Human RBC has no nucleus, no mitochondria and no endoplasmic reticulum. Which of

these functions could or could not be carried out by a human red blood cell? In each case

justify your answer.

a) protein synthesis b) cell division c)lipid synthesis d)active transport

Human RBCs cannot carry out protein synthesis and lipid synthesis. This is because RBCs contain no nucleus,  mitochondria,  golgi apparatus or endoplasmic reticulum which are essential to carry out these processes. Also, they cannot go through the process of cell division because of the absence of nucleus. They are formed in the long bones of bone marrow. They live for 120 days only. Bone marrow continuously make up for this loss by its production of RBCs.
Human RBCs have an essential role only in the active transport of oxygen and carbon dioxide. They are filled with haemoglobin on the inside which helps them to carry out this transport successfully.
