Detailed Solution

Assertion (A) is true. A flower is defined as modified shoot wherein the shoot apical meristem changes to floral meristem. The thalamus of a flower is the enlarged and condensed axis. It has nodes and very short internodes. It bears the floral whorls at the nodes. These whorls are arranged in a definite sequence. Hence, flower is called as modified shoot.

Reason (R) is true. Internode of the shoot gets condensed to produce different floral appendages laterally at successive nodes instead of leaves. A flower is a modified shoot wherein the shoot apical meristem changes to floral meristem. Internodes do not elongate and the axis gets condensed. The apex produces different kinds of floral appendages laterally at successive nodes instead of leaves.

Both assertion and reason are correct and reason is correct explanation for the assertion.
