Worked Solution & Example Answer:(i) Draw a large labelled diagram to show the internal structure of a flower - Leaving Cert Biology - Question a - 2011
Step 1
Draw a large labelled diagram to show the internal structure of a flower.
Answer
To illustrate the internal structure of a flower, create a detailed diagram that includes at least three of the following components: sepals, petals, stamens, and carpels. Each part should be clearly labeled for full clarity and understanding.
- Sepals: Protective outer parts of the flower.
- Petals: Often brightly colored to attract pollinators.
- Stamens: The male reproductive part, which includes the anther and filament.
- Carpel: The female reproductive part, consisting of the ovary, style, and stigma.
Step 2
Give two ways by which pollen is transferred from one flower to another.
Answer
Pollen can be transferred from one flower to another through several mechanisms, including:
- Wind: Pollen is carried from one flower to another by the wind, which helps in cross-pollination.
- Insects: Bees and other pollinators collect pollen and transfer it while visiting different flowers.

Step 5
Name any two methods of artificially propagating plants.
Answer
Two commonly used methods of artificially propagating plants are:
- Grafting: A technique where tissues from one plant are joined with those of another plant to continue their growth together.
- Cutting: This involves taking a part of a plant, such as a stem or leaf, and encouraging it to grow roots to form a new plant.
