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.
What else can I help you with?
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.
How would chloroplasts and mitrochonhdria work together in a plant cell?
Chloroplasts and mitochondria work together in plant cells to support energy metabolism. Chloroplasts capture sunlight and convert it into chemical energy through photosynthesis, producing glucose and oxygen. This glucose serves as a fuel source for mitochondria, which then perform cellular respiration to generate ATP, the energy currency of the cell. Together, these organelles facilitate the flow of energy from sunlight to chemical energy and finally to usable energy for cellular activities.
How do the finding of margulis and other scientists-that mitochondria and cholarplasts have third own DNA like a cell nucleus-support the hypothesis of endosymbiosis?
concept that mitochondria and chloroplasts are the result of years of evolution initiated by the endocytosis of bacteria and blue-green algae which, instead of becoming digested, became symbiotic.
Why are mitochondria and chloroplast so important?
Mitochondria are known as the powerhouse of the cell because they generate energy in the form of ATP through cellular respiration. Chloroplasts are essential for photosynthesis, converting sunlight into energy-rich molecules such as glucose. Both organelles play critical roles in providing energy to support cellular functions and overall plant and animal growth and development.
How does the internal structure with these organelles support mitochondria and chloroplast's function?
The internal structure of mitochondria and chloroplasts, with their highly folded inner membranes, increases surface area for more efficient energy production. This structure also allows for compartmentalization of specific metabolic processes, enabling enzymes and other molecules to be concentrated and organized for optimal function. Additionally, the presence of unique structures such as cristae in mitochondria and thylakoid membranes in chloroplasts play key roles in ATP production and photosynthesis, respectively.
Which 2 organelles help to support the plant cell?
Mitochondria & Chloroplasts
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 cell has a cell wall many organelles including mitochondria a nucleus a vacuole and several chloroplasts?
This description fits a plant cell. Plant cells have a cell wall for structural support, various organelles like mitochondria and chloroplasts for energy production, a nucleus for genetic material control, and a large central vacuole for storage and structural support.
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.

After ln margulis's endosymbiont theory met oppositon what new evidnece emerged in support of the theory?
main distinction between euayotes and prokaryotes
What does a plant cell consist of?
A plant cell consists of a cell wall, cell membrane, cytoplasm, nucleus, and various organelles such as chloroplasts, vacuoles, and mitochondria. These components work together to support the cell's structure, function, and growth.
What cellular structures are found in plant cells but NOT in animal cells?
mitochondrial

Which cellular organelles replicate in the G1 phase of the cell cycle?
Organelles such as the mitochondria and the chloroplasts replicated in the G1 phase of the cell cycle. This is so that when the cell divides, no parts are lost.
Are plants intracellular or extracellular?
Plants have both intracellular and extracellular components. Intracellularly, plants have organelles like chloroplasts, mitochondria, and nuclei within their cells. Extracellularly, plants have cell walls made of cellulose that provide structural support and protection to the cells.
