- what are the cross floral diagrams of the hibiscus flower?What kind inflorescence does: -Mayana flower-Bataw flower-Caballero flower-Dendrobium flower have?Most of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.
- Name the smallest angiospermic flower.In some of the fruits, the floral parts are persistent even up to maturity. Identify these parts. Consider Psidium guajava and Oryza sativa. What are the structures attached at the upper part of the two fruits.What advantage does the hibiscus flower gain by clustering its stamens around the pistil?
