Pollination is vital for the lifecycle of flowering plants because they are physically unable to mate. When animals or insects carry pollen from one plant to another, they help the plant sexually reproduce by bringing sperm producing cells (pollen) and eggs together. What are the most common pol...
Pollinationis essential to the perpetuation of thevastmajority of the world’s wild plants—and thus the perpetuation of nearly all terrestrialecosystems—as well as to the production of most of the fruit and seed crops that feed humanity. The importance of this seemingly simple movement of sperm...

Though this wide range of studies results in some isolation of specialties within zoology, theconceptualintegrationin the contemporary study of living things that has occurred in recent years emphasizes the structural and functional unity of life rather than...
Plant reproduction is the process by which plants generate new individuals, or offspring. Reproduction is either sexual or asexual. Sexual reproduction is the formation of offspring by the fusion ofgametes. Asexual reproduction is the formation of offspring without the fusion of gametes. Sexual reprodu...
Many, but not all hermaphroditic, bisexual flowers are self-pollinating, but others require cross-pollination from hermaphroditic flowers on other plants.

Gregor Mendel was an Augustinian monk who lived during the 19th century in the Austro-Hungarian empire. After completing his university studies, Mendel decided to conduct experiments in the cross-pollination of garden peas. For his studies, Mendel picked seven specific traits: ...
Pollination, which is the process of transferring the pollen to the stigma, can occur in two ways. It can be either through self-pollination or cross-pollination. In this way, the male gametes are transferred to the stigma of the flower, from where they reach the ovary. ...
When we discuss sexual reproduction in plants, we come across 3 major ways that it could possibly happen;“allogamy”, “autogamy”and “geitonogamy”. Allogamy Allogamyis the“cross-pollination phenomenon”where pollen’s spermatozoa from a plant’s flower fertilize the ovum of a different...
A pollen grain is a small collection of microspores that aid in fertilization and sexual reproduction in plants. It is attached to the anther of the male reproductive organ of the plant. Through self-pollination or by cross-polination through the assistance of pollinators, the pollen grains are...
Bombus lapidarius, known as the red-tailed bumblebee, is a species found in many parts of Europe. It is known for its black and red colors and is important for pollination. Their hives usually consist of only a few hundred bees and do not form complex colonies. Their males secrete more...
