Why does a bacterial cell not contain a mitochondria?

Answer 1

Bacterial cells don't perform the krebs cyce or oxidative phosphorylation steps of cellular respiration and therefore do not need mitochondria. Bacteria only perform glycolysis which is done in the cytoplasm to convert glucose into ATP to drive cellular work.

Answer 2

While there are no clear evidences that plant cells do contain fewer number of mitochondria, if such claim is true, it is probably because of the number of other organelles which occupy the space. Organelles such as the large central vacuole (which takes up most of the space available in a plant cell) and plastids such as chloroplasts might be occupying the space that in animal cells, are occupied by lysosomes or more mitochondria.

Another reason why they might have fewer mitochondria is because of plant's less necessity of the organelle. Since plants are sessile and do not contain many parts within an animal cells that require large amounts of ATP, plants should be able to live with fewer mitochondria.

Answer 3

Bacterial cells do not contain mitochondria because they are prokaryotic organisms, lacking membrane-bound organelles like mitochondria found in eukaryotic cells. Prokaryotes generate energy through processes like glycolysis and electron transport chain in the cell membrane, without the need for specialized organelles like mitochondria.

Answer 4

Plants don't move - they require less energy. The cells with the most mitochondria are muscle cells, the cells that are responsible for movement in animals.

Answer 5

Bacteria are prokaryotic organisms. They do not have membrane bound organells.

Answer 6

Yes because they need energy dummass
