  18. FUNCTIONS OF FLOWER STRUCTURES

  19. Functions of flower structures

  20. Sepal

  21. Sepals- protects the flower while it is a bud

  22. Petals

  23. Sepals- protects the flower while it is a bud • Petals- attract insects and animalsto aid in pollination

  24. Stamen A C B What’s that?

  25. Sepals- protects the flower while it is a bud • Petals- attract insects and animalsto aid in pollination • Stamens- male part of the flower which includes the anther and filament; it produces pollen.

  26. Anther

  27. Sepals- protects the flower while it is a bud • Petals- attract insects and animalsto aid in pollination • Stamens- male part of the flower which includes the anther and filament; it produces pollen. • Anther- produce and release pollen to the stigma of the same or another flower for reproduction.

  28. Anther Stamen Filament

  29. Anther- produce and release pollen to the stigma of the same or another flower for reproduction. • Filament-elevates the anther away from the flower for pollen dispersal and transports nutrients to the anther. • Pollen- contains sperm for fertilization.

  30. Pistil

  31. Anther- produce and release pollen to the stigma of the same or another flower for reproduction. • Filament-elevates the anther away from the flower for pollen dispersal and transports nutrients to the anther. • Pollen- contains sperm for fertilization. • Pistil (Carpel)-female part of the flower which includes the stigma, style and ovary; it produces ovules, which are similar to eggs in animals. Produces seeds and fruit.

  32. Stigma

  33. Anther- produce and release pollen to the stigma of the same or another flower for reproduction. • Filament-elevates the anther away from the flower for pollen dispersal and transports nutrients to the anther. • Pollen- contains sperm for fertilization. • Pistil (Carpel)-female part of the flower which includes the stigma, style and ovary; it produces ovules, which are similar to eggs in animals. Produces seeds and fruit. • Stigma- collects pollen on its surface and aids in fertilization

  35. Style Stigma Ovary

  36. Style Where is it located? What does it do? A B C

  37. Style Where is it located? What does it do? A Style C

  38. Pollen- contains sperm for fertilization. • Pistil (Carpel)-female part of the flower which includes the stigma, style and ovary; it produces ovules, which are similar to eggs in animals. Produces seeds and fruit. • Stigma- collects pollen on its surface and aids in fertilization • Style- elevates the stigma to collect pollen

  39. Ovary Where is it located? What does it do? A B C

  40. Ovary Where is it located? What does it do? A B Ovary

  41. Pollen- contains sperm for fertilization. • Pistil (Carpel)-female part of the flower which includes the stigma, style and ovary; it produces ovules, which are similar to eggs in animals. Produces seeds and fruit. • Stigma- collects pollen on its surface and aids in fertilization • Style- elevates the stigma to collect pollen • Ovary- produce ovules (eggs); when fertilized ovules become seeds and fruits.
