Answer 2

Undifferentiated CALYX and COROLLA are together called PERIANTH.

Explanation:

When the petals and sepals (calyx and corolla) of a flower are undifferentiated i.e., not separated and are undistinguishable that arrangement is called as PERIANTH. This is a non-reproductive part of the flower which forms an envelope around the sexual organs. The individual parts of PERIANTH is called as TEPALS.

PETALOID- non green perianth is called petaloid.

SEPALOID- green perianth is called as sepaloid perianth.
