REPRODUCTION IN FLOWERING PLANT

Flower and Structure of Anther

FLOWER STRUCTURE 

Flower is main reproductive organ of Plant.

Flowers are formed over mature plants in response to hormone induced structural and physiological changes in shoot apices . 

Shoot apices are transformed into an inflorescence over which floral primordia develop . 

The primordia grow into floral buds which undergo anthesis and form flowers . 

Typical flower has a broad base thalamus over

Part of flower

ACCESSORY OR NON ESSENTIAL FLORAL ORGAN 

- Sepals

- Petalals

ESSENTIAL FLORAL ORGAN 

- Stemens (androecium)

- Carpels (gynoecium)

Stamen - The male reproductive organ 

- Stamen is the male reproductive organ or microsporophyll of a flower . 

- It consists of two parts , filament and anther . 

- Filament is long and slender stalk . 

- It is attached proximally to thalamus , petal or tepal . 

- Distally it bears an anther . 

- Anther is broader knob like fertile part of the stamen .

Type of connection between anther and filament
