Multiple Choice

Why are egg cells typically larger than sperm cells in the process of meiosis?

Sperm cells need to be small to carry more genetic material.

Egg cells are larger because they undergo more divisions during meiosis.

Egg cells contain more cytoplasm to support early development.

Sperm cells are small to increase their motility and speed.

Verified step by step guidance

Understand the roles of egg and sperm cells: Egg cells (ova) are designed to provide not only genetic material but also the necessary nutrients and organelles to support the early stages of embryonic development. Sperm cells, on the other hand, are primarily designed to deliver genetic material to the egg.

Consider the structure and function of egg cells: Egg cells are larger because they contain a significant amount of cytoplasm. This cytoplasm is rich in nutrients and organelles, which are crucial for the initial stages of development after fertilization.

Analyze the structure and function of sperm cells: Sperm cells are small and streamlined to enhance their motility. Their primary function is to reach and fertilize the egg, which requires them to be fast and efficient swimmers.

Examine the process of meiosis in egg and sperm cells: During meiosis, egg cells undergo asymmetric division, resulting in one large egg cell and smaller polar bodies that are typically reabsorbed. This ensures that the egg retains most of the cytoplasm.

Conclude why egg cells are larger: The larger size of egg cells is due to the need to support early embryonic development with ample cytoplasm, while sperm cells are optimized for mobility and speed to reach the egg for fertilization.
