Describe the structure and function of reproductive organs in plants
Answers
The reproductive part of a plant is the flower.
The flower consists of a male reproductive as well as the female reproductive part.
The male reproductive part is the stamen which consists of a filament and the anther. The anther comprises the male gamete which is also known as pollen grain.
The female reproductive part consists of pistil,style,ovary and ovules . The ovules comprise the he female gametes.
Carpel : The female parts of a flower consist of an ovary, which contains one or more ovules, a style and the stigma. The ovary is at the base of the flower.
From the ovary, extends a tubular structure called the style and on the top of the style is a surface receptive to pollen called the stigma.
The stigma can take many different forms, most of them designed to help trap pollen. There are many variations on this basic structural theme.
After fertilization the ovule becomes the seed and the ovary becomes the fruit.
Stemen : he male parts of a flower consist of one or more stamens. Each stamen is made up of paired anthers (sacs containing pollen) on a filament or stalk.
The anthers are the orange/yellow structures often seen in the centre of a flower.
Pollen from the anthers of one flower is transferred to the stigma of another usually either by wind, or by animals, especially insects
The reproductive structures in higher plants are contained within flowers. Flowers have more than one petal, and the flower petals are collectively called the corolla. A flower bud is protected by green leafy structures called sepals. Collectively, all of the sepals form the calyx.
The corolla or petals are often brightly coloured with markings attractive to insects. The flowers may also be scented
