(a) flowers are of various colours
(b) flowers can be safely pressed
(c) reproductive parts are more stable and
conservative than vegetative parts
(d) flowers are nice to work with

Answer 1

Floral features are used to identify because reproductive parts are more stable and conservative than vegetative parts.

• Option (c)
• The floral features can be relied upon, as they are more stable and conservative.

• Whereas, in the case of the vegetative parts,
• due to the environmental factors, the Vegetative parts exhibit changes quite readily and are relatively less stable.  

Answer 2

Floral features are chiefly used in Angiosperms  identification because

reproductive parts are more stable and conservative than vegetative parts.

option (D) is correct.

Explanation:

• Vegetative parts are relatively less stable and exhibit changes due to environmental factors quite readily.
• On the other hand, floral features are more conservative and can be relied upon.
• On the basis of reproductive parts of different flowers Linnaeus classified plants into different groups.

Thus Floral features are chiefly used in Angiosperms  identification because

reproductive parts are more stable and conservative than vegetative parts.
