Detailed explanation-1: -Totipotency is the capacity to generate a whole plant from any vegetative single cell. This characteristic of a plant cell is used to produce thousands of plantlets through tissue culture.

Detailed explanation-2: -1 Totipotency. Totipotency is defined in Wikipedia as the ability of a single cell to divide and produce all the differentiated cells in an organism, including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes.

Detailed explanation-3: -A cell (and only a single cell) can be considered as totipotent if it is able to autonomously develop into a whole plant via embryogenesis.

Detailed explanation-4: -Plant regeneration refers to the physiological renewal, repair, or replacement of tissue in plants (Ikeuchi et al., 2016). The totipotency or pluripotency of plant cells underlies the ability of plants to regenerate, reflecting the high plasticity of cell fate.
