flower : : the specialized part of an angiospermous plant that occurs singly or in clusters, possesses whorls of often colorful petals or sepals, and bears the reproductive structures (such as stamens or pistils) involved in the development of seeds and fruit : blossom — Webster
Flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. — Wikipedia

- Big differences found in male and female jojoba...on October 15, 2021 at 1:51 pm
The hot and dry desert environment has led to big genetic differences between male and female jojoba plants, a discovery which could boost jojoba production and shed light on how plants adapt to environmental stress.

Clarence the giant schnauzer came into Penny Wagner's life as a puppy nearly eight years ago, at a traumatic time for her family.
- Adapting crops for future climate conditionson October 14, 2021 at 12:50 pm
With crops, farmers will adapt—they always have and always will. To help this adaptation, however, a Texas A&M AgriLife research project has used artificial intelligence modeling to determine what traits cultivars will need to be successful under changing climate conditions.
- Which plants and animals are affected by climate...on October 14, 2021 at 11:45 am
We've all seen the picture of the polar bear perched precariously on a melting iceberg. It's the obligatory poster child for any discussion about species that are endangered by climate change. It isn't alone, of course. To commandeer a clickbait cliché, you'll be amazed to hear about some of the plants and animals—from household names to virtual unknowns—that could be consigned to the history books by global heating. Here are just a handful of the many species that Fauna & Flora […]
- First global estimate of the importance of...on October 13, 2021 at 6:00 pm
About 175,000 plant species—half of all flowering plants—mostly or completely rely on animal pollinators to make seeds and so to reproduce. Declines in pollinators could therefore cause major disruptions in natural ecosystems, including loss of biodiversity.
- Widespread monoculture found to increase...on October 13, 2021 at 2:33 pm
A team of researchers affiliated with a host of entities across the U.S., has found evidence that suggests the practice of widespread monoculture has increased the prevalence of pollinator parasites. In their paper published in Proceedings of the Royal Society B, the group describes their study of bees in California's Central Valley, and what they found.

When an asteroid struck 66 million years ago and wiped out dinosaurs not related to birds and three-quarters of life on Earth, early ancestors of primates and marsupials were among the only tree-dwelling (arboreal) mammals that survived, according to a new study.
- Researchers conduct first tissue culture study...on October 11, 2021 at 11:20 am
Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences surveyed all known sites of Passiflora xishuangbannaensis (known as Xishuangbanna passion flower) over past years. They found only 38 individuals in its native habitat, confirming it as a plant species with extremely small population. Nine Passiflora species are endemic to Yunnan with most species occurring in South America, making P. xishuangbannaensis highly significant and emblematic to the […]
- Birds learn to avoid plants that host dangerous...on October 7, 2021 at 3:00 pm
Young birds that eat insects with conspicuous warning colouration to advertise their toxicity to would-be predators quickly learn to avoid other prey that carry the same markings. Developing on this understanding, a University of Bristol team have shown for the very first time that birds don't just learn the colors of dangerous prey, they can also learn the appearance of the plants such insects live on.
- Loved to death: Australian sandalwood is facing...on October 7, 2021 at 1:10 pm
The sweet, earthy fragrance of sandalwood oil has made it immensely popular in incense sticks, candles and perfumes. But its beautiful scent may also be its downfall—Australian sandalwood (Santalum spicatum) is facing extinction in the wild.
