Pollination differs between angiosperms and gymnosperms in that most angiosperms entice animals to carry their pollen from plant to plant, while most gymnosperms rely on the wind carrying their pollen to other plants. There are many wind-pollinated angiosperms and a very few animal-pollinated gymnosperms, however. The methods angiosperms use tend to be more effective at spreading quickly, but gymnosperms, particularly conifers, are generally better adapted to cold or dry environments.Continue Reading
According to Tulane University, gymnosperms were the first major group of plants to emerge after ferns and their allies, displacing that earlier group as the dominant land plants. Angiosperms arose relatively soon after, however, and quickly displaced the gymnosperms in turn. Their dominance was not as complete, however, since one group of gymnosperms, the conifers, still dominate in colder regions and at higher altitudes.
Angiosperms have more advanced tissues and much more diversity than modern gymnosperms, in large part due to their more effective methods of pollination. This is particularly true in areas where insect pollinators are plentiful. However, even with wind-pollinated species, such as grasses, their ability to grow quickly allows them to be the pioneer flora in many environments, starting environmental succession even where later stages are dominated by gymnosperms.Learn more about Botany
Pollination is the process whereby pollen grains move from the anther to the stigma on a flower’s style, while fertilization is the fusion of the male gametes and female egg cells to form a new plant seed. Pollination precedes fertilization and depends on such media as wind, water and insects. Pollination takes place externally, while fertilization occurs in the inside of the flower and does not depend on external vectors.Full Answer >
In wind-pollinated plants, the microsporangia is on the outside of the plant, so it can be blown off and be dispersed by the wind. Insect pollination, on the other hand, requires an insect to move the pollen from one place to another.Full Answer >
Vascular plants can be classified into two major types: gymnosperms or angiosperms. Gymnosperms are types of plants that reproduce by creating cones that contain their seeds. Angiosperms are types of vascular plants that create seeds in their fruits or flowers.Full Answer >
Wind pollination occurs when the pollen from flowers is transported by the wind. It is also known as anemophily, and it occurs every day to pollinate crops and trees.Full Answer >
