Pollen Tube: The pollen tube is a long, slender tube that develops from a pollen grain. It grows down through the style and delivers the male sex cells (sperm) to the ovule for fertilization.
Anther: The anther is the part of the stamen, which is the male reproductive organ of the flower, where pollen grains are produced. The anther consists of pollen sacs that contain pollen grains.
Filament: The filament is a stalk-like structure that supports the anther. It holds the anther up so that it is properly positioned for pollination.
Stamen: The stamen is the male reproductive part of a flower, consisting of the anther and filament. It produces the male gametes (sperm) in the form of pollen grains.
Petal: Petals are brightly colored, often scented structures that attract animals such as insects and birds to the flower. They contain pigments that allow them to display a wide range of colors and patterns.
Ovule: The ovule is a structure located within the ovary of the flower. It contains the female reproductive cells, known as the egg cells or ovum. After fertilization, the ovule develops into a seed.
Receptacle: The receptacle is the swollen base of the flower where all the floral parts are attached. It provides support and serves as a point of attachment for the various parts of the flower.
Sepal: Sepals are the outermost, usually green, leaf-like structures in a flower. They protect the developing flower bud and support the flower when it is fully open. Sepals usually occur in sets and are collectively known as the calyx.
Pedicel: The pedicel is the stalk that connects the flower to the main stem or branch. It supports the flower and allows it to be positioned for maximum exposure to pollinators.
Stigma: The stigma is the sticky top part of the pistil, the female reproductive organ of the flower. It is responsible for capturing pollen grains during pollination.
Style: The style is a slender stalk that connects the stigma and the ovary. It allows the pollen tube to grow down into the ovary and deliver the male sex cells to the ovule.
Ovary: The ovary is the swollen base of the pistil that contains one or more ovules. It is the female reproductive structure of the flower and develops into the fruit after fertilization.
Pistil: The pistil is the female reproductive organ of the flower, consisting of the stigma, style, and ovary. It produces the female gametes (egg cells) and receives and supports the pollen for fertilization.
Explain the function of each part of the flower
Pollen Tube:
Anther: part of the stamen where pollen is made
Filament: a stalk, found in the stamen, that supports the anther
Stamen: the male part of a flower
Petal: attracts animals such as insects and birds by chemicals that people and other animals can smell.
Ovule:
Receptacle:
Sepal: protect the developing flower, and support it when it is open.
Pedicel:
Stigma: sticky top part of the pistil that captures pollen
Style: slender stalk that connects the stigma and ovary
Ovary: swollen base of the stigma that contains the female sex cells
Pistil: the female part of a flower
