Sexual Reproduction:

     Like other plants, the phalanopsis orchid exhibits alteration of generations. The reproductive structures are housed in the column of the flower. Pollination is done through insects. The bright colors and ornate labellum of the Phalaenopsis sago lisa attract pollinators. Certain orchids have developed close interaction with specific pollinator base on the coloration patterns of the flower. The six pictures below show step by step how orchids are pollinated. The green stick represents the insect pollinator. First the pollinator lands on the labellum of the flower. As the insects collects nectar, a adhesive pad that is connected to the pollinia attaches the insect. The insect than flies off with the pollinia to another flower. The pollinia is then “hooked” by the column when the insect flies off. The pollen from the pollinia then comes into contact with the stigmatic surface and is carried to the ovary where fertilization occurs. Thousands of tiny seed are produced in the three carpals of the ovary. Of the many seed dispersed into the wind few seeds will survive to germination
     Many orchid flower have developed close relationships with distinct pollinator. For example the color pattern on the labellum may resemble the mate of the pollinator. Other orchid labellums mimic the shape of the pollinator’s mate.

Asexual reproduction:

     Phalaenopsis orchids go through asexual reproduction in two way. One is by self-pollination. This is the same process as sexual reproduction except it is pollinated by pollen from itself, not another individual. Often the seedlings from this plant are weaker and show more abnormalities. The other means of asexual reproduction occurs when a plantlet or keiki begins to sprout of the parent plant. This happens only on certain areas of the plant and under certain conditions. These areas include the nodes on the spike, the roots and from the stem (below). Orchids are able to do this because plant cell are totipotent, meaning a cell can differentiate into any type of cell. Once the keiki has grown large enough it may fall off the parent plant or be removed for cultivation. This process of propagation is important to many growers.
