Q What is life cycle?A: The life cycle of an animal refers to the stages of development from an egg to an adult

which reproduce.

Page 3: Parts of flower

Q How life goes on?A: Life cycle goes on as life cycle repeat itself.

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.

Page 7: Parts of flower

Q What is petal?A: A petal is a flower which surrounds the reproductive organs

(stamen and carpel) of the flower.

Page 8: Parts of flower

Q Why are petal bright coloured and scented?A: Petals are often brightly coloured and scented to attract insects.

Page 9: Parts of flower

Q Where are the female cells and male cells found in the plant?

Parts Found at Name of cell

Male sex cell Anther Pollen grains

Female sex cell Ovary Ovules

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

Q What is filament?A: A filament is the stalk of the stamen which supports the anther.

Page 16: Parts of flower

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

Page 17: Parts of flower

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

Name organs of carpel.A: Typically each carpel has a stigma, style and ovary.

Page 21: Parts of flower

Q What is the stigma?A: The stigma is the uppermost part of the carpel. Pollen lands on

stigma.

Page 22: Parts of flower

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

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

Q What is the function of style?A: The pollen tube grows through the style after pollination.

Page 25: Parts of flower

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

Q What is an ovule?A: An ovule is a female sex cell.

Page 27: Parts of flower

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.
