    Correct Answer
    B. Eosinophil
    Explanation
    The arrow in the image points to a cell with granules, indicating that it is an eosinophil. Eosinophils are a type of white blood cell that are involved in the immune response against parasitic infections and allergic reactions. They contain granules filled with enzymes that help to kill parasites and modulate inflammation.

      Shistocyte (red cell fragment)

    Correct Answer
    B. Ovalocytes or Elliptocyte
    Explanation
    The correct answer is Ovalocytes or Elliptocyte because ovalocytes are red blood cells that have an oval or elliptical shape instead of the usual round shape. They can be identified by their elongated appearance and can be seen in certain conditions such as hereditary elliptocytosis or certain types of anemia.

    Correct Answer
    C. Polychromatic RBC
    Explanation
    The correct answer is Polychromatic RBC. The arrow is pointing towards a cell that appears to have a bluish tint, indicating that it is a polychromatic red blood cell. Polychromatic RBCs are immature red blood cells that still contain remnants of their nucleus and are commonly seen in conditions such as anemia or bone marrow disorders.

      Basophil

    • D.

      Plasma Cell

    Correct Answer
    B. Monocyte
    Explanation
    The cell identified by the arrow is a monocyte. Monocytes are a type of white blood cell that are responsible for phagocytosis, which is the process of engulfing and destroying pathogens. They are larger than other white blood cells and have a kidney-shaped nucleus. Monocytes are a crucial part of the immune system and play a role in defending the body against infections and diseases.

    • D.

      Segmented Neutrophil

    Correct Answer
    D. Segmented Neutrophil
    Explanation
    The correct answer is Segmented Neutrophil because the arrow is pointing to a cell that has a segmented nucleus, which is a characteristic feature of neutrophils. Monocytes have a kidney-shaped nucleus, lymphocytes have a round nucleus, and basophils have a lobed nucleus. Therefore, the cell in question matches the characteristics of a segmented neutrophil.

    • B.

      Platelet

    • C.

      Stomatocyte

    • D.

      Spherocyte

    Correct Answer
    D. Spherocyte
    Explanation
    The cell identified by the arrow is a spherocyte. Spherocytes are abnormally shaped red blood cells that appear smaller and more dense than normal RBCs. They lack the central pallor and have a spherical shape, resulting in decreased surface area for gas exchange. Spherocytes are commonly seen in conditions such as hereditary spherocytosis and autoimmune hemolytic anemia.

    • C.

      Spherocyte

    • D.

      Target Cell (Codocyte)

    Correct Answer
    A. Tear Drop Cell (Dacryocyte)
    Explanation
    The correct answer is Tear Drop Cell (Dacryocyte). This is because the arrow in the diagram is pointing towards a cell that has a distinct teardrop shape. Dacryocytes are abnormally shaped red blood cells that can be seen in certain conditions such as myelofibrosis or thalassemia. They are characterized by their elongated shape with a pointed end, resembling a tear drop.

      Normal RBC

    • B.

      Lymphocyte

    • C.

      Nucleated RBC

    • D.

      Pappenheimer Bodies

    Correct Answer
    C. Nucleated RBC
    Explanation
    The cell identified by the arrow is a nucleated red blood cell. Nucleated red blood cells are immature red blood cells that still have a nucleus. In normal circumstances, red blood cells lose their nucleus during maturation in the bone marrow. However, in certain conditions such as severe anemia or bone marrow disorders, nucleated red blood cells may be present in the peripheral blood. This can be identified by the presence of a nucleus within the cell, as seen in the image.

    • A.

      Platelet, normal

    • B.

      Platelet, Giant

    • C.

      Cellular Debris

    • D.

      NRBC

    Correct Answer
    A. Platelet, normal
    Explanation
    The cell identified by the arrow is a normal platelet. This can be determined by comparing it to the other options listed. The platelet appears as a small, round cell with a granular appearance. The presence of granules is characteristic of platelets, while the other options do not exhibit this feature. Additionally, the size and shape of the cell match that of a normal platelet. Therefore, the correct answer is Platelet, normal.

    Identify the cell by the arrow.

    • A.

      Microcyte

    • B.

      Normal RBC

    • C.

      Spherocyte

    • D.

      Target Cell (Codocyte)

    Correct Answer
    B. Normal RBC
    Explanation
    The correct answer is "Normal RBC" because the arrow is pointing to a cell that appears to have a normal shape and size. Microcytes are smaller than normal RBCs, spherocytes have a spherical shape, and target cells have a characteristic target-like appearance. Since none of these characteristics are present in the cell indicated by the arrow, it can be identified as a normal RBC.

  • 13. 

    Identify the cell by the arrow.

    • A.

      Malarial Parasite

    • B.

      Normal Platelet

    • C.

      Giant Platelet

    Correct Answer
    C. Giant Platelet
    Explanation
    The cell identified by the arrow is a giant platelet. This can be determined by comparing it to the other options provided - malarial parasite and normal platelet. The giant platelet appears larger and more irregular in shape compared to the other two options, indicating that it is the correct answer.

    The RBC found in below illustration are the result of:

    • A.

      Rouleux formation

    • B.

      Micro agglutination

    • C.

      Over drying of blood smear

    • D.

      Cold agglutinin

    Correct Answer
    A. Rouleux formation
    Explanation
    Rouleaux formation refers to the stacking of red blood cells (RBCs) in a linear or coin-like fashion, resembling a stack of coins. This can occur due to various factors such as increased plasma proteins, changes in the surface charge of RBCs, or alterations in the shape of RBCs. Rouleaux formation is a reversible process and can be observed in conditions like inflammation, infections, or certain diseases. In this case, the RBCs seen in the illustration are the result of rouleaux formation, where the RBCs are stacked together, forming a chain-like structure.
