Ответ:

Генеративными частями цветка являются тычинки, предопределяющие мужской пол, и пестики, предопределяющие женский пол. Для повышения эффективности опыления цветки у многих растений собраны в простые и сложные соцветия. После двойного оплодотворения семязачаток превращается в семя, а на месте завязи формируется простой или сборный плод.

3. POLL: AEU CITIZENS BACK EXPANSION

European Union citizens back the eastward expansion of their trade bloc, but have little idea what the EU bureaucracy is doing about it, according to poll results released Thursday Nov., 23. Conducted in all 15 EU nations between July and October, the poll found majorities support membership for Bulgaria, Hungary, Poland, the Czech Republic, Slovakia, Estonia and Latvia. But it found only one in five citizens who has even heard that EU governments plan to open talks next spring on a new treaty that will pave the way for expansion. Those negotiations will aim to play the financial groundwork for expansion and streamline cumbersome EU decision, making rules that were made for a union of fewer than a dozen members. Britain has fiercely guarded its sovereignty from encroachment by EU institutions and has won the right to opt out of EU labour laws and plans for a common EU currency. The poll found 27 per cent believe efforts to bring the union closer together were «very important», while 44 per cent said they were «fairly important». Sixteen percent said those efforts were not important, while the rest had no opinion.

4. ANIMAL DRIVERS STALK THE ROADS OF BRITAIN

Motorists are animals on the road and follow the law of the asphalt jungle when they get behind the wheel, a report out today says. The research shows that animal-like aggression is a major cause of accidents. Each day 13 people die and 800 are injured on Britain's roads and for every accident involving injuries there are up to ten more, in which there is only damage to vehicles. The report from the AA's University of Newcastle upon Tyne says, it is the animal-like desire to protect territory and to dominate the pack that makes motorists drive aggressively. When trying to overtake, for instance, many drivers do not wait until it is safe but «challenge» other cars for dominance or block other vehicles as a way of protecting their territory. The report says: «It is necessary for only a few drivers to behave aggressively to protect what they regard as their territory for many others to feel threatened».

Most drivers admit they speed regularly but few say it is dangerous, the report says: «If serious inroads are to be made into current attitudes to speeding, the prevailing view that it is neither a crime nor dangerous must be changed. All drivers need to be convinced that speed is a weapon that can kill».
