About this book Introduction The study of the development of flowering plants may be said to be in the throes of a revolution. The ovary is unilocular. Petals attract pollinators to the flower. They are called rhizomes. There are four main flower parts in angiosperms : sepals, petals, stamens, and carpels.
The literature on the subject is extensive and continues to grow rapidly as new discoveries pile one on top of the other; moreover, these striking advances in our knowledge have put plant developmental biology well ahead of other aspects of the study of plants. The anther contains pollen sacs, in which meiosis occurs and pollen grains form. Inflorescence is the manner in which the flowers are arranged on the flowering axis. Flowers attract pollinators, and fruits encourage animals to disperse the seeds.
Floral Inhibitor Theory: In the yearsLona, Von Denffer and others postulated that plants grown in conditions un-favourable for flowering produce floral inhibitors. The fused anthers form a ring around the gynaecium, e. In alternate phyllotaxy, a single leaf arises from the node of a branch. These plants mature faster than and are sturdier than plants that develop from seeds. In hypogynous flowers, the ovary occupies the highest position on the thalamus while other floral parts are situated below it.

Superior and Inferior Ovaries: The ovary is termed superior when the other floral organs are not connected with it directly or indirectly. A swollen ovary wall forms flesh of the fruit.
In Salvia Fig. Parietal Fig. Cleland could identify the flower-inducing biology of flowering book as salicylic acid but failure to induce flower initiation with this chemical makes it unlikely that this compound is the floral hormone.
Dehiscence of Anthers: The lobes of an anther dehisce to expose the pollen grains by the following methods Fig. Such a claim has not been confirmed in subsequent biology of flowering book. When both the anther lobes are present, the stamen is called bithecous. Flowering Plants Angiosperms, or flowering seed plants, form seeds in ovaries.
Placentation: Placenta is a parenchymatous cushion present inside the ovary where ovules are borne. A long pollen tube grows from the pollen landing on the stigma down the style towards the ovule, which is located in the ovary.

Whereas considerations of developmental phenomena were at one time largely restricted to the structure and physiology of a wide selection of plants, recent molecular and genetic approaches are focused on one or two model systems. Theory 5. Parts of a Flower A flower consists of male and female reproductive structures.

The number of placentae correspond to the number of fusing carpels, e.
These results support the concept of a transmissible floral stimulus which seems to be physiologically similar in all photoperiodic plants.
In both cup-shaped and flask-shaped perigyny gynaecium or biology of flowering book is described as half inferior while androperianth or the remaining floral parts are said to be half superior.
When a single anther lobe is found, the stamen is termed as monothecous family Malvaceae, e. From these observations.Diversity and Evolutionary Biology of Tropical Flowers (Cambridge Tropical Biology Series) by Peter K.
