The chapter Reproduction in Flowering Plants is very important. Each year many questions are there from this section. 

• All living things reproduce their own kind. This is called reproduction.
• Plants reproduce through flowers.
• Fruits are formed through flowers.
• Ferns, mushrooms and moulds reproduce through tiny seed-like structures called ‘spores‘.
• The multiplication or propagation of plant in which new plants grow from any part of the parent is called vegetative propagation. 
• Onion, ginger, and potatoes are underground stems.
• Rose, bougainvillea, and sugarcane can be grown by stem cutting.
• Sweet potato is a modified root.
• Bryophyllum reproduces from leaves.
• Plants having weak stems like strawberry reproduce by a structure called runners.
• Layering is the method of reproduction in Jasmine. 
• The growth of the baby plant from a seed is called germination.
• The baby plant coming out of a seed is called a seedling.
• The process of spreading seeds to different places is called dispersal of seeds.
• Seeds which are dispersed by wind have wings or tuft of hair on them.
• Seeds dispersed by water such as coconut have a fibrous outer coat, hence it is easily carried away by water.
• Madar (मदार) and cotton seeds are dispersed by wind.
• Seeds dispersed by animals have hooks or spines that attach to the animal’s body and get carried to different places.
• Some fruits on drying explode. The force of explosion disperses the seeds.
• Pea seeds and honestly seeds get dispersed by the explosion.
• Vegetables grow best in soil containing enough minerals.
• Cabbage, peas, cauliflower, carrot, and radish need cool climate.
• Brinjal, pumpkin, and ladies finger grow well in a warm climate.
• Melons, watermelons, potatoes, and onion grow best in sandy soil.
• Paddy grows in wet and clayey soil.
• Wheat grows well in a temperate soil.
• Cotton grows best in black soil.
• Jute grows best in alluvial soil in a hot and wet climate.
• Tea and coffee grow well on hill slopes because they need plenty of heat and water that does not remain standing for a long time near roots.
• To get a high yield of crops:
  • Prepare the soil properly.
  • Use healthy and ripe seeds for sowing.
  • Add manures or fertilizers to the soil.
  • Irrigate the soil well.
• Insecticides and pesticides are sprayed on crops to protect them from pest.
• Fungicides can be used to kill microbes which are responsible for the sum of fungal diseases.
• Storage should be done in waterproof, insect proof, airtight and sealed plastic containers.
