Honeybee with pollen baskets A pollen trap Fresh bee pollen Frozen bee pollen, a human food supplement Bee bread: the bee pollen stored in the combs Chunks of bee bread. Bee pollen, also known as bee bread and ambrosia, [1] is a ball or pellet of field-gathered flower pollen packed by worker honeybees, and used as the primary food source for the hive.
The worker bees in the colony mix dry pollen with nectar and/or honey with their enzymes, and naturally occurring yeast from the air. Workers then compact the pollen. storing each variety in an individual wax hexagonal cell , typically located within their bee brood nest. This creates a fermented pollen mix call beekeepers call 'bee bread'. Dry ...
The brood of Western honey bees develops within a bee hive. In man-made, removable frame hives, such as Langstroth hives, each frame which is mainly occupied by brood is called a brood frame. Brood frames usually have some pollen and nectar or honey in the upper corners of the frame. The rest of the brood frame cells may be empty or occupied by ...
Pollen itself is not the male gamete. [4] It is a gametophyte, something that could be considered an entire organism, which then produces the male gamete.Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive) cell.
Worker bees gather pollen in the pollen baskets on their back legs and carry it back to the hive where it is used as food for the developing brood. Pollen carried on their bodies may be transferred to another flower, where a small portion can rub off on the pistil, resulting in cross pollination.
The pollen enters a pollen chamber close to the nucellus, and there it may wait for a year before it germinates and forms a pollen tube that grows through the wall of the megasporangium (=nucellus) where fertilisation takes place. During this time, the megaspore mother cell divides by meiosis to form four haploid cells, three of which degenerate.
Sporopollenin is also found in the cell walls of several taxa of green alga, including Phycopeltis (an ulvophycean) [2] and Chlorella. [3] Spores are dispersed by many different environmental factors, such as wind, water or animals. In suitable conditions, the sporopollenin-rich walls of pollen grains and spores can persist in the fossil record ...
Pollen and nectar are placed in a cell, within which an egg is laid, and the cell is sealed until the adult bee emerges after pupation (mass provisioning). At any one time, hives can contain from 300 to more than 100,000 workers (with some authors claiming to calculate more than 150,000 workers, but with no methodology explanation), depending ...
