260393 Arrange the steps of somatic hybridization in correct chronological order:

I. Protoplast fusion using electric shock (electrofusion) or chemical treatment.
II. The removal of the cell wall of one cell of each type of plant using cellulase enzyme to produce a somatic cell called a protoplast
III. The formation of the cell wall induced using hormones
IV. The cells are then grown into calluses which then are further grown to plantlets and finally to a full plant, known as a somatic hybrid.

260394 During organogenesis in plant tissue culture:

1 an excess of auxin will often result in a proliferation of roots, while an excess of cytokinin yield shoots
2 an excess of auxin will often result in a proliferation of roots, while an excess of gibberellins yield shoots
3 an excess of cytokinin will often result in a proliferation of roots, while an excess of gibberellins yield shoots
4 an excess of gibberellins will often result in a proliferation of roots, while an excess of ethylene yield shoots

260395 Plant tissue culture may offer certain advantages over traditional methods of propagation, including all the following except:

1 The production of plants that exhibit large variations from the parent plants.
2 Quickly production of mature plants.
3 The regeneration of whole plants from plant cells that have been genetically modified.
4 Storage of genetic plant material to safeguard native plant species.
