Q. Why are flowing plants considered by many botanists to be the most successful land plants?
Answer to the student: The plants in which the sex organs are carried within the flowers and the seeds are enclosed in a fruit are called angiosperms. Angiosperms are commonly known as flowering plants. Many botanists considered the flowering plants are the most successful group of land plants. Flowering plant success is primarily attributed to their co-evolution with animals (Chae K, Lord EM, 2011). When spore-producing plants need on water for reproduction, while non-flowering seed plants need wind to carry pollen to a seed. There are some systems of nature it contains to success. Earliest developments that led to the

Flowers allow them to attract pollinators (bees, bats, moths, birds) and encourage/promote cross pollination, leading to genetic variation which contributes to the success of Angiosperms. Whereas Gymnosperms typically rely upon wind/water/chance to disperse their seeds. The development of flowers and fruit in angiosperms is another factor that gives flowering plants an advantage over mosses when living on land. Flowers are four sets of modified leaves: petals, stamens, sepals, and carpels (Julian C, Rodrigo J, Herrero M, 2011). These modified leaves cover the flower before it opens. The petals contain brightly colored and attract insects and other pollinators spread the sperm. Stamens are a common male reproductive organs in a flower, whereas the carpel houses the female reproductive organs. A stamen consists of a supportive filament, and an anther, where pollen is produced. A carpel houses the stigma, which opens into a tube called the style, which leads to the ovary of the plant. The evolution of flowers was an important step towards angiosperms being successful land because pollination by both wind and pollinators took advantage of terrestrial animals and wind patterns. When I go to the fruits it is a mature ovaries, which develop from fertilized ovules, which thicken and enlarge after fertilization. Fruits also protect dormant seeds within them, and aid in their dispersal. Modifications in fruits help to disperse
