Question

mature RBC in mammals do not have cell organelles​

Answer 1

Explanation:

mature mammalian red blood cells lack nuclei, mitochondria and rough endoplasmic reticulum, they do not contain DNA and consequently cannot divide. They also cannot synthesize RNA nor synthesize any new proteins, and consequently have a limited life span.

Answer 2

Answer:

Since mature mammalian red blood cells lack nuclei, mitochondria and rough endoplasmic reticulum, they do not contain DNA and consequently cannot divide. They also cannot synthesize RNA nor synthesize any new proteins, and consequently have a limited life span.

Explanation:

Mature mammalian RBC does not contain membrane-bounded cell organelles. Mammalian RBC is biconcave, circular, nonnucleated cell. Their cytoplasm is rich in hemoglobin, an iron-containing biomolecule, that can bind oxygen and is responsible for the red color of the cells. The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiological cell function, such as deformability and stability, while traversing the circulatory system and specifically the capillary network. In humans, mature red blood cells are flexible and oval, biconcave disks. They lack a cell nucleus and most organelles in order to accommodate maximum space for hemoglobin.
