NEET BIOLOGY

Detailed explanation-1: -Sperm cells and muscle cells need lots of energy. What do they have in common? They have lots of mitochondria. Mitochondria are called the power plants of the cell, as these organelles are where most of the cell’s energy is produced.

Detailed explanation-2: -Sperm cells need a lot of energy to go toward the egg in order to fertilize it, hence they need a lot of mitochondria to power them. Mitochondria are located in the center of sperm. It is necessary to supply the sperm with the energy to move.

Detailed explanation-3: -Liver cells contain 1000-2000 mitochondria in each cell. Heart, sperms, and muscle cells contain about 5, 000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body.

Detailed explanation-4: -Muscles require a large amount of energy to function. This is provided primarily by mitochondria in cells that consume a lot of energy. We therefore find more of these powerhouses of the cell in muscle cells than in other cell types with a lower metabolic rate.

Detailed explanation-5: -Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells.
