INTRODUCTION:-
GYNOECIUM :-
Gynosium is the female reproductive part of the flower and is made of one more carpels.
A carpel consist of three parts namely stigma style and ovary.
Ovary is the enlarged basal part , on which lies the elongated tube, the style .
The style connects the ovary to the stigma.
Stigma is the usually tip of the style and is the receptive surface for pollen grains .
Each ovary bears one or more ovules attached to a flattened, cushion like placenta.
When more than one carpel is present , there may be free as in Lotus and rose and are called Apocarpous.
They are termed as Syncarpous when carpels are fused as in mustard and tomato.
After fertilisation , the ovules develop into seeds and the ovary matures into a fruit.
Androecium is composed of stamens.Each stamens which represents the male reproductive organ consists of a stalk or a filament and an anther.
Each anther is usually bilobed and each lobe has two chambers , the pollen sacs. The pollen grains are produced in pollen-sacs.A sterile stamen is staminode .
Stamens of flower may be united with other members such as petals or among themselves .
When stamens are attached to the petals , they are epipetalous as in brinjal
Epiphyllous when attached to the perianth as in the flower of Lily.
The stamens in a flower may either remain free ( polyandrous) or may be united in varying degrees .
The stamens may be united into bunch or one bundle ( monoadelphous) as in China rose or two bundles (diadelphous) as in pea , or into more than two bundles (polydelphous) as in citrus.
There may be variations in the length of filaments within a flower as in salvia and mustard.
