Pfr promotes flowering in long day plants and inhibits flowering in short-day plants. Therfore, during long dark periods (autumn-winter) short day plants will flower as most of the Pfr has been converted back into Pr in the morning. On the other hand, long-day plants flower in the shorter...

6. Produces new genotype & has important role in evolution. Disadvantages of Cross-Pollination: 1. It is a highly wasteful method as plants have to produce large number of pollen-grains since much of it may not reach the stigma of the right flower and get lost during transit. ...
There is a certain irony in all this talk of day length in promoting flowering, which is that the plant is not actually responsive to the day length at all, but rather to the length of the dark period. In order for obligate short-day flowering plants to begin flowering, they must experi...
However, this is not the case in many other kinds of animal (see pages xxx-xxx) and it is rarely the case in flowering plants. Just which sex are you? In some animal species, a single organism has both egg-producing and sperm-producing organs. These organisms are termed hermaphrodites ...
This is referred to as apogamy. Then, there is also an instance wherein their sporophyte may give rise to a gametophyte-looking offspring but with a ploidy level of a sporophyte. This, in turn, is called apospory. (Ref. 6) In flowering plants, the seed production from unfertilized ovules...
