Do mitochondria and chloroplasts have ribosomes that are similar in size and structure to those of bacteria?
Yes, they do - this is one piece of evidence used to support the endosymbiotic theory. This states that Eukaryotic cells arose from Prokaryotic cells that engulfed other Prokaryotic cells. The DNA found in mitochondria and chloroplasts is similar in size and shape (circular) to that of bacteria.
Discuss evidence that supports the endosymbiotic theory of eukaryotic evolution?
1.) Mitochondria and plastids are relatively the same size as bacteria 2.) Mitochondria and plastids have nucleiod DNA molecules - just like bacteria. 3.) Mitochondria and plastids reproduce the same way as bacteria - binary fission.
What evidence do scientists have to support their ideas?
The strongest piece of evidence for the endosymbiotic theory is the fact that mitochondria and chloroplasts have their own circular DNA, prokaryote fashion, and can still replicate, transcribe and translate some proteins. Their ribosomes are also fashioned as a prokaryotes would be.
Which of the following are not goal-setting steps?
Which of the following are not goal-setting steps? Check all that apply.
In response to peer review a scientific journal might choose not to publish a paper submitted by a scientist. Which of the following is a reason why a paper might be rejected for publication?
Apex.The experimental results failed to support the conclusion.
What statement fails to support the endosymbiotic theory?
A statement that fails to support the endosymbiotic theory would be one that asserts that all eukaryotic organelles were independently formed within the cells, without any symbiotic relationship with prokaryotic cells. This contradicts the evidence and principles of the endosymbiotic theory, which suggests that organelles like mitochondria and chloroplasts originated from ancient symbiotic relationships between prokaryotic cells and ancestral eukaryotic cells.
The endosymbiotic theory was supported by the scientist?
Lynn Margulis was the scientist who proposed and championed the endosymbiotic theory. She provided evidence to support the idea that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms.
What are factw about mitochondria and chloroplasts constitution support for the endosymbiont theorym?
There are three characteristics of mitochondria and chloroplasts that support this theory. First, both mitochondria and chloroplasts have two membranes surrounding them. Second, like prokaryotes, mitochondria and chloroplasts contain ribosomes, as well as a circular DNA molecules attached to their inner membranes. Third, mitochondria and chloroplasts are autonomous.
Which 2 organelles help to support the plant cell?
Mitochondria & Chloroplasts
Which organelles support life processes in plant cells but are not found in animal cells?
chloroplasts
Which of the following do typical plant cells have that typical animal cells do not?
Typical plant cells have cell walls, chloroplasts, and large central vacuoles, which are structures that are not typically found in animal cells. These features help plants to support their structure, perform photosynthesis, and store nutrients and waste products.
What do only plant cells posses?
Plant cells possess chloroplasts, cell walls made of cellulose, and large central vacuoles. Chloroplasts are responsible for photosynthesis, cell walls provide structural support, and vacuoles help maintain turgor pressure and store nutrients.
Do the stems of woody stem plants have chloroplasts?
No, the stems of woody plants do not have chloroplasts. Chloroplasts are primarily found in the leaves of plants where photosynthesis occurs. Woody stems provide structural support and conduct water and nutrients throughout the plant.
Which kingdom has cellulose walls and chloroplasts in some?
The kingdom Plantae has cellulose walls and chloroplasts in some of its members. Plants are the primary organisms that have these characteristics and are essential for photosynthesis and providing structural support.
Do mitochondria and chloroplasts have ribosomes that are similar in size and structure to those of bacteria?
Yes, they do - this is one piece of evidence used to support the endosymbiotic theory. This states that Eukaryotic cells arose from Prokaryotic cells that engulfed other Prokaryotic cells. The DNA found in mitochondria and chloroplasts is similar in size and shape (circular) to that of bacteria.
Which of the following methods of support is providing support to a maintenance unit?
backup support
What is found in a plant cell but not in a animal cell?
A cell wall and chloroplasts are found in plant cells but not in animal cells. The cell wall provides structure and support to the plant cell, while chloroplasts facilitate photosynthesis, allowing plants to generate their own food.
