Detailed explanation-1: -Flowers are how plants produce seeds to reproduce. In many cases, the flower contains male and female parts, roughly equivalent to the male and female sexes of animals.
Detailed explanation-2: -Flowers in plants carry out the reproductive functions of plants. Male and female gametes are fused to produce the seeds. These seeds bear the fruit which undergoes germination to produce new plant structures. This process of reproduction takes place in the reproductive parts of the flower.
Detailed explanation-3: -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-4: -Ovary – The lower, often times enlarged part of the pistil, which contains the egg cells and produces the seeds. The ovary becomes the fruit. Petals – Leaf-like, often colorful part of the plant that surrounds the reproductive parts of the flower and make the flower conspicuous to pollinators.
Detailed explanation-5: -The reproductive parts of the flower that are necessary for seed production are the stamen (the male organ) and carpel (the female organ). If a flower has both of these parts, it is called a perfect flower, even if it lacks some of the other key parts.
