Detailed Description

Bee bread or bee pollen is the main source of food for most honey bees and their larvae. It is fed to all larvae except those that are destined to become queens; the queen larvae are fed royal jelly instead. Bee bread consists of honey and pollens which are gathered by the worker bees. A recent study of bee bread showed it contain 188 kinds of fungi and 29 kinds of bacteria. Bee bread is sometimes referred to as ambrosia.Bee bread is used in naturopathic medicine traditions and as a nutritional supplement, although exposure may trigger allergic or anaphylactic reactions in sensitive people. Analysis of the distribution of pollen grains of various species contained in surface layer deposits, especially peat bogs and lake sediments, from which a record of past climate may be inferred. Because the lake sediments accumulate over time, a core of the mud will show that the mud at the bottom will be the oldest and the mud at the top will be the newest. By separating the samples of the core, we can get a record of how the vegetation around that site has changed. This has shown us that the area around the Great Lakes was tundra 11,000 years ago. For more details, please see the Palynology entry. In non-flowering seed plants, pollen germinates in the pollen chamber, located beneath and inside the micropyle. A pollen tube is produced, which grows into the nucellus to provide nutrients for the developing sperm cells. Sperm cells of Pinophyta and Gnetophyta are without flagella, and are carried by the pollen tube, while those of Cycadophyta and Ginkgophyta have many flagella. When placed on the stigma of a flowering plant, under favorable circumstances, a pollen grain puts forth a pollen tube which grows down the tissue of the style to the ovary, and makes its way along the placenta, guided by projections or hairs, to the micropyle of an ovule. The nucleus of the tube cell has meanwhile passed into the tube, as does also the generative nucleus which divides (if it hasn't already) to form two sperm cells. The sperm cells are carried to their destination in the tip of the pollen-tube.
