Detailed explanation-1: -Flowering plants reproduce sexually through a process called pollination. Flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. Pollen contains the male gametes.

Detailed explanation-2: -As a plant’s reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19). The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament.

Detailed explanation-3: -In flowering plants, male and female reproductive structures can be found in the same individual plant. The organ of sexual reproduction is the flower. Male gametes are found in pollen grains and produced in the anthers of the flower. Female gametes are found in ovules and produced in the ovary of the flower.

Detailed explanation-4: -Bisexual flowers: Flowers which contain both the stamens and the pistil are known as bisexual flowers. For example-Rose, Hibiscus, Gulmohar, Mustard etc. Uni-sexual flowers: The flowers which contain either the stamens or the pistil are known as unisexual flowers. For example-Maize, Papaya, Cucumber etc.

Detailed explanation-5: -Sexual reproduction involves the fusion of male and female gametes. In vegetative propagation new plants are produced from different vegetative parts such as leaves, stems and roots. Flower is the reproductive part of a plant. A flower may be unisexual with either the male or the female reproductive parts.
