In this video we will cover:-
All flowering plants show sexual reproduction.A look at the diversity of structures of the inflorescences, flowers and floral parts, shows an amazing range of adaptations to ensure formation of the end products of sexual reproduction, the fruits and seeds. To a biologist, flowers are morphological and embryological marvels and the sites of sexual reproduction. Much before the actual flower is seen on a plant, the decision that the plant is going to flower has taken place. Several hormonal and structural changes are initiated which lead to the differentiation and further development of the floral primordium.
