वैशाख में चाहे एकाध बार कुलेल कर लेता हो; पर हमने तो उसे कभी खुश होते नह ीं देखा। उसके चेहरे पर
एक स्थायी ववषाद स्थायी रूप से छाया रहता है। सुख-दखु , हानन-लाभ, ककसी भी दशा में उसे बदलते नह ीं
देखा।ऋवषयों-मुननयों के जितन गुण हैं, वे सभी उसमें पराकाष्ठा को पहुुँच गए है; पर आदमी उसे बेवकूफ
कहता है। सद्गुणों का इतना अनादर कह ीं नह ीं देखा। कदाचचत सीधापन सींसार के ललए उपयुक्त नह ीं है।

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.
