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.
Palynivore: eating pollen; Xylophage: eating wood; Algivore: eating algae (both macroalgae and microalgae) Phytoplanktonivore: eating phytoplankton; Omnivore: the eating of both plants, animals, fungi, bacteria etc. The term means "all-eater". By amount of meat in diet Hypercarnivore: more than 70% meat; Mesocarnivore: 30–70% meat
The term pollen source is often used in the context of beekeeping and refers to flowering plants as a source of pollen for bees or other insects. Bees collect pollen as a protein source to raise their brood. For the plant, the pollinizer, this can be an important mechanism for sexual reproduction, as the pollinator distributes its
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 ...
[10] (also called pollen vectors): organisms that carry or move the pollen grains from the anther of one flower to the receptive part of the carpel or pistil (stigma) of another. [11] Between 100,000 and 200,000 species of animal act as pollinators of the world's 250,000 species of flowering plant. [12]
The cell line for their product started with a fertilized egg from a Black Angus cow named Lucy living on a California farm. Producing meat this way could also dramatically reduce the impact of ...
More than 150 startups are chasing an ambitious goal: meat that doesn’t require raising and killing animals that is affordable and tastes and feels like the meat we eat now. Meat made from cells ...
Bee pollen, a natural substance collected by bees from the pollen of flowers, has long been used as a dietary supplement thanks to (disputed) claims that it has a variety of health benefits.
