Question

Identify the correct sequence of regeneration process in Planaria.

• A. Growth of cells $\to$ Differentiation of cells $\to$ Organ development
• B. Differentiation of cells $\to$ Growth of cells $\to$ Formation of tissues
• C. Specialized cells proliferation $\to$ Formation of identical tissues $\to$ Organ formation
• D. Specialized cells proliferation $\to$ Differentiation of cells $\to$ Formation of new tissues

Answer 1

The correct option is C Specialized cells proliferation $\to$ Formation of identical tissues $\to$ Organ formation

The specialized cells present in the organism are known as stem cells which have the capacity of enormous multiplication and differentiation into various tissue types. Once the cells multiply and differentiate into the required tissue, they organize and form organs.
