Flower Dissection & Pollination

Flower Dissection & Pollination 3D is a virtual botany lab covering angiosperm anatomy, insect pollination, double fertilisation, and fruit development. Students can click or drag any organ across the four floral whorls: green sepals (calyx), pink petals (corolla), pollen-bearing stamens (filament and anther), and the cutaway central carpel/pistil showing the stigma, style, ovary, and ovule. Dragging the golden pollinator bee from an anther to the stigma germinates a glowing pollen tube that carries sperm nuclei down the style into the ovule, followed by ovary swelling into a mature fruit pericarp.

• Slide Dissection explode view to 100% to separate the sepals, petals, stamens, and central carpel radially for clear anatomical inspection.
• Click each floral part—Sepal, Petal, Stamen Anther, Stigma, Style, Ovary, and Ovule—to read its organ function and reproductive whorl.
• Drag the golden Pollinator Bee orb onto the central Stigma tip and watch the glowing sperm nucleus travel down the pollen tube into the ovule.
• Advance the Fruit development stage slider to watch the petals wither while the ovary wall swells into a protective fruit around the seed.

1. 1Identify the four concentric whorls of a complete angiosperm flower: calyx, corolla, androecium, and gynoecium.
2. 2Distinguish between pollination (pollen transfer from anther to stigma) and fertilisation (fusion of gametes inside the ovule).
3. 3Describe how a pollen grain germinates on the stigma and grows a pollen tube down the style to the ovule micropyle.
4. 4Explain how the fertilised ovule develops into a seed while the surrounding ovary matures into a fruit.
