Question

26. A good reason to regenerate plants via protoplast cultures, is

• Rapid propagation of plant material
• Minimise genetic variation
• Somaclonal variation

27. Plant protoplasts are prepared from all of these explants except:

• apical meristems
• pollen
• leaf mesophyll
• roots

28. Micropropagation of plants helps to:

• All the above
• Counter disease
• Develope agronomic traits

Answer 1

26. somaclonal varations

protoplast culture is used in development of hybrid plants through the fusion of somatic protoplasts of two different plant species or varieties is called somatic hybridization

27. roots

roots generally have cells with more resistant walls so they cannot be culture in protoplast culturing.

28. counter disease

the main advantage of micropropagation is the production of many plants that are clones of each other and also used to produce dissease free plants
