The function of the filament is simply to hold up the anther, extending it up to an accessible part of the flower for pollinators reach, or for the wind to disperse the pollen. Tissue is formed by groups of cells that are alike in activity and structure. (b) The fertile leaves become microsporophyll’s and megasporophylls, which bear anthers and ovules respectively. Students label the parts of a flower and fill in a parts and functions table. Except for the root cap, the other three zones are collectively known as the ‘region of root tip’. These different types are ray flowers and disk flowers. The pistil is the female structure of a flower, which mainly consists of stigma, style, ovary and ovule. Pistil – Central female organ of the flower. In Agave Americana some of the floral buds become modified into vegetative buds, called bulbils for vegetative propagation. The foliar nature of sepals and petals is evident from their similarity to leaves as regards structure form and venation, e.g., in Mussaenda one of the sepals becomes modified into a distinct cream coloured leaf.

The sepals and petals which constitute the calyx and corolla respectively are the sterile parts. The outermost wall layer of the anther is the epidermis. Incomplete flower C. Staminate flower D. Bracteate flower. In the simplest cases vascular traces for different organs and whorls of organs arise quite independently, (e.g., Aquilegia). Display the definitions on a word wall or an anchor chart: The sepals resemble leaves in their anatomy. A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms).The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs.
