Lesson Worksheet: Sexual Reproduction in Flowering Plants Science
In this worksheet, we will practice identifying and describing the parts of a flowering plant that are involved in sexual reproduction.
Q1:
What structure within a flower is usually sticky to “catch” grains of pollen?
- APetals
- BAnther
- CSepal
- DStigma
- EStyle
Q2:
What is the main function of sepals?
- ATo produce male reproductive cells
- BTo attract pollinators to the plant
- CTo produce female reproductive cells
- DTo protect unopened buds
Q3:
Inside a flower, there are male and female reproductive parts. What name is given to the male reproductive organ?
- AStamen
- BStigma
- CStyle
- DCarpel
- EOvule
Q4:
Flowers contain the structures that help a plant reproduce sexually. Which part of the flower is usually brightly colored to attract insects to help pollinate the plant?
- AStamen
- BPetals
- CSepal
- DStigma
- EOvule
Q5:
Inside a flower, there are male and female reproductive parts. What name is given to the female reproductive organ?
- ASepal
- BCarpel
- CPetal
- DAnther
- EStamen
Q6:
What structure within a flower contains the ovules, the female reproductive cells?
- APetals
- BAnther
- CSepal
- DOvary
- EStyle
Q7:
Flowers can be divided into floral whorls. These are circular sections that each contain a different organ of the flower. The names of these whorls are shown in the diagram.
Which whorl contains the stamens?
- AAndroecium
- BCorolla
- CCalyx
- DGynoecium
Q8:
Which of the following tables correctly matches the reproductive parts of a flower to their functions?
- A
Part Anther Stigma Ovary Function Produces pollen that contain the male sex cells Contains one or more ovules, each containing a female sex cell “Catches” pollen grains - B
Part Anther Stigma Ovary Function Produces pollen that contain the male sex cells “Catches” pollen grains Contains one or more ovules, each containing a female sex cell - C
Part Anther Stigma Ovary Function “Catches” pollen grains Produces pollen that contain the male sex cells Contains one or more ovules, each containing a female sex cell - D
Part Anther Stigma Ovary Function Contains one or more ovules, each containing a female sex cell “Catches” pollen grains Produces pollen that contain the male sex cells
Q9:
Flowers can be divided into floral “whorls.” These are circular sections that each contain a different organ of the flower. The names of these whorls are shown in the diagram.
Which whorl contains the carpel?
- AAndroecium
- BCalyx
- CGynoecium
- DCorolla
Q10:
Flowers can be divided into floral whorls. These are circular sections that each contain a different organ of the flower. The names of these whorls are shown in the diagram.
Which whorl contains the sepals?
- ACalyx
- BCorolla
- CGynoecium
- DAndroecium
