The sources used by historians in the period 700 to 1750 (the Medieval Period) were quite different from the ones used in the period of Gupta dynasty and Hashavardhana.

Administrative measures of Alauddin Khilji:
- Sultan Alauddin Khalji established a strong central government during his reign in which the Sultan was the head of the administration.
- The Sultan considered himself as a representative of God or “Shadow of God”. As a result, he restricted matrimonial relations among nobles and officers as well as he prohibited secret meetings and parties etc.
- He also minimized the powers of Ulema in the affairs of State and religion.
- Alauddin Khalji paid his soldiers in cash. In order to enable his soldiers to buy products at cheap rates, he fixed the prices of commodities in and around Delhi. The markets were closely supervised and shopkeepers and traders charging above the fixed price were severely punished.
- Alauddin had maintained a huge army. To meet the expenses of such a huge army, he introduced many revenue reforms. The land was carefully measured and the taxes to be paid to the state were fixed. Taxes were collected by the revenue officers who were appointed for this purpose. The revenue to be paid was increased from one third to half and had to be paid in cash.

- Buddhism was founded by Gautama Buddha.
- Buddha was born as Prince Siddhartha at Lumbini near Kapilavastu (in present Nepal) in 566 BC.
- He was the son of Suddhodhana and Mahamaya. Suddhodhana was the chief of the Sakya clan. Due to this, Buddha was also known as ‘Sakyamuni’.
- His mother died either giving birth to him or after seven days. Siddhartha was brought up by his maternal aunt, Prajapati Gautami. This gave him the name ‘Gautama’.
- He was married to Yashodhara and had a son, Rahula.
- He left his home at the age of 29 to become an ascetic. This event is called Mahabhishkramana.
- The idea of renunciation occurred to the Buddha after he saw four different states of man – sick man, old man, corpse and ascetic.
- Buddha wandered for seven years and at the age of 35 attained enlightenment at Uruvela while meditating under a banyan tree on the banks of the river Niranjana. This tree came to be known as ‘Bodhi tree’ and the place became Bodh Gaya (in Bihar).
- He gave his first sermon at Sarnath near Varanasi. This event is called Dharmachakra Pravartana/ Dhammachakkappavattana.
- He died in 483 BC under a Sal tree in Kushinagar (in UP). This event is called the Mahaparinirvana.
- The term ‘Buddha’ means ‘enlightened one’.
- Important contemporaries of Buddha were Mahavira Jaina, Kings Prasenjit, Bimbisara and Ajatasatru.

Carbon and energy requirements of the autotrophic organism are fulfilled by photosynthesis. The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy in the presence of chlorophyll is called photosynthesis.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
The raw materials for photosynthesis are carbon dioxide and water. The green plants take carbon dioxide from air for photosynthesis. The carbon dioxide gas enters the leaves of the plants through the stomata present on their surface. The water required by the plants for photosynthesis is absorbed by the roots of the plants from the soil through the process of osmosis. The water absorbed by the roots is transported upwards through the xylem vessels to the leaves where it reaches the photosynthetic cells and utilized in photosynthesis.
The conditions for photosynthesis are sunlight, chlorophyll, carbon dioxide and water.
Factors affecting the rate of photosynthesis are (i) Light (ii) Carbon dioxide (iii) Water (iv) Temperature (v) Mineral elements.
The process of photosynthesis takes place in the green leaves of a plant. The carbon dioxide gas required for making food is taken by the plant leaves from the air which enters the leaves through tiny pores called stomata. Water required for making food is taken from the soil which is transported to the leaves from the soil through the roots and the stem. The sunlight provides energy required to carry out the chemical reactions involved in the preparation of food. The green pigment called chlorophyll absorbs sunlight energy.
The photosynthesis takes place in three steps:
(i) Absorption of sunlight energy by chlorophyll.
(ii) Conversion of light energy into chemical energy and splitting of water into hydrogen and oxygen by light energy.
(iii) Reduction of carbon dioxide by hydrogen to form carbohydrates like glucose by utilising the chemical energy.

A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve similar purposes to maps, but unlike maps, do not distort the surface that they portray except to scale it down. A globe of Earth is called a terrestrial globe.

Reported or indirect speech is usually used to talk about the past, so we normally change the tense of the words spoken. We use reporting verbs like 'say', 'tell', 'ask', and we may use the word 'that' to introduce the reported words. Inverted commas are not used.
