All plant cells

Answer 2

Totipotency is the ability of a living somatic plant cell to develop into a complete plant. It was first demonstrated by Steward et. al (1964) using phloem cells of carrot. This technique is now used for multiplying rare and endangered plants through micro- propagations. This technique is widely used for multiplying plants e.g. - Chrysanthemum, Dioscorea floribunda, Coleus, Crotons, carnation plants etc.
