THTHEE BEBEESES

Page 2: The bees

Bees are flying insects closely related to wasps and ants, and are known for their role in pollination and for producing honey and beeswax.

Page 3: The bees

Pollination is the transfer of pollen grains from the anther of the stamen to the stigma of the pistil.

Page 4: The bees

There are nearly 20,000 known species of bees .

Now we will see the honey bees.

Page 5: The bees

The European (or Western) honey bee, (Apis mellifera), is the best known bee species and one of the best known of all insects.

Page 6: The bees

They live in the beehive. It is made of beeswax, and it has

some honeycombs formed with hexagons, they make these

hexagons to save space in the beehive and work, because in

this way they use less beeswax and less energy.

Page 7: The bees

In the beehivebeehive there are three types of bees:

Drone

Queen

Worker

Page 8: The bees

She is the only fertile female who puts fertilized eggs that give origin to working unfertile bees and puts not fertilized eggs that give origin to fertile drones, for a mechanism named parthenogenesis.

Page 9: The bees

The workers are females smaller than the queen, the only difference between them is that the workers aren´t fertile. They live approximately 85 days.

They are all his life working in the beehive(when they are young) or gathering(when they are adults).

Page 10: The bees

The drones are the male bees in a beehive. His only mission is to fertilize the queen. They live approximately 3 months. When there is not enough food, the drones are expelled by the workers from the beehive

Page 11: The bees

First, the bee gathers the pollen. Later it fills his maw with this substance and with one enzyme transforms it into glucose. This bee gives the mixture to the workers. And they dehydrates and adds enzymes that transform it into honey. After this process the honey loses a lot of water (80 %).

The honey is deposited in the cells The bee-keeper extracts the honey of the honeycomb.

Albert Einstein said: without bees the human beings only can survive 4 years. But.... Why? The bees are very important in the fertilization of plants, this way the fruits, food are formed. Food that animals need to live...

Page 13: The bees

Many bees are dying: Due to a parasite that affects them when they are in the egg and damages his intestine. They are born this way:

Due to pesticides, chemical products that the human beings use.

Due to the pollution (climate change).

Page 14: The bees

We have to do everything possible to save the bees.If we do not want to verify that what Albert Einstein said is true or a false...

And remember if you found a bee, do not shout, do not scare and the bee won´t sting you.
