Plants have two different types of 'transport' tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant.

Plants use two different strategies; transpirational pull and root pressure for the transportation of water and minerals during day and night.

Root Pressure is the positive pressure created by the movement of water from the roots to the soil for upward movement of water. The effect of root pressure in the transport of water is more important at night.

Transpiration pull is the pull of water as a result of tension created by transpiration in the aerial parts of the plant. It is the major driving force of water movement upwards in a plant during the day. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots.

if we don't conserve them then our life will also come to an end and earth will be destroyed..

There are many people who are participating in the conservation of forest and wildlife there are many associations, there are different companies such as WWF - World Wildlife Fund etc.

Given:  A square ABCD an equilateral triangle ABC and ACF have been described on side BC and diagonal AC respectively.

To Prove :-  {tex}ar( ∆BCE ) = \bf{ \frac{1}{2} ar( \triangle ACF ) . }{/tex}

Proof :-  Since each of the ∆ABC and ∆ACF is an equilateral triangle, so each angle of his strength is one of them is 60°. So, the angles are equiangular, and hence similar.

 => ∆BCE ~ ∆ACF.

We know that the ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.

{tex}\bf{ \frac{ ar( \triangle BCE ) }{ ar( \triangle ACF ) } = \frac{{BC}^{2} }{ {AC}^{2}} = \frac{{BC}^{2}}{2{(BC)}^{2}}. }{/tex}

[ Because, AC is hypotenuse => AC = √2BC. ]

{tex}\bf{ \implies \frac{ ar( \triangle BCE ) }{ ar( \triangle ACF ) } = \frac{1}{2} . }{/tex}

Hence,  {tex}\boxed{ \sf ar( \triangle BCE ) = \frac{1}{2} \times ar( \triangle ACF ) . }{/tex}

Power sharing in simple words is sharing of responsibility & powers among diffent organ of govenment. Power sharing is a strategy for resolving disputes over whoshould have the powerful position in the social hierarchy.

It is very difficult to make changes to the power sharing arrangements between the union government and state governments due to the following reasons :

(i) There is clear distinction of power between state and centre through three list system.
(ii) In this arrangement constitution clearly lays down the division of powers between Union and State. So for any changes, it has to go through the amendment procedures which is difficult.
(iii) Here, the centre has a general authority, but the regional or state governments are given autonomy. Therefore, interference in each other’s jurisdiction for any change is difficult.

(i) The sharing of powers among political parties, pressure groups and movements ensures the influence in decision making process as democracy implies people’s choice among various contenders.
(ii) Regarding political parties this sharing takes place in the way of political competition among different parties. This in turn ensures that power does not remain in one hand.
(iii) In the case of coalition government this sharing becomes direct when two or more parties form an alliance to contest election and if their alliance is elected.
(iv) At the same time, pressure group and movements influence power sharing through dharna, rallies, protest, strike etc.
(v) In anotherway by becomingthe member of committee ora part of the planning commission.

(i) Labour was in abundance.
(ii) Job opportunities were few.
(iii) Job seekers who came from villages had to spend the night under bridges or in night shelters and they had no place to stay in the city.
(iv) Much of the work was seasonal in nature such as bookbinding.
(v) Wages were low and life was difficult when prices of goods in the city rose sharply.
(vi) Workers had to look for odd jobs when they could not find proper employment in factories.

In the 19th century self sufficiency in food meant lower living standards and social conflict in Britain .

•   Population growth from the late 18th century has increased the demand for food grains in Britain . As urban centres expanded and industry grew the demand for agricultural products went up pushing the food grain prices up
•  Under pressure from landed groups the government also restricted the import of crops. The laws allowing the government to do this was termed as the corn law. Unhappy with the high food prices urban dwellers and industrialists forced the abolition of corn laws.
•  After the corn laws were scapped food could be imported more cheaply than it could be produced within the country. British agriculture were unable to compete with the imports. vast areas were left unccultivated . Thousands of men and women were thrown out of work.

Democracy is a rule 'of the people' by the people' and 'for the people'. The representatives of the people carry on the work of administration. Some conditions are required for the implementation of the ideals, principles and norms of democracy. They are:

India was facing many issues in the agricultural sector. A few of them are highlighted below:

1. The Britishers had introduced the Zamindari system. This implied that every owner or zamindar had complete control over land. The farmers worked on it, and the ultimate benefits were taken by the zamindars. The actual tillers of the soil were left without much crop, money and were helpless in this situation.

2. The average size of holdings was very small. It was more prominent in densely populated areas such as Bihar, Uttar Pradesh, Punjab etc. Subdivision and fragmentation of holdings led to low agricultural productivity.

3. Good quality seeds were not distributed. The farmers had to pay an exorbitant amount to get access to these better seeds.

4. Deletion and lack of replenishment of the soil was another issue. Manure and fertilizers were not provided to the farmers, which could have helped them.

5. In India, rainfall is uncertain and irregular. This implies that adequate water is not available for the crops.

6. Maximum work was done by the manual labour. Although, other countries were using advanced machinery in the agriculture sector.

7. Large areas of land were suffered from soil erosion through water and wind.

8. The lack of marketing facility implied that the workers had to be depended upon the middlemen to transfer their goods to the market areas.

9. There were no storage facilities in rural areas. The farmers had to sell their produce immediately after harvesting it at the current price was very low.

10. Many villages were not connected with proper roads. The lack of cheap and efficient means created further problems to take their crops to the market.

11. The farmers did not have adequate capital to support their requirements. They had to resort to money lenders who charged a high rate of interest and exploited them.

All such issues prevailing in the economy led to the introduction of various technological and institutional reforms made in India in the agricultural field are:

1. Land reforms: Consolidation of holdings, the abolition of zamindari system etc

2. Agricultural reforms: Green revolution and White revolution

3. The issue of Kisan credit cards, Personal accident insurance scheme

4. Weather bulletin for farmers.

5. Provision of crop insurance for farmers in case of drought, flood, etc

6. Provision of HYV seeds, manures, fertilisers, insecticide and pesticide.

7. Providing storage facility and transport facility.
