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.
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 are found in all protists lineages?
All protists have a nucleus and are eukaryotic. They can be unicellular or multicellular, and they exhibit diverse modes of nutrition such as autotrophic, heterotrophic, or mixotrophic. Additionally, protists possess various organelles like mitochondria, plastids, and flagella.
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 is responsible for supplying energy for the cell?
The cell feature that is responsible for making proteins are the ribosomes.
What is a common feature of mitochondria and plastids?
ATP
What organ has the same function as a mitochondria?
Plastids
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.
What is the difference between Mitochondria and plastids?
The similarity between the two is that both of them have their own DNA and ribosomes. Therefore, they are able to prepare their own protiens. Plastids and Mitochondria have a similar external structure. Both have two membrane covering instead of just one.
Compare and contrast mitochondria and plastic?
the mitochondria is the vital activities of the cell while plastids are manufacture in food photosynthesis.
What organelle in the cell produces carbohydrates?
Mitochondira

Name the two organelles in a plant cell that contains their own genetic material and ribosomes?
mitochondria and plastids

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.

What organelles are associated with endoymbiont theory?
Plastids (include chloroplasts) and mitochondria contain their own DNA are considered to be endosymbionts. Some think that flagella and cilia may also be but that is rather controversial. Those plastids that contain pigments can carry out photosynthesis. Plastids can also store products like starch and can synthesize fatty acids.
