What is the inflorescence meristem?
The inflorescence meristem produce small leaves before it next produces floral meristems. It is the floral meristem from which the flower develops.
In which inflorescence apical meristem terminates into flower?
In sympodial species, which produce inflorescence structures known as cymes, the apical meristem terminates in the floral meristem, while the lateral meristem becomes an inflorescence meristem.
What are the characteristics of inflorescence?
Inflorescences are described by many different characteristics including how the flowers are arranged on the peduncle, the blooming order of the flowers and how different clusters of flowers are grouped within it. These terms are general representations as plants in nature can have a combination of types.
What type of inflorescence is a Snapdragon?
In a raceme a flower develops at the upper angle (axil) between the stem and branch of each leaf along a long, unbranched axis. Each flower is borne on a short stalk, called a pedicel. An example of a raceme is found in the snapdragon (Antirrhinum majus).
What are meristem-identity genes?
The Arabidopsis floral meristem-identity genes APETALA1 (AP1) and LEAFY (LFY) confer floral identity on developing floral primordia, whereas TERMINAL FLOWER (TFL) is required to repress their expression within shoot and inflorescence meristems.
What is the function of floral meristem-identity genes?
THE Arabidopsis floral meristem-identity genes APETALA1 (API) and LEAFY (LFY) confer floral identity on developing floral primordia1–4, whereas TERMINAL FLOWER (TFL) is required to repress their expression within shoot and inflorescence meristems1,5.
What are meristem identity genes?
What is indefinite inflorescence?
racemose inflorescence (indefinite inflorescence) A type of flowering shoot (seeinflorescence) in which the growing region at the tip of the flower stalk continues to produce new flower buds during growth. As a result, the youngest flowers are at the top and the oldest flowers are at the base of the stalk.
What is inflorescence describe its types?
As defined by a botanical dictionary, an inflorescence is a cluster of flowers arranged along a floral axis. Inflorescences come in two types: Racemose and Cymose.
Which of the following are characteristics of racemose inflorescence?
Characteristic feature of Racemose Inflorescence: Peduncle is monopodial in nature. Flowers grouping is less common. Flowers are born laterally in acropetal succession, older flowers are at the periphery and younger ones are at the top. Fruits which are newly formed are not protected by flowers.
How do you identify a snapdragon?
Flowers, in elongated spikes, are each 3 to 4.5cm long with two lips that open when the sides of the flower are compressed – hence the dragon’s mouth implication in the common name. Most wild plants have pinkish purple flowers with yellow-and-white areas where the two lips touch.
What type of inflorescence is Gumamela?
b) Inflorescence: In Hibiscus rosa-sinensis, the inflorescence is a single flower. The inflorescence axis develops in the axil of a leaf and bears a single terminal flower (Fig….
