Pollen – tasty and healthy

Pollen – tasty and healthy

Pollen – tasty and healthy


When springtime comes around, bees get busy and pollen fills the air. For people who suffer from allergies, pollen seems to be a curse rather than a blessing. Some plants produce astronomical quantities of pollen. Just one birch catkin, for example, may release over five million grains of pollen, and a typical birch tree will likely have several thousand catkins. For people who suffer from hay fever, this proliferation of pollen results in great discomfort.
But our lives depend on this unique dust. Pollen consists of tiny grains that are produced in the male organs of flowering and cone-bearing plants. So, plants produce pollen in order to reproduce. The female organ of a flower (the pistil) needs pollen from the male organ (the stamen) in order to be fertilized and produce fruit. Pollen grains are tiny and we can hardly see them with the unaided eye. However, under a microscope we can see that both the size and the shape are unique to each particular species. The scientists often study the pollen grains to identify plants that people cultivated centuries ago.

Dragonfly – insect with ancient wings


Dragonflies are flying insects with two pairs of see-through wings, huge eyes, and long bodies. They live near lakes, streams, and ponds throughout most of the world. There are about 2,500 species of dragonfly. Dragonflies are ancient insects, dating back before the beginning of the reign of the dinosaurs some 225 million years ago. Present–day dragonflies do not differ very much from their ancestors.
Dragonflies feed mostly on other insects. They are very fast and their large eyes allow them to spot prey above, below, in front, behind, and on both sides of them. They can fly at the speed of up to 57 km / h. Dragonflies are considered the most dangerous predators.

Bacteria – tiny living things


Bacteria are small unicellular living things, that can be found everywhere. Most bacteria can be seen only with a microscope. Only viruses are smaller. There are many species of bacteria, some of them can live in extreme environments.
Bacteria take in food and send out waste through their cell walls. Most bacteria reproduce by dividing down the middle to form two separate cells. Billions of bacteria may form from a single bacterium in only 24 hours.
For breathing most bacteria need air and are called aerobic. But there are bacteria that live without air, anaerobic, and the oxygen in the air is poison for them. They feed on organic substances.

Glacier – ice mountain


Glaciers are flowing masses of ice, created by years of snowfall and cold local temperatures. Thousands of years ago, large parts of the world were covered with glaciers. Today glaciers exist all over the world. Greenland and Antarctica are covered by thick sheets of glacier ice. There are smaller glaciers in the Rocky Mountains of North America, in the European Alps, in the Andes of South America, and even at mountainous points along the equator.
Glacier ice today stores about three fourths of all the freshwater in the world.
Continental glaciers begin with a decrease in temperature and an accumulation of snow, over tens of thousands of years.
