Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. [2] In a case of self-pollination, this process takes place from the anther of a flower to the stigma of the same flower. [2] Pollen is infrequently used as food and food supplement. Because ...
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. It consists of simple sugars , protein , minerals and vitamins , fatty acids , and a small percentage of other components.
Ovules are fertilized in a process that starts with pollination, which is the movement of pollen from the stamens to the stigma-style-ovary system within the flower-head. After pollination, a pollen tube grows from the (deposited) pollen through the stigma down the style into the ovary to the ovule. Two sperm are transferred from the pollen to ...
A honeybee collecting pollen from a flower A pollen wasp (Jugurtia dispar), a type of wasp that exclusively feeds its larvae pollen. This is an example of a palynivore that is only a palynivore for part of its life span, as the adults of the species do not consume pollen
The pollen basket or corbicula (plural corbiculae) is part of the tibia on the hind legs of the female of certain species of bees. They use the structure in harvesting pollen and carrying it to the nest or hive where it is used as food by the colony. Bee species with no pollen baskets have scopae, which fulfil a similar role.
A food allergy is an abnormal immune response to food. The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, ...
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
Pollen tube elongation is an integral stage in the plant life cycle. The pollen tube acts as a conduit to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.
