Detailed explanation-1: -Endoplasmic reticulum is absent in mature RBCs.
Detailed explanation-2: -Answer and Explanation: Red blood cells are commonly known for not having nuclei, but they actually lack most organelles, including the Golgi apparatus, endoplasmic reticulum, and mitochondria.
Detailed explanation-3: -Like most animal cells, red blood cells from fish, amphibians, reptiles and birds all contain DNA in nuclei, represented by shaded ovals in Gulliver’s drawing. By contrast, the red blood cells of mammals lack nuclei and other internal structures found in most animal cells.
Detailed explanation-4: -Red blood cell structure is very simple compared to other cell types as they have no organelles. The most common blood cell type, these biconcave cells have no organelles. A mature red blood cell is an anucleate cell – it has no nucleus. This means it contains no DNA.
