Detailed explanation-1: -Within eukaryotic cells, mitochondria function somewhat like batteries, because they convert energy from one form to another: food nutrients to ATP. Accordingly, cells with high metabolic needs can meet their higher energy demands by increasing the number of mitochondria they contain.

Detailed explanation-2: -Definition. Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Detailed explanation-3: -Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.

Detailed explanation-4: -Prokaryotic cells do not have mitochondria. Most prokaryotes rely on their immediate environment to obtain energy. This process is facilitated by the electron transport chains in the plasma membrane. Mitochondria are only found in eukaryotic cells.

Detailed explanation-5: -Eukaryotic cells may contain anywhere from one to several thousand mitochondria, depending on the cell’s level of energy consumption. Each mitochondrion measures 1 to 10 micrometers (or greater) in length and exists in the cell as an organelle that can be ovoid to worm-shaped to intricately branched.
