If a leaf segment of Bryophyllum is planted in the soil, it produces new plants. This is because its leaf has
Higher concentrations of auxins
Higher concentrations of cytokinins
Small embryos
Buds
Bryophyllum, also known as the mother-of-thousands or mother-of-millions plant, is a succulent plant that belongs to the Crassulaceae family. One of its unique characteristics is the presence of buds on the margins of its leaves.
If a leaf segment of Bryophyllum is planted in the soil or simply placed on a moist surface, these buds have the ability to develop into new plants. This vegetative propagation method is known as leaf propagation or leaf cloning.
Each bud on the leaf margin is capable of forming adventitious roots and shoots. As the leaf segment is provided with the necessary moisture and nutrients, the buds start to grow and develop into complete plantlets with their own root systems. Eventually, these plantlets become independent individuals, separate from the parent leaf.
Bryophyllum's ability to produce new plants from leaf segments is an example of asexual reproduction, as it does not involve the formation of seeds or the fusion of gametes.
Hence, the correct answer is option 4.
