Red blood cells are unique in that they have no nucleus or mitochondria. The lack of this organelle means that red blood cells must get their energy differently using a process called glycolysis to produce ATP. The lack of organelles means that there are various advantages and disadvantages that are considered. One advantage is the biconcave disk shape of the mammalian erythrocytes, which optimizes the cell for the exchange of oxygen with its surroundings and to make maximum space for hemoglobin. The cells are flexible in order to fit through tiny capillaries, where they release their oxygen load. On the other hand, the disadvantage is that because of the lack of nuclei and organelles, mature red blood cells do not contain DNA and cannot synthesize any RNA, and consequently they cannot divide or repair themselves, limiting their lifespan. Mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive. The lack of mitochondria means that the cells use none of the oxygen they transport; instead they produce the energy carrier ATP by fermentation, via glycolysis of glucose followed by lactic acid production.

RPCProkariyotic cells do not have any.Some eukariyotic cells like mammalian RBC lack mitochondria
In human, mature RBC (Red Blood Corpuscles) do not have mitochondria.
Reticulocytes and Erythroblasts are two types of red blood cells that contain a high number of mitochondria. Reticulocytes are immature red blood cells in the process of maturing, and erythroblasts are precursor cells that mature into red blood cells, both requiring energy for their development processes.
Red blood cells rely on anaerobic metabolism for ATP production because they lack mitochondria and thus cannot perform aerobic respiration.
Red blood cells require glucose as their primary source of energy to carry out functions such as transporting oxygen from the lungs to the rest of the body and removing waste products like carbon dioxide. Glucose is metabolized in the red blood cells to produce ATP, which is essential for maintaining their structure and function.
White blood cells have. But erithrocytes lack many
Mitochondria not found in RBC,Terminal keratinocytes.
Red blood cells do not have nuclei or mitochondria.
The animal with the least amount of cells is a worm
red blood cells
Yes, but not very much. Red blood cells lack most of the typical organelles of a cell, including a nucleus and mitochondria.
Red blood cells do not have endoplasmic reticulum.
It is fact not supposition .

Prokariyotes do not have mitochondria. But they have ribosomes
No they do not have.They also lack a nucleus and mitochondria.
