Ответ:

Это — верхушечные и вставочные меристемы. Те постоянные ткани, клетки которых дифференцируются из производных клеток первичной меристемы, называют первичными. ... Вторичными называют меристемы, которые формируются в вегетативных органах позднее первичных и обеспечивают их вторичный рост.

Edinburgh is the capital of Scotland and one of the most beautiful cities in Europe. It lies in seven hills and goes down those hills to the sea. The highest hill is three hundred metres above the sea. From the street in the centre of the city you can see ships coming to Edinburgh from different countries of the world.

In the « old town » the streets are narrow. The tall houses with narrow windows go up the hills to Edinburgh castle, which is one thousand years old. The modern town lies at the foot of the hills. The streets are straight and well planned, so it is easy to walk in the city when you go sightseeing in Edinburgh. Many great men have lived and worked in Edinburgh. Robert Burns, the great Scottish poet, published his first book of poems in Edinburgh. There is a monument to him in the city. Edinburgh is also proud of Walter Scott, the father of the historical novel in world literature, and Robert Louis Stevenson, a famous English writer.

This city is a great educational centre, there are three universities. Such scientists as John Napier who invented logarithms, Adam Smith, the father of political economy, Alexander Bell, the inventor of the telephone also lived and worked in Edinburgh.

The Holyrood Palace in Edinburgh is another official residence of the Queen besides Buckingham Palace. This Palace is a museum with a number of museums inside it. There are the Museum of Childhood with its unique collection of toys and games, the Writer’s Museum, the People’s Story Museum, which tells the story of ordinary people.

It seems that past and present live in Edinburgh side by side, and it gives a special charm to the city. But in fact, Edinburgh is a busy town. People are employed in manufacturing industry: electrical and electronics engineering, paper printing and publishing, food and drink industry.
