diagrams of reproductive systems

1. write the path/journey of sperm to egg to baby.

sc.912.l.14.7 relate the structure of each of the major plant organs and tissues to physiological processes

1. match the part of the flower to its description and label the diagram

______ anther a. a small leaf that protects the flower before it blooms
______ filament b. they contain pollen
______ ovary c. the sticky top of the pistil
______ petal d. the male part of the flower
______ pistil e. the part of the pistil between the stigma and the ovary
______ sepal g. the female part of the flower
______ style h. a part of the pistil that contains the egg cells and develop into seeds
______ stamen i. a part of the plant that attracts insects
______ stigma j. a stalk that supports the anther

Explanation:

For question 54, we match each flower part to its description:

• Anther: Contains pollen (B), as anthers produce and hold pollen.
• Filament: Stalk supporting anther (J), it's the structure that holds the anther.
• Ovary: Part of pistil with egg cells (H), ovaries contain ovules (egg cells) that develop into seeds.
• Petal: Attracts insects (I), petals are often colorful to draw pollinators.
• Pistil: Female part of flower (G), pistil is the female reproductive structure.
• Sepal: Protects flower before blooming (A), sepals are leaf - like and shield the bud.
• Style: Part of pistil between stigma and ovary (E), it's the tube - like structure in the pistil.
• Stamen: Male part of flower (D), stamen consists of anther and filament, the male reproductive part.
• Stigma: Sticky top of pistil (C), stigma is sticky to catch pollen.

Answer:

Anther - B
Filament - J
Ovary - H
Petal - I
Pistil - G
Sepal - A
Style - E
Stamen - D
Stigma - C
