FLOWERS

 

FLOWERS ARE THE REPRODUCTIVE ORGANS OF A PLANT. TO ASSIST IN POSSIBLE REPRODUCTION FLOWERS ARE BRIGHTLY COLORED AND OFTEN PERFUMED TO ATTRACT AND ASSIST IN THEIR CHANCE TO REPRODUCE.

 

THE FLOWER STRUCTURE:

The main body of the flower is called the COROLLA. The corolla contains the PETALS, which surround the reproductive organs of the flower,

 

The male reproductive organs are called the STAMENS.

        At the end of each filament are the ANTHERS.

        Anthers hold the pollen.

        When the pollen had matured the anthers release it allowing the plant to reproduce.

 

The female reproductive organs are at the centre of the flower and are within the CARPEL.

The carpel has three parts:

        The expanded part at the bottom is the OVARY.

-The ovary holds the OVULES, which are the female eggs of the plant. When fertilisation occurs these eggs enlarge and swell becoming seeds.

        The STYLE is the central stalk of the carpel.

        At the end of the style are the STIGMA.

The stigma attract the pollen from the flowers male organs.

At the base of the flower are the SEPALS. These can be green in colour, and protect the flower when the flower is in bud.
