how are mitochondria and chloroplasts similar to prokaryotes?
135185
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.

Prokaryotes lack mitochondria and chloroplasts. Instead, processes such as oxidative phosphorylation and photosynthesis take place across the prokaryotic cell membrane. However, prokaryotes do possess some internal structures, such as prokaryotic cytoskeletons.

Prokaryotic Cell. Prokaryotic cells lack both, a well-defined nucleus and membrane-bound cell organelles. Examples of prokaryotes are blue-green algae, bacteria and mycoplasma. Among prokaryotes, bacteria are the most common and multiply very fast.

How are prokaryotic and eukaryotic cells similar? They both have DNA, cytoplasm, ribosomes, and a cell membrane. ... Prokaryotic cells are unicellular and eukaryotic cells are either unicellular (protists) or multi-cellular(plants, fungi, and animals).
1286927
Eukaryotes and prokaryotes both have DNA, but it is only enclosed in a membrane in eukaryotic cells. ... In general, prokaryotic cells do not have a true nucleus or membrane-bound organelles, whereas eukaryotic cells contain both a nucleus and organelles enclosed by membranes.

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.

Mitochondria and chloroplasts are similar in size and features to prokaryotes. The deep folds of the inner mitochondrial membrane, called cristae, resemble the folds in the prokaryotic cell, called mesosomes.

Even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. ... Chloroplasts transform light energy into the chemical energy of ATP. Mitochondria can be found in animal cells and Chloroplasts can be found in plant cells.
1116647
The organelles are thought to have been acquired as a result of the association of prokaryotic cells with the ancestor of eukaryotes. ... Mitochondria and chloroplasts thus contain their own genetic systems, which are distinct from the nuclear genome of the cell.
358805
Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live.

They are a lot ! To be simple : Both are multicellular organisms, eucaryotes (each cell has a nucleus) with various organits : mitochondria to provide the cells with chemical energy... but chloroplasts are observed in plants only.

Mitochondria and Plastids are very important cell organelles that perform different functions. The main difference between Mitochondria and Plastids are that plastids are present only in plants, mitochondria, on the other hand, are present in all eukaryotic cells.
1039788
Mitochondria and Chloroplasts Mitochondria within animal cells and chloroplasts within plant cells look like prokaryotes. ... Chloroplasts, like mitochondria, produce energy for plant cells. Both mitochondria and chloroplasts have their own circular DNA and can function independently of the eukaryotic host cell.

Prokaryotes are organisms whose cells lack a nucleus and other organelles. ... Most prokaryotes are small, single-celled organisms that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm.
210453
Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus that holds genetic material as well as membrane-bound organelles.
448050
Both organisms are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane. The biggest difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus. They also have other membrane structures called organelles.

Mitochondria are responsible for cellular respiration and energy metabolism. ... Mitochondria are present in the cells of all types of aerobic organisms like plants and animals, whereas Chloroplast is present in green plants and some algae, protists like Euglena. Mitochondria is the colourless, bean shape organelles.
