Why do cells differentiate during development?

• A. To perform specialized functions necessary for the organism's survival
• B. To become more resistant to environmental changes
• C. To replicate their DNA more efficiently
• D. To increase their size and volume

Answer: (A)

Verified step by step guidance

1. Understand that cell differentiation is a process where a cell changes from one cell type to another, usually becoming more specialized.
2. Recognize that during development, organisms need a variety of cell types to perform different functions essential for survival, such as muscle cells for movement, nerve cells for signaling, and blood cells for transport.
3. Consider that specialized functions are necessary for the organism's survival because they allow the organism to perform complex tasks and maintain homeostasis.
4. Acknowledge that while differentiation does not directly make cells more resistant to environmental changes, it allows the organism as a whole to adapt and respond to its environment more effectively.
5. Conclude that the primary reason for cell differentiation during development is to perform specialized functions necessary for the organism's survival, rather than increasing size, volume, or DNA replication efficiency.
