Endocytosis is swallowing up of food and other substances (bacteria, viruses) from external medium by the plasma membrane. This is possible only when plasma membrane is in direct contact with external medium. It occurs only in animal cells. In plant cells, a cell wall is present over the plasma membrane. Therefore, their plasma membrane cannot perform endocytosis.
(i) When the axis of the monsoon trough lies over the plains, rainfall is good in these parts. On the other hand whenever the axis shifts closer to the Himalayas, there are longer dry spells in the plains and widespread rain in the mountainous areas.

Withdrawal or the retreat of the monsoon is a more gradual process. The withdrawal of the monsoon begins in the north-western states of India by early September. By mid-October, it withdraws completely from the northern half of the peninsula. The withdrawal from the southern half of the peninsula isRead more
Withdrawal or the retreat of the monsoon is a more gradual process. The withdrawal of the monsoon begins in the north-western states of India by early September. By mid-October, it withdraws completely from the northern half of the peninsula. The withdrawal from the southern half of the peninsula is fairly rapid. By early December, the monsoon withdraws from the rest of the country. In the islands, the withdrawal takes place progressively from north to south from the first week of December to the first week of January.
The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region.

The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region. They usually influence the weather of the north and north-western regions of India. Tropical cyclones occur during the monsoon as well as in October-November, and are part of the easterly low. These disturbances affect the coastal regions of the country. They sometimes cause disasters on Orissa and Andhra Pradesh coasts.

The types of houses which are built in Rajasthan, in the Terai region, Goa and Mangalore, Assam and the reasons there of are as mentioned below:
(i) The houses in Rajasthan have thick walls and flat roofs. The main reason is that it is an area with randy plains covered with sand dunes which receives very little rainfall. People experience the highest diurnal range of temperature. So to protect themselves from heat and cold, they build houses with thick walls and fat roofs.
(ii) The houses in the Terai region, in Goa and Mangalore have sloping roofs, which is due to heavy snowfall and rainfall in these areas.
(iii) The houses in Assam are built on stilts because there is maximum rainfall in the northeastern part of the country due to the southwest. monsoon. Sometimes, it causes heavy flood. So, the houses in Assam are built on stilts to avoid damage during the floods.
