An immature red blood cell containing a netlike pattern inside is called

• A. Reticulocyte.
• B. Sanguineous.
• C. Cytoblast.
• D. Sanguinocyte.

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the context of the question, which is about identifying a specific type of immature red blood cell based on its characteristics.
2. Step 2: Recall that immature red blood cells are called erythroblasts or reticulocytes depending on their stage of development and features.
3. Step 3: Recognize that a reticulocyte is an immature red blood cell that contains a netlike (reticular) pattern of ribosomal RNA visible with special staining techniques.
4. Step 4: Differentiate the term 'reticulocyte' from other options: 'Sanguineous' relates to blood but is an adjective, 'Cytoblast' refers to a precursor cell but not specifically an immature red blood cell, and 'Sanguinocyte' is not a standard medical term.
5. Step 5: Conclude that the correct term for an immature red blood cell with a netlike pattern inside is 'Reticulocyte'.
