Is mitochondria in plant and animal cells?

Is mitochondria in plant and animal cells?

Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.

What types of eukaryotic cells contain mitochondria?

Today, mitochondria are found in fungi, plants, and animals, and they use oxygen to produce energy in the form of ATP molecules, which cells then employ to drive many processes.

Which types of cells have the most mitochondria?

Muscle cells have the most number of mitochondria in a human body.

Are mitochondria found in prokaryotic cells?

Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.

Is mitochondria a bacterial cell?

Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do.

Where is mitochondria in the cell?


Do human cells have mitochondria?

The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.

What type of cell is plantae?


Why doesn’t a bacterial cell contain mitochondria?

They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.

What is the function of mitochondria in prokaryotes?

Each organelle supports different activities in the cell. Mitochondria, for example, are organelles that provide eukaryotes with most of their energy by producing energy-rich molecules called ATP. Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.

Do mitochondria have a cell wall?

Mitochondria possess inner and outer membranes, with the inner membrane consisting of folds called cristae. The outer mitochondrial membrane and the cell wall of bacteria also contain similar structures.

What is the main function of cristae in mitochondria?

Function. The cristae greatly increase the surface area of the inner membrane on which the above-mentioned reactions may take place. A widely accepted hypothesis for the function of the cristae is that the high surface area allows an increased capacity for ATP generation.

What does the inner membrane do in the mitochondria?

The mitochondrial inner membrane is the site of the electron transport chain, an important step in aerobic respiration. Between the inner membrane and outer membrane is the inter-membrane space. There, H+ ions build up to create a proton potential that helps power the ATP energy formation.

Why does Mitochondria have 2 membranes?

Mitochondria Structure They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The folding of the inner membrane increases the surface area inside the organelle.
