What does the fox say!! |
Day 331 - Interaction between insects and
flowering plants shaped the development of both groups, a process called
coevolution. In time flowers evolved arresting colors, alluring fragrances, and
special petals that provide landing pads for their insect pollinators.
Uppermost in the benefits package for insects is nectar, a nutritious fluid
flowers provide as a type of trading commodity in exchange for pollen
dispersal. The ancestors of bees, butterflies, and wasps grew dependent on
nectar, and in so doing became agents of pollen transport, inadvertently
carrying off grains hitched to tiny hairs on their bodies. These insects could
pick up and deliver pollen with each visit to new flowers, raising the chances
of fertilization.
Day 323 – Bees can
sense a flower's electrical charge, which tells them if the flower's worth visiting.
Everyone
knows that bees buzz around flowers in their quest for nectar, but scientists
have now learned that flowers are buzzing right back — with electricity. Plants
generally have a negative electrical charge and emit a weak electrical signal and
scientists have known for years that bees' flapping wings create a positive
electrical charge of up to 200 volts as they flit from flower to flower. The bees
— busy as they famously are — don't have time to waste visiting pretty flowers
whose nectar has just been taken by another insect, so the flower and bee have
an electric communication that provides them both with what they need. The bees
get nectar and the flowers get pollinated without wasted effort.
Day 325 – Science has proven it! Flowers
make people happy! We of course knew, but read on… The first study involved 147
women. All those who got flowers smiled. Make a note: all of them. That's the
kind of statistical significance scientists love. Among the women who got
candles, 23% didn't smile. And 10% of those who got fruit didn't smile. We still like candles and fruit, but flowers make people the happiest!
Day 316 - Much of the reason orchids are so
widespread is thanks in part to humans' affinity for and desire to grow them. It
is thought that the symmetry of the flower could have a lot to do with why
people are so fond of orchids. An orchid has bilateral symmetry — like a human
face — so if a line is drawn vertically down the middle of the flower, the two
halves are mirror images of each other.
Day 320 - Researchers at the John Innes
Center and the University of East Anglia, both located in Norwich in the United
Kingdom, studied how petals and leaves grow in a type of small flowering plant
called Arabidopsis.
They discovered that concealed maps within the flower buds are made up of
patterns of arrows that act as instructions for how each cell in the bud should
grow. As such, the maps essentially influence a flower bud's cell polarity, or
the functions of the cells. The study's findings not only shed light on why
geranium petals are unlike rose petals, they also explain why an individual
flower's petals and leaves are different shapes.
