Q Name the reproductive parts of a flowering plant.A: Female parts: a) stigma b) style c) ovary d) ovule(also called carpel or pistil)
Male parts: a) Anther b) filament (stalk) (also called stamen)
(The flower of a tomato plant has both male and female parts. Papaya plant has the male and female parts in separate flowers)

Q What is the sepal?A: The sepal is a leaf that protects a flower as a bud. When the flower
opens, the sepals may fall off or remain as a ring underneath the petals.

Q What is petal?A: A petal is a flower which surrounds the reproductive organs
(stamen and carpel) of the flower.

Q What is nectary?A: nectary is an area of cells at the base of the petals which can secrete a sweet sugary
liquid called nectar, which attracts insects for pollination.

Q What is stamen?A: A stamen is the male reproductive part of flower.
![Page 15: Parts of flower](https://reader036.vdocument.in/reader036/viewer/2022062323/56815ea2550346895dcd2fc3/html5/thumbnails/15.jpg)
Q What is filament?A: A filament is the stalk of the stamen which supports the anther.

Q What is anther?A: It is a part of stamen that produces pollen.

Q What is pollen?A: Pollen is the yellow dust-like grains which contain the male sex
cells of the plant.

Q What is a carpel or pistil?A: A carpel is the female reproductive organ of flower.
![Page 20: Parts of flower](https://reader036.vdocument.in/reader036/viewer/2022062323/56815ea2550346895dcd2fc3/html5/thumbnails/20.jpg)
Name organs of carpel.A: Typically each carpel has a stigma, style and ovary.

Q What is the stigma?A: The stigma is the uppermost part of the carpel. Pollen lands on
stigma.
![Page 22: Parts of flower](https://reader036.vdocument.in/reader036/viewer/2022062323/56815ea2550346895dcd2fc3/html5/thumbnails/22.jpg)
Q What is the function of the stigma?A: It secretes a sticky substance so that pollen lands on it.
![Page 23: Parts of flower](https://reader036.vdocument.in/reader036/viewer/2022062323/56815ea2550346895dcd2fc3/html5/thumbnails/23.jpg)
Q What is the style?A: The style is the part of the carpel between the stigma and the
ovary. It holds the stigma of a flower.
![Page 24: Parts of flower](https://reader036.vdocument.in/reader036/viewer/2022062323/56815ea2550346895dcd2fc3/html5/thumbnails/24.jpg)
Q What is the function of style?A: The pollen tube grows through the style after pollination.

Q What is ovary?A: The ovary is the part of flower that become a fruit and contain
one or more seeds (ovules).
![Page 26: Parts of flower](https://reader036.vdocument.in/reader036/viewer/2022062323/56815ea2550346895dcd2fc3/html5/thumbnails/26.jpg)
Q What is an ovule?A: An ovule is a female sex cell.
![Page 27: Parts of flower](https://reader036.vdocument.in/reader036/viewer/2022062323/56815ea2550346895dcd2fc3/html5/thumbnails/27.jpg)
Q What is the function of ovule?A: The ovule is attached to part of the ovary wall. After fertlisation it
develops into the seed.
