.....................................................

takes place when one male gamete

Once the pollen reaches the

stigma, pollen tube traverses

down the ................... to the

ovary where fertilisation

occurs.

The ................................ is the base of

the flower to which other floral parts are

attached.

The .......................... are coloured to

attract the insects that carry the pollen.

Some flowers also produce ............... or

.............. that attracts insects.

The whorl ...................... is green that

protects the flower until it opens.​

Answer 1

The stigma collects the pollen grains.

The male whorl, called the stamen produces pollen grains .

The pollen grains represent the male reproductive system.

The ovary contains the egg or ovum.

Fertilisation takes place when one male gamete and the egg fuse together. The fertilised egg grows into seed from which the new plants can grow.

Pollination is the transfer of pollen grains from anther of the flower to the stigma of the same or a different flower.

Once the pollen reaches the stigma, pollen tube traverses down the style to the ovary where fertilisation occurs.

The pedicel/peduncle is the base of the flower to which other floral parts are attached.

The petals are coloured to attract the insects that carry the pollen.

Some flowers also produce sweet scents or bright colours that attracts insects.

The whorl sepal is green that protects the flower until it opens.​

Answer 2

Answer:

• Stigma

In the gynoecium of a flower, the stigma is the receptive tip of a carpel or of multiple fused carpels.

• Androecium, male gametes (pollen grains)

The flower's male reproductive whorl, or androecium, is where male gametes are produced. The androecium, which consists of an anther and a filament, is the stamen.

• Male gametophyte
• Embryo sac

The egg or ovum is housed in the embryo sac.

• Syngamy

One male gamete and the egg combine to fertilize the egg, which is known as syngamy.

• Geitonogamy

Geitonogamy refers to the movement of pollen grains from the anther of one flower to the stigma of another blossom on the same plant.

• Style

The pollen tube travels down the style to the ovary, where fertilization takes place, once it has reached the stigma.

• Thalamus

The thalamus, to which other floral components are linked, serves as the flower's basis.

• Petals

The petals are colored to draw the pollen-carrying insects. Additionally, some flowers have a delicious aroma or nectar that draws insects.

• Sweet odor, nectar

Additionally, some flowers have a delicious aroma or nectar that draws insects.

• Calyx

Before the flower opens, it is protected by a green whorl calyx.
