New 'CRISPR-Combo' method boosts genome editing power in plants

Ten years ago, a new technology called CRISPR-CAS9, made it possible for scientists to change the genetic code of living organisms. As revolutionary as it was, the tool had its limitations. Like the first cell phones that ...

Forest plants now flower a week earlier than a century ago

Early flowering plants in European forests today start their flowering season on average a week earlier than they did a hundred years ago. This is reflected by herbarium specimens, as Dr. Franziska Willems and Professor Oliver ...

Research unveils evolution and seed micromorphology in Impatiens

The species Impatiens linnaeus is notoriously difficult to classify morphologically, and the semi-succulent stems, fleshy leaves, and extremely fragile flowers make it challenging to prepare good herbarium specimens. Compared ...

Bumblebees' nutrition influences their pesticide resistance

How susceptible bumblebees are to a common fungicide depends on the flowering plants to which it is applied on and how diverse the food supply is that is available to the insects. Monocultures can increase the insects' sensitivity ...

Flower

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. The grouping of flowers on a plant are called the inflorescence.

In addition to serving as the reproductive organs of flowering plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.
