How many plants and flowers can be determined as being either "male" or "female"?

I understand that pollen must reach the stigma of the pistol? of the flower in order to produce seed bearing fruit, but are all flowers , for example asexual or are there specifically male and female ones?





Please give some examples.








Thanks for your answers!

FlowersBirthday FlowersSympathy FlowersFlowers with functional stigma, style and ovary (gynoecium) are female. Flowers with functional stamens (androecium) are male.


Flowers with both are perfect; flowers with androecium only or gynoecium only are imperfect; flowers lacking either are sterile. and relatively rare.





Many flowering plants have perfect flowers; few have sterile flowers. The rest have imperfect or mixtures of perfect, imperfect and sterile flowers.





Vocabulary for you to look up: monoecious, dioecious, trioecious, monoclinous, diclinous, synoecious. Check the pronounciations, too... the %26quot;oecious%26quot; parts are derived from the Greek word for %26quot;household%26quot;, and that oe is more of a long E, not two vowel sounds.





nb: the plant part is a pistil, not pistol -- same root as pestle.
Reply:Some flowers are %26quot;perfect%26quot;, having both male and female sexual organs on the same flower. MOST flowers are %26quot;perfect%26quot;...dandelions, lilies, tomatoes, and roses, but the list also includes virtually every fruit and vegetable plant commonly found in North America.





Imperfect flowers have male and female organs on entirely separate flowers.





There are two kinds. Monoecious plants have both male and female blooms on one plant. Two examples of monoecious plants are the corn plant and the pecan tree.





Dioecious means each PLANT is entire male, or entirely female. You need one of each sex planted near each other to get these plants to reproduce. Some examples of dioecious plants are the holly bush, winterberries and and pistachio tree. In this instance, there has to be a lot of intervention by outside forces, such as insects, in order to pollinate the female flowers.
Reply:Most plants have both male %26amp; female parts on their flowers. Exceptions to this include holly, yew and ginko (maiden hair) trees. That is why not all holly trees etc have berries on them, only the female ones.
