Seed dispersal is aided by the wind, water and animals. Sees also dispersed when fruits burst with sudden jerks.
By wind: Seeds and fruits of plants are carried away by the wind, water and animals. Winged seeds such as those of drumstick and maple, light seeds of grasses or hairy seeds of aak (Madar) and hairy fruit of the sunflower, get blown off with the wind to faraway places.
By water: Seeds of aquatic plants or plants near water bodies usually develop floating ability in the form of a spongy or fibrous outer coat as in coconut and get dispersed by water.
By animals: Spiny seeds with hooks which get attached to the bodies of animals and are carried to distant places.
Dispersion of seeds by bursting of fruits: Some seeds are dispersed when the fruits burst with sudden jerks. The seeds are scattered far from the parent plant. This happens in the case of castor and balsam.

Solution:
Different methods of asexual production are:
Vegetative propagation: It is a type of asexual reproduction in which new plants are produced from
roots, stems, leaves and buds. Since reproduction is through the vegetative parts of the plant.
Budding: In this process, a new individual from a bulb-like projection, bud, grows and gets detached from the parent to form a new individual and it is mostly observed in yeast.
Spore formation: Spores are asexual reproductive bodies. A spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature & ow humidity. So they can survive for a long time. Under favourable conditions, a spore germinates and develops into a new
individual. Fungi on bread and plants such as moss and ferns reproduce through spores.
Fragmentation: In this process, a new organism is developed from the fragments of the parent body. Example, An alga breaks up into two or more fragments. These fragments or pieces grow into new individuals

Soapy was a homeless and jobless man. He needed a place to stay comfortably for three months during the approaching winter. He could get food and shelter at the houses of his known persons but he did not like to answer their odd questions and lose his freedom. He was a man of ego and considered himself a gentleman. He preferred to go to prison where he would follow the rules but live his own life. He made many attempts to get arrested. His luck failed at the restaurants. He was thrown outside but was not handed over to the police. He broke the glass of a window and stole an umbrella. He was arrested only after he had determined to lead an honourable life.

उत्तर:
कवि स्वतंत्रता का दीपक प्रत्येक परिस्थिति में जलाए रखने की प्रेरणा देता है। चाहे घनघोर अँधेरी रात हो, चाहे घनघोर वर्षा हो रही हो और बिजलियाँ कड़क रही हों। शत्रु पक्ष चाहे कितना ही प्रबल क्यों न हो, हमें हर स्थिति में उनसे मुकाबला करना है और इस स्वतंत्रता के दीपक को जलाए रखना है।
