Question

Flowers with irregular petals that could be divided into two similar halves by one plane only are called

Answer 1

Answer: Floral symmetry describes how a flower could be divided into two similar halves by one plane.

Step-by-step explanation:

• The petals of many flowers are irregular in size and shape.
• The floral formula, which takes into consideration certain floral features and components like — the number of sepals, petals, stamens, sizes etc., can be used to divide the symmetry of a flower into two or more identical images (mirror images).
• There may also be flowers without an axis of symmetry and those which cannot be divided into similar halves (or more) because of the way they are irregular is shape and size.
