Which cell has the shape of a biconcave disc?Multiple choice question.lymphoblastwhite blood cellred blood cellhemocytoblast

Break Down the Problem

1. Identify the characteristics of each cell type listed in the options.
2. Determine the correct answer based on the shape of the cells.

Relevant Concepts

• Red Blood Cells (RBCs): Characterized by a biconcave disc shape, which increases surface area for gas exchange.
• Lymphoblasts: Immature lymphocytes involved in the immune response, but not typically described with a biconcave shape.
• White Blood Cells: Have various shapes depending on their type (e.g., neutrophils, lymphocytes) but are not biconcave.
• Hemocytoblasts: Stem cells in the bone marrow that give rise to blood cells; they have a more rounded shape.

Analysis and Detail

1. Red Blood Cells: The primary function of red blood cells is to transport oxygen and carbon dioxide. Their biconcave shape allows for flexibility and maximizes surface area for gas exchange.
2. Lymphoblasts: These are progenitor cells, large and round, developing into lymphocytes that do not exhibit a biconcave form.
3. White Blood Cells: These cells, such as neutrophils and monocytes, can vary significantly in shape but do not share the biconcave disc characteristic.
4. Hemocytoblasts: These stem cells are typically more rounded as they are in the process of differentiating into various blood cells.

Verify and Summarize

After reviewing the characteristics of each answer choice, the cell type that is known for its biconcave disc shape is the red blood cell.

Final Answer

Red blood cell is the cell that has the shape of a biconcave disc.
