$\huge\pink{Answer}$

1. Asexual reproduction is a mode of reproduction in which only one parent is involved to reproduce offspring. In asexual reproduction,the offsprings produced are exact copies of their parents. It is generally observed in very small sized organisms. Binary fission, Budding, Fragmentation etc
2. Wind and Water Pollination

• No bright colors, special odors, or nectar.
• Small.
• Most have no petals.
• Stamens and stigmas exposed to air currents.
• Large amount of pollen.
• Pollen smooth, light, easily airborne.
• Stigma feathery to catch pollen from wind.
• May have staminate and pistillate flowers, may be monoecious or dioecious.

3. ADVANTAGES = a) Faster and more certain method of propagation.

b) New individuals produced have exactly identical qualities as their parents. This preserves the characteristics of food and flower crops.

DISADVANTAGES = a) Does not produce new varieties.

b) Leads to overcrowding around the parent plant.
