They are protandrous hermaphrodites, except for " Oikopleura dioica " which is gonochoric, and a larva resembles the tadpole larva of ascidians.
12.
The ( white and fragrant ) flowers are arranged in more-or-less drooping Protandrous, bisexual flowers and male flowers exist on the same individual tree.
13.
The flowers are protandrous : on the second night of blooming, the pollen is released, and the stigma develops to its final position by the third night.
14.
The pulverulent seeds are dispersed by the wind ( anemochory ) . " Trochodendron " is present in both protandrous and protogynous forms that are self-compatible.
15.
Colonies of " M . membranacea " are protandrous sequential hermaphrodites, where colonies transition from male to female reproductive stages, allowing fertilization to occur between colonies or within colonies.
16.
The primary mechanism used by flowering plants to ensure outcrossing involves a genetic mechanism known as protandrous ( with the anthers maturing first ) or protogynous ( with the carpels mature first ).
17.
It can build a cocoon, which allows it to avoid desiccation while being transported, and it may be able to build populations quickly in new areas as it is a protandrous hermaphrodite.
18.
Males fly more and are generally more active by spending most of their time locating mates . " Pyronia tithonus " is a protandrous species, meaning the males emerge before the females.
19.
Biology of this protandrous hermaphrodite is presumed to be similar to that of " Tenualosa ilisha ", but the fewer gill rakers suggest an intake of larger species of zooplankton as food.
20.
Firstly, they are protandrous : a flower's pollen is released around 72 hours before it becomes itself receptive to pollen, by which time around half of its pollen has lost its viability.
