What are the reproductive parts of a flower
Answers
Answer:
Reproductive parts of the flower are the stamen (male, collectively termed the androecium) and carpel (often the carpel is referred to as the pistil, the female parts collectively termed the gynoecium).
Answer:
Flowers
Sexual reproduction is the sole function of flowers, often the showiest part of a plant. Flowers' beauty and fragrance evolved not to please humans but to attract pollinators (insects or birds), which are central to the reproductive process.
Flowers also help classify plants.
The system of plant nomenclature we use today was developed by Carl von Linné (Linnaeus) and is based on flowers, reproductive parts of plants or both. One reason his system is successful is that flowers are the plant part least influenced by environmental changes. Thus, a knowledge of flowers and their parts is essential for anyone interested in plant identification.
Structure
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. This filament holds the anther in position, making the pollen available for dispersal by wind, insects, or birds.
Petals generally are the highly colored portions of a flower.
The pistil is a plant's female part. It generally is shaped like a bowling pin and is located in the flower's center. It consists of a stigma, style and ovary. The stigma is located at the top and is connected by the style to the ovary. The ovary contains eggs, which reside in ovules. If an egg is fertilized, the ovule develops into a seed.
Sepals are small, green, leaflike structures located at the base of a flower. They protect the flower bud. Collectively, the sepals are called a calyx.
Petals generally are the highly colored portions of a flower. Like nectar glands, petals may contain perfume. Collectively, the petals are called a corolla. The number of petals on a flower often is used to help identify plant families and genera. Flowers of dicots typically have four or five sepals, petals or multiples thereof. In monocots, these floral parts typically come in threes or multiples of three.
