Micropropagation Quiz

What is the first stage of micropropagation?

• Acclimatization

• Rooting

• Establishment

• Multiplication

What is direct organogenesis?

• Formation of callus from an explant

• Formation of embryos from callus

• Formation of shoots or roots without callus formation

• Formation of roots from callus

What is the purpose of callus in micropropagation?

• To produce secondary metabolites

• To enhance virus transmission

• To inhibit cell division

• To prevent acclimatization

What does indirect embryogenesis involve?

• Direct formation of shoots

• Formation of embryos from callus

• Formation of embryos without callus

• Formation of callus from roots

What is the role of growth regulators in the multiplication stage?

• To enhance virus activity

• To differentiate callus into shoots or embryos

• To prevent cell division

• To eliminate the need for acclimatization

What is the structure of the shoot tip?

• A flat surface of meristematic cells

• A cluster of roots

• An inverted cup of meristematic cells surrounded by leaf primordia

• A solid mass of differentiated cells

Why do we use apical meristem in plant propagation?

• It is connected to the vascular system

• It has a lower cell division rate

• It is easier to isolate from the plant

• Cell division is higher than viruses

What is somaclonal variation?

• A stage of organogenesis

• A method of acclimatization

• Mutation in tissue culture

• A type of virus

What is the result of the multiplication stage?

• Only leaves

• Only callus

• Shoots and embryos

• Only roots

What is the second stage of micropropagation?

• Rooting

• Establishment

• Acclimatization

• Multiplication
