(B) Polychasial
(C) Solitary
(D) Racemose​

Answer 1

option d is correct........

Answer 2

Answer:

The following points highlight the five major types of Inflorescence. The types are: 1. Solitary Flowers 2. Racemose Inflorescence 3. Cymose Inflorescence 4. Mixed Inflorescence 5. Special Inflorescence.

Type # 1. Solitary Flowers:

Flowers occur singly or are separated from other flowers of the same plant by vegetative regions. Solitary flowers are formed by direct transformation of shoot tips into flowers.

They are of two types:

Single flowers occur at the tips of the main stem and its branches, e.g., Poppy,

(ii) Solitary Axillary:

Single flowers occur in the axils of ordinary green or foliage leaves, e.g., Petunia, Garden Nasturtium, and Shoe Flower.

Type # 2. Racemose Inflorescence:

Racemose inflorescence is an indeterminate inflorescence which shows indefinite growth and bears a number of flowers due to the presence of active growing point. The arrangement of flowers is either acropetal (older towards base and younger towards apex) or centripetal (older towards periphery and younger towards centre). Racemose inflores­cence is of two types, simple and compound.

Simple Racemose Inflorescence (Fig 5.68):

ADVERTISEMENTS:

 

Simple racemose inflorescence is that indefinite inflorescence in which the peduncle is un-branched.

It is of the following types:

Simple Racemose Inflorescence

1. Typical Raceme:

An un-branched elongated peduncle bears stalked or pedicellate flowers in an acropetal fashion, e.g., Larkspur (Delphinium, Fig. 5.69 A), Lupin (Lupinus), Radish (Raphanus), Linaria.
