Question

Why animals have more mitochondria as compared to plant?

Answer 1

Answer:

Mitochondria are the energy factories of the cells. The energy currency for the work that animals must do is the energy-rich molecule adenosine triphosphate (ATP). The ATP is produced in the mitochondria using energy stored in food. Just as the chloroplasts in plants act as sugar factories for the supply of ordered molecules to the plant, the mitochondria in animals and plants act to produce the ordered ATP molecules as the energy supply for the processes of life.

A typical animal cell will have on the order of 1000 to 2000 mitochondria. So the cell will have a lot of structures that are capable of producing a high amount of available energy. This ATP production by the mitochondria is done by the process of respiration, which in essence is the use of oxygen in a process which generates energy. This is a very efficient process for using food energy to make ATP. One of the benefits of "aerobic exercise" is that it improves your body's ability to make ATP rapidly using the respiration process.

All living cells have mitochondria. Hair cells and outer skin cells are dead cells and no longer actively producing ATP, but all cells have the same structure. Some cells have more mitochondria than others. Your fat cells have many mitochondria because they store a lot of energy. Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work. Mitochondria occupy 15 to 20 percent of mammalian liver cells according to Karp.

Answer 2

Answer:

• Animals have more mitochondria than compared to plant cells because animals are mobile while plants are not.

Explanation:

• Mitochondria is called as the ' Powerhouse of the Cell' because it is the site of the cellular respiration and the ATP cycle which produces energy in the cells.

• Because animals moves from one place to another and also they move large distances in search of their food and to protect themselves from predators, they need more mitochondria to produce more energy for them

• Generally, mitochondria is present in the muscle cells of the animals, which plays a significant role in producing energy by which the animals move.

• Plants do not need to move from one place to another in search of food because they make their own food. Also plants do not need to run away to protect themselves from predators because for this they have developed various adaptations.

• So, they do not need more energy as compared to animals and hence they have fewer mitochondria as compared to animal cells.
