plant reproductive organ

• Receptacle


  The enlarged upper end of a flower stalk which bears the flower or group of flowers

  
• Sepals


  Modified leaves which enclose and protect the other parts of a flower when it is still a bud. When the flower blooms, the sepal supports the bottom of the flower
• Petals


  Form the most obvious part of a flower. Most petals are brightly colored to attract insects for pollination
• Stamen


  The male part of a flower. It consists of filament and the anther
• Filament


  Holds the anther in a position tall enough to release the pollen
• Anther


  Consists of two lobes that contain pollen sacs
• Pistil


  The female part of a flower. It consists of the stigma, style, and ovary

  
• Style


  A stalk that connects the stigma to the ovary. It is tall enough to trap pollen grains
• Stigma


  A swollen structure at the end of the style. It receives the pollen grains. The mature stigma secretes a fluid that stimulates the pollen grains to germinate
• Ovary


  Holds the egg cells which are to be fertilized by the sperm from the pollen grains
• Calyx


  A group of sepals
• Corolla


  A group of petals

  
• Pollen sacs


  Have pollen grains that are released by anther when they mature
• Types of Flowers


  • Complete flower
  • Incomplete flower
  • Perfect flower
  • Imperfect flower
• Complete flower


  Has a complete set of structures (receptacle, sepals, petals, stamen, and pistil)

  
• Incomplete flower


  Lacks one of the structures of a complete flower
• Perfect flower


  Has the male (stamen) and the female (pistil) reproductive parts

  
• Imperfect flower


  Only has either the pistil or the stamen alone
• Identify the complete parts of a flower

  • Receptacle
  • Sepals
  • Petals
  • Stamen
  • Pistil

  
• Plants can reproduce through their roots, stems, leaves, and flowers
• A complete flower has the following parts: receptacle, sepals, petals, stamens, and pistils
