Systems and Models in Flower Anatomy

Click on the flashcard to see the answer



What is the function of the anther in a flower?

The anther produces and stores pollen grains.

How does the filament contribute to pollination?

The filament positions the anther for effective pollination.

What role does the stigma play in flower anatomy?

The stigma captures pollen grains.

How does the style aid in the fertilization process?

The style connects the stigma to the ovary and aids pollen tube growth.

What happens to the ovary after fertilization?

The ovary houses ovules and develops into fruit after fertilization.

Why are petals important for a flower?

Petals attract pollinators with their color and scent.

What is the function of sepals in a flower?

Sepals protect the flower bud before blooming.

Describe the relationship between the style and ovary.

The style connects the stigma to the ovary and allows the pollen tube to grow down to the ovary for fertilization.

What happens to the flower parts after fertilization?

After fertilization, the petals, sepals, stamens, style, and stigma may shrivel and fall off.

What transforms from an ovule after fertilization?

The ovule develops into a seed after fertilization.

How does the ovary of a flower change post-fertilization?

Post-fertilization, the ovary becomes a fruit.

What are the two main reproductive structures of a flower?

The pistil (female organ) and stamen (male organ).

Explain the difference between self-pollination and cross-pollination.

Self-pollination occurs within the same flower, while cross-pollination involves pollen transfer between different plants.

Why might cross-pollination be advantageous over self-pollination?

Cross-pollination introduces greater genetic diversity.

What results from the fusion of male and female gametes in a flower?

The fusion results in a zygote, which eventually develops into an embryo.
