Mystery of germination 1

What is the initial event that commences the germination of a seed?

• Cell expansion

• Appearance of the embryo

• Uptake of water

• Emergence of the radicle

When is the seed regarded as having germinated?

• When cell expansion begins

• When water uptake is complete

• When the embryo appears

• When the radicle emerges

What is the practical indication of establishment in an agronomical sense?

• Cellular and molecular events

• Seedling growth

• Seedling emergence from the soil

• Water uptake by the seed

What is the time course of water uptake by a germinating seed used to depict?

• Seedling growth

• Progress of germination

• Cell expansion

• Resumption of metabolic events

What is the subject of debate regarding the utilization of components during germination?

• Resumption of cell division

• Resumption of DNA synthesis

• Resumption of protein synthesis

• Resumption of RNA synthesis

What is the early priority in the repair and replacement of damaged organelles during germination?

• Repair of DNA

• Repair of RNA

• Repair of mitochondria

• Repair of cell membranes

What is the region responsible for the initial emergence of the embryo in Arabidopsis seeds?

• Radicle

• Transition zone

• Lower hypocotyl

• Cotyledons

What is the major limiting tissue for a considerable number of seeds during germination?

• Radicle

• Testa

• Endosperm

• Perisperm

What is the additional barrier that must be overcome for germination to be completed in some seeds?

• Cell expansion

• Uptake of water

• Restraint imposed by surrounding structures

• Resumption of metabolic events

What is the hormone-mediated induction of wall-weakening enzymes in the limiting tissues aimed at during germination?

• Increase in growth potential

• Reduction of impenetrability

• Resumption of protein synthesis

• Resumption of DNA synthesis
