Vascular plants are defined as any plants that exhibit xylem and phloem, the vascular tissues. The vascular plants composed of all seed-bearing plants such as gymnosperm and angiosperm and the
Explanation of Solution
The wind-pollinated angiosperms usually have small flowers but have a large amount of pollen whereas, animal-pollinated angiosperm have larger flowers but less pollen.
The movement of a pollen grain from an animal-pollinated angiosperm is effective compared to the wind-pollinated conifer. This is because the wind-pollinated angiosperms (plants) can reproduce only if their populations are high in numbers. As no wind-carried pollen is probably to fall on isolated individuals, low population density species may go extinct.
On the other hand, since animal pollinators effectively search for rare species, they can persist at decreased population densities.

- If there is a steep decline in the population of the major pollinators in an area, which of the following angiosperms would be most directly affected: aspen trees, pear trees, or dandelion plants? Why?arrow_forwardSome angiosperm species have exclusive relationships with just one species of pollinator. How would this relationship benefit the plant? What are the risks to the plant?arrow_forwardin fruits of wild daisy, what role can the pappus play in seed dispersal?arrow_forward
- Pollen grains of water pollinated species have a special characteristics for protection from water. What is that?arrow_forwardMany flowers have both anthers and pistils. What prevents self-pollination and later self-fertilization?arrow_forwardWhat are the relationship of angiosperms and gymnosperms with pollinator species,? please cite at least 5 pollinators species (definition, example, and how they pollinate).arrow_forward
