For plants, this relationship has resulted in more precise attraction of specific pollinators, facilitating the transfer of pollen to the stigmas of other plants and reducing the overall production of pollen. In contrast to anemophilous plants, which may produce around one million pollen grains per ovule, orchids typically produce a one-to-one ...
A good predictor for when a plant will bloom and produce pollen is a calculation of the growing degree days. The color of pollen below indicates the color as it appears when the pollen arrives at the beehive. After arriving to the colony with a fresh load of pollen, the honey bee unloads its pollen from the pollen basket located on its hind legs.

A pollinium (pl.: pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. [1] [2] This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen ...
The column both releases pollen and also receives it (from another individual) for fertilization. In the family Orchidaceae, unlike almost all other flowering plants , the single male anther at the tip of the column produces pollen that is not free and powdery but held in waxy masses of two, four or six pellets called pollinia .
In all the years of gardening endeavors, many of us have found pleasure in growing indoor plants. People like me choose the toughies of the houseplant world − Sanseveria, philodendrons, bird ...
