It can be asexual or sexual. In asexual, new plants are obtained without seeds and in sexual they are obtained from seeds.
Vegetative
propagation is a part of asexual reproduction where new
plant is grown from vegetative parts of plant.
Plants obtained from vegetative propagation grow faster, bear fruits, flowers fast and are exact copies of the parent.
e.g.: Rose – stems, potato, ginger, turmeric – buds, bryophyllum – leaves, sweet potato, dahlia –roots.
Yeast reproduces by budding, algae by fragmentation, fungi, moss, ferns by spore formation.
External
fertilization i.e. fusion of male and female gametes
outside the body is common in aquatic animals.
Viviparous animals give birth to young ones, oviparous animals lay eggs.
