Suggested Answers:

It protects the

internal parts of the stem.

It prevents the loss of water from the stem surface..

The cambial tissues

consist of meristematic cells which divide actively to increase the thickness of the stem.

The cork cambium produce new cork cells to increase the thickness of the cork layer. The vascular cambium

produces secondary phloem at its exterior and secondary xylem at its interior.

(1) 1. The cells are small.

2. Their cytoplasm

is dense.

(2) Mitosis.

The autumn wood is the secondary xylem which is formed in autumn and winter. During these seasons rainfall is. scanty and temperature is Low. A low temperature leads to an inactive cambium and therefore less xylem vessels are produced. Scanty rainfall Leads to the smaller and thick-walled xylem vessels. Thus the autumn wood appears darker and denser in texture.

A possible explanation is that the plant grows at a place on the. northern hemisphere where it can receive more sunlight from the south. This leads to a higher average temperature at side C and therefore a higher activity of the cambium there. More secondary xylem are produced at side Cand therefore BC is thicker than AB,

Suggested Answers:

The crop which shows a rapid increase in the area of cultivation is vegetables which shows a rapid decline is rice, In recent years, paddi. fields in Hong Kong have suffered a dramatic decrease. It is partly due to the urban expansion in the past two decades which resulted in a competition of land for construction and cultivation. Once more fresh water has to be directed to urban uses, urban expansion is also a cause of the scanty water supply in the rural areas which attacks agriculture there. Industrialization in the urban areas has attracted a lot of labour from the rural to urban areas, which results in a deficiency of rural labour force. Thus, many of the rice growers have abandoned their fields and moved to the

urban areas.

The above phenomenon is expecially true in the isolated parts of the N. T. For those fields bordering the rail and roads, many of them have been converted to intensive vegetables growing. The rapid increase in vegetables fields, on one hand, is to meet the Increasing demand in the Colony. It is because after the second World War, the consumption of vegetables in Hong Kong increased greatly due to the rapid increase in population. On the other hand, the relatively high profit is an encouraging factor. Profit from the growing and selling of vegetables can be nine, to ten times that from growing rice. The rapid increase is due to the improvements in

transportation in the N.T.

With the aid of the above informatión. Compare and contrast the agricultural sceneries in the North China Plain and Szechwan Basín.

Suggested Answers:

The North China Plain and Szechwan Basin are two important agricultural regions in China, The North China Plain, which is the largest plain in China, with over 60% of its land under cultivation, has the largest peasant population. The remote. inland basin of Szechwan, on the other hand, being a hilly region, with about 50% of its land under cultivation, has long been known as

Tien-fu-chih-kuo' or 'The Country with rich natural resources where agriculture has benefited a lot from its favourable natural endowment. A comparison of the two regions can be viewed from the following aspects:

A) Method of Framing

The Szechwan Basin is hilly in nature. Flat land is limited to only about 5% of the whole basin and occur. on only in patches. This mountainous nature has direct effect on farming method, Tarracing on slopes is outstanding. Fields are small and intensively cultivated.

Although intensive subsistence agriculture still exists in the North China Plain the

transformation in the last. twenty years cannot be overlooked. Due to the

flatness of the region, the . Land Reform Movement ang the rapid industrialization- since recent years, the subsistence agriculture in the region has been gradually transforming into modernized agriculture. In recent years, Communes are organised small land. holdings or poor peasant are combined and cultivation is brought under joint effort. With this Land Reform Movement, farm sizes are increased, and there is certain degree of mechanization.

B) Types of Crops

Szechwan, being situated to the South of Tsinling, has abundant rainfall and long growing season which enable the growth of double-cropped paddi. Rice is the most. important food crop and its annual yield represents more than 80% of the total food production. Besides the production of food crop, Szechwan has long been famous of its wide range-of cash crops produced, e.g.. cotton, tung oil, silk, sugar-eane, tea, tobacco and fruits.

The cooler temperatures of the North China Plain, on the other hand, favours the growth of wheat, barley, millet and kaoliang. These are. important food crops in the region. Cash crops are important, too. Cotton, peanut, soya-bean and fruit are produced in larg quantities.

C) Advantages benefited &

Difficulties to be

overcome

Because of the warm temperatures, long growing season and fertile soils, the productivity in the basin is very high. However, further agricultural development. depends on the importation of irrigation systems and transportation, and must. go hand in hand with industrial development, too.

Ins

spite of the fertile alluvial soils and the flatness of the region, the

the agriculture in the North China Plain suffers a lot from the frequent flooding of rivers and drought caused by the urreliability of rainfall. The operation of the Hwang-ho Multi-purpose Water Scheme has provided some checks against the natural hazards. Just the same, the scheme should go hand in hand with industrialization, urbanization and

improvements on transportation, thus, North

China can become China's
