Question 7.
What is meant by the term fertilisation? List the stepwise manner leading to formation of an embryo.
Answer:
The process in which the male gamete fuses with female gamete to form a new cell (called zygote) is called fertilisation.
*When the pollens are deposited on the stigma of the pistil, it begins to germinate. *After sometime, a long pollen tube is developed from the pollen grain which passes through the style towards the female gametes in the ovary.
*The male gametes move down the pollen tube and the tube enters the ovule present inside the ovary.
*The tip of pollen tube bursts and the male gamete comes out of the pollen tube. *Inside the ovary, the male gametes fuse with the female gametes present in the ovule to form a fertilised egg cell which is called zygote.
*The zygote develops into an embryo which is a part of a seed that develops into a new plant.

The nation has faced religious violence, casteism, naxalism, terrorism and regional separatist insurgencies. India has unresolved territorial disputes with China which in 1962 escalated into the Sino-Indian War, and with Pakistan which resulted in wars in 1947, 1965, 1971 and 1999. India was neutral in the Cold War, and a leader in the Non-Aligned Movement. It had a brief era of alliance with former Soviet Union, when Pakistan was closely allied to the United States and People's Republic of China.
India is a nuclear-weapon state, having conducted its first nuclear test in 1974, followed by another five tests in 1998. From the 1950s to the 1980s, India followed socialist-inspired policies. The economy was influenced by extensive regulation, protectionism and public ownership, leading to pervasive corruption and slow economic growth. Beginning in 1991, neoliberal economic reforms have transformed India into the third largest and one of the fastest-growing economies in the world. From being a relatively destitute country in its formative years, Indian Republic has emerged as a fast growing G20 major economy with high military spending,and is seeking a permanent seat in the United Nations Security Council.
India has sometimes been referred to as a great power and a potential superpower given its large and growing economy, military and population.
