two or more different biological species. Both mitochondria and chloroplasts can arise only from preexisting mitochondria and chloroplasts. Therefore this notion is not factual.
The difference between photosynthesis in chloroplasts and cellular respiration in the mitochondria?
Photosynthesis makes glucose molecules, but cellular respiration breaks them down.
