Final answer:
The statement that mitochondria can change their location, shape, and number to meet cellular needs is true. They adapt dynamically to the energy demands of the cell and can undergo processes like fission and fusion, independently replicating and moving across the cell.
Step-by-step explanation:
True or False: Mitochondria can change their location, shape, and number in the cell to suit the needs of a cell. The statement is TRUE. Mitochondria are dynamic organelles that can indeed alter their location, shape, and number within a cell, adapting to the cell's metabolic requirements. These changes are essential for the maintenance of cell homeostasis and the cell's ability to respond to metabolic demands.
Mitochondria, often referred to as the cell's "power plants," are double-membraned organelles responsible for producing ATP, which is the primary energy currency in the cell. They have their own DNA and ribosomes, which permit them to replicate independently of the cell cycle. Cellular energy demand dictates the number of mitochondria, with energy-intensive cells like muscle and nerve cells containing many mitochondria, whereas less active cells contain fewer.
The shape and distribution of mitochondria within the cell can change through processes such as fission and fusion. Mitochondria undergo fission to increase their number, particularly when a cell's energy demands increase. Conversely, fusion can help mitochondria mix their contents, which can be beneficial for mitochondrial health and function. Moreover, mitochondria are capable of moving within the cell to areas where energy requirements are higher.
