Answer 1

Red Blood Corpuscles:

1. The Red Blood Corpuscles (RBCs)/ Erythrocytes are the most abundant type of cells found in the blood.
2. The RBCs are red-colored due to the presence of haemoglobin.
3. These are biconcave disc-shaped cells.

Enucleated RBCs:

1. When RBCs mature, they become enucleated, that is they lack nucleus.
2. This gives the red blood cells a biconcave appearance.

The red blood corpuscles are biconcave and disc shaped cells without nucleus.
