Other characteristics of flowering Plants

Although flowers and also their contents are the significant innovations the angiosperms, they room not the only ones. Angiosperms likewise have an ext efficient vascular tissues. Additionally, in many flowering plants the ovaries ripen into fruits. Fruit are frequently brightly colored, so animals are most likely to see and eat them and disperse their seeds (see Figure below).

Brightly colored fruits attract animals that may disperse their seeds. It’s hard to miss the bright red apples on this trees.


Evolution of flowering Plants

Flowering plants are thought come have developed at least 200 million years earlier from gymnosperms prefer Gnetae. The earliest well-known fossils that flowering plants are about 125 million year old. The fossil flowers have actually male and female reproductive organs yet no petals or sepals.

Scientists think that the earliest flowers attracted insects and also other animals, which spread pollen indigenous flower come flower. This substantially increased the efficiency of fertilization over wind-spread pollen, which could or can not in reality land on another flower. Come take much better advantage that this “animal labor,” plants developed traits such as brightly colored petals to attract pollinators. In exchange because that pollination, flowers gave the pollinators nectar.

Giving complimentary nectar to any animal that occurred to come follow me was no an reliable use that resources. Much of the pollen could be carried to flower of different types and thus wasted. Together a result, many plants progressed ways to “hide” your nectar native all but very specific pollinators, which would certainly be an ext likely come visit just flowers of the same species. For your part, pet pollinators co-evolved properties that enabled them to acquire to the hidden nectar. Two instances of this form of co-evolution are presented in Figure below.

The hummingbird has actually a long narrow invoice to reach nectar at the bottom the the tube-shaped flowers. The bat is active at night, therefore bright white, night-blooming flowers attract it. In each case, the flower plant and also its pollinator co-evolved to become better suited because that their duties in the symugandan-news.comtic relationship.

Some the the most recent angiosperms to evolve are grasses. Humans started domesticating grasses such as wheat around 10,000 year ago. Why grasses? lock have numerous large, edible seed that save a most nutritious save food. They room also relatively easy come harvest. Due to the fact that then, humans have helped shaped the advancement of grasses, as shown by the instance in Figure below. Grasses supply most of the food spend by people worldwide. What various other grass seeds do you eat?
