What is the function of the anther in a flower?
Click to flip
The anther produces and stores pollen grains.
Click to flip
How does the filament contribute to pollination?
Click to flip
The filament positions the anther for effective pollination.
Click to flip
What role does the stigma play in flower anatomy?
Click to flip
The stigma captures pollen grains.
Click to flip
How does the style aid in the fertilization process?
Click to flip
The style connects the stigma to the ovary and aids pollen tube growth.
Click to flip
What happens to the ovary after fertilization?
Click to flip
The ovary houses ovules and develops into fruit after fertilization.
Click to flip
Why are petals important for a flower?
Click to flip
Petals attract pollinators with their color and scent.
Click to flip
What is the function of sepals in a flower?
Click to flip
Sepals protect the flower bud before blooming.
Click to flip
Describe the relationship between the style and ovary.
Click to flip
The style connects the stigma to the ovary and allows the pollen tube to grow down to the ovary for fertilization.
Click to flip
What happens to the flower parts after fertilization?
Click to flip
After fertilization, the petals, sepals, stamens, style, and stigma may shrivel and fall off.
Click to flip
What transforms from an ovule after fertilization?
Click to flip
The ovule develops into a seed after fertilization.
Click to flip
How does the ovary of a flower change post-fertilization?
Click to flip
Post-fertilization, the ovary becomes a fruit.
Click to flip
What are the two main reproductive structures of a flower?
Click to flip
The pistil (female organ) and stamen (male organ).
Click to flip
Explain the difference between self-pollination and cross-pollination.
Click to flip
Self-pollination occurs within the same flower, while cross-pollination involves pollen transfer between different plants.
Click to flip
Why might cross-pollination be advantageous over self-pollination?
Click to flip
Cross-pollination introduces greater genetic diversity.
Click to flip
What results from the fusion of male and female gametes in a flower?
Click to flip
The fusion results in a zygote, which eventually develops into an embryo.
