1) Деление клетки. Это вид бесполого размножения у одноклеточных существ, при котором в материнской клетке все делится пополам, число хромосом удваивается и при делении материнской клетки пополам образуется две новой клетки.

2) Почкование. Вид бесполого размножения, при котором новый организм зреет на теле матери. У материнской особи обрадуется вырост, где формируется живой организм, и когда тот достигает зрелости, он отпочковывается и становится отдельной особью.

3) Размножение спорами. Вид бесполого размножения, при котором в специальных органах растения созревают споры. После того, как они достигают зрелости, они выходят в окружающую среду, прорастают при благоприятных условиях и образуют новый организм.

4) Половое размножение. В ходе этого размножения сливаются две половые (гаплоидные) клетки - яйцеклетка и сперматозоид (у растений спермий). В ходе этого образуется зигота, которая многократно делится и формирует зародыш.

5) Размножение черенками - вид вегетативного искусственного размножения растений, при котором часть вегетативного органа сажают в почву и тот образует новый растительный организм.

He asked the hall-porter whether there were any vacant rooms in the hotel. At that moment another traveller came to the hotel and asked the hal-porter for a room, too, The only vacant room was a double room, that, is, a room with two beds in it. “Do you mind if you spend the night in that room toget her?” the hall-porter asked. “It’ll be less expensive for you, you’ll each pay half”. At first the travellers didn’t like the idea, but just then it began raining hard, and they were too tired to go to another hotel, so they changed their minds. They spoke to each other and then told the porter that they agreed to spend the night in the same room. Their things were carried in, and soon the two men went to sleep to the accompaniment of the rain. Suddenly Mr Brown was woken up by a loud noise. It was quite dark. “What’s the matter?” Mr Brown asked in surprise. “Is anything the matter?" In a weak voice the second traveller answered, "I'm sorry, but I had to wake |ou up. I’ve got asthma. I feel very bad In addition I’ve got a terrible headache. If you don’t want me to die, open the window quickly”. Mr Brown jumped out of bed and began looking for his matches, but he couldn't find them in the dark, and the sick man went on moaning, “Air, air ... I want fresh air. I’m dying.”Mr Brown still couldn’t find the matches, so he tried to find the window. It took him some time, and at last he thought he had found it. But he was unable to open it. As the voice of the traveller grew weaker and weaker, Mr Brown in horror took a chair and broke the window with it. The sick man immediately stopped moaning and said that he was very grateful and felt much better. Then the two of them slept peacefully until morning.
