Accepted Answer

a-ix
The sepals are the parts of the flowers that are tiny green leaves that protect the flower bud. Together all the sepals are called the calyx.

b-viii
The flowers have colourful petals that help attract insects to facilitate pollination by honeybees, butterflies, etc.

c- i
Stamen is the male reproductive organ of the plant. It is made of two parts- a filament and an anther.

d-ii
Stamen is the male reproductive organ of a flower, typically consisting of a pollen-containing anther and a filament. Collectively the stamens form the androecium. The anther is the terminal part of a stamen usually consisting of two lobes each containing two sacs in which the pollen matures.

e- vii
The pistil is the female reproductive organ of a plant. It is a flask-shaped organ called a pistil that consists of three parts- stigma, style and ovary.

f- iii
The ovary is the female part of the flower, which is a swollen base of the pistil that contains eggs. The pollen tube grows to reach the ovary and the ovule.

g- x
The pollen grains which contain the male gametes stick to the hair of insects. When pollen grains fall on the stigma, it germinates and gives rise to a pollen tube that passes through the style and reaches the ovary of a pistil.

h-vi
A pistil consists of three parts, i.e., stigma, style and ovary. Style is a long, slender stalk that connects the stigma and the ovary. It acts a passageway through which the male gametes are transferred to the ovary by the formation of the pollen tube. The male gametes then fuse with the egg cell to form a zygote.

i-v
The gynoecium consists of (one or more) pistils. The pistil is the female reproductive part. A pistil is made of three parts, i.e., stigma, style and ovary. Stigmas are adapted to trap pollen with hairs with its sticky surface and to increase their efficiency of pollination.

j-iv
The stamen is made of two parts, i.e., a filament and an anther. The filament is a slender stick that supports the anther, which is where pollen develops. The function of the filament is simply to hold up the anther, extending it up to an accessible part of the flower for pollinators reach, or for the wind to disperse the pollen.
