Study Notes

Plant Diversity

Distinction between flowering (angiosperms) and non-flowering plants; flowering plants produce flowers, while non-flowering do not.
Examples of flowering plants include Rose, Gardenia, and Water Lily, whereas non-flowering plants include Ferns and Salvinia.
Androecium is the male part of a flower, consisting of stamens composed of an anther and a filament. Its primary role is pollen production.
Gynoecium is the female part of a flower, containing components such as the stigma, style, ovary, and ovules. Its main function is seed production.
Diversity of flowers:
- White flowers: Example - ‘Idda’/‘Oosi mallikai’
- Colorful petals: Example - Rose
- Night-blooming flowers: Example - ‘Sepalika’/‘Pavala mallikai’
- Fragrant flowers: Example - Jasmine
- Nectar-producing flowers: Example - ‘Kathurumurunga’/‘Agathi’
Fruits develop from flowers and contain seeds. Seeds germinate to produce new seedlings.
Compound leaves, such as those of Coconut and Tamarind, have multiple leaflets.
Photosynthesis is the primary function of leaves, allowing plants to produce food. Some leaves, like Aloe, are adapted for water storage.
Specific leaves, such as Bryophyllum, can reproduce vegetatively, producing new plants through leaf sections.
Flowers are vital for sexual reproduction, combining male and female structures to form seeds.
Flower morphology varies greatly in size, shape, color, and scent, which aids in plant reproduction.

Description

Explore the anatomy of flowers with a focus on the androecium, which encompasses the stamens. This quiz will test your knowledge about the components of the stamen, including the anther and filament, as well as their functions in pollen production.
