Why do Biologists suspect endosymbiosis gave rise to mitochondria before plastids?
Biologists suspect that mitochondria arose before plastids through endosymbiosis because mitochondria are present in almost all eukaryotic cells, while plastids are only found in photosynthetic eukaryotes. Additionally, mitochondria share more structural and functional similarities with their bacterial ancestors than plastids do.
Which cell organelles is called kitchen of the cell?
Chloroplast is known as the kitchen of cell not Mitochondria. Chloroplast have a pigment called chlorophyll and they are involved in the photosynthesis of food that's why known as kitchen of cell.
What does the theory of endosymbiosis explain?
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.

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 ^^'
Are plastids found in animal cells?
Plastids are generally not found in animal cells. They are typically only present in plant cells and some protists. Animal cells do not have plastids as they do not perform photosynthesis, which is the primary function of plastids.
What is common feature of mitochondria and plastids?
ATP
What organ has the same function as a mitochondria?
Plastids
What is a common feature of mitochondria and plastids?
ATP

Compare and contrast mitochondria and plastic?
the mitochondria is the vital activities of the cell while plastids are manufacture in food photosynthesis.
What is the main difference between plant and animal cells pertaining the presence of plastids?
On the basis of plastids a plant cell can be recognized from animal cell. The plant cells have several plastids including chloroplasts. Animal cells are characterized by their abscence.
What organelle in the cell produces carbohydrates?
Mitochondira
Mitochondria and plastids likely formed in eukaryotes in what way?
Mitochondria likely formed through endosymbiosis with an aerobic bacterium, while plastids likely formed through endosymbiosis with a photosynthetic cyanobacterium. Both organelles have their own DNA and replicate independently within eukaryotic cells.
What is the difference between respiration and mitochondria?
Respiration is a process. It takes place in organelle ,mitochondria
Name the two organelles in a plant cell that contains their own genetic material and ribosomes?
mitochondria and plastids
Why are mitochondria and plastids called semiautonomous membrane?
Mitochondria and plastids are called semiautonomous because they contain their own DNA and ribosomes, allowing them to partially control their own replication and functioning. However, they still rely on the cell for certain essential components and cannot survive independently. The membrane part refers to their double-membrane structure that surrounds the organelles.
What part of the plant is the?
Other than the cells themselves, the mitochondria (or perhaps other plastids), are much smaller and more numerous.
