What is germination?
The reproductive structure of angiosperms.
The growth of new roots and shoots from extensions or fragments of a parent plant.
The development from an embryo (seed) into a mature plant.
The arrival of pollen on a stigma or other pollen-receiving reproductive part of a seed plant.
What is the function of auxin in plants?
Stimulates cell division, elongation in stems
Promotes growth by cell enlargement
Stimulates formation of roots on a shoot
What is the role of gibberellin in plants?
Promotes growth by cell enlargement
Stimulates division of shoot apical meristem cells
Stimulates cell division, elongation in stems
gibberellin stimulates expansion along the long axis of a plant organ
What is the function of abscisic acid in plants?
Delays germination
Promotes growth by cell enlargement
Promotes apical dominance
Stimulates cell division, elongation in stems
What is the definition of pollination?
The arrival of pollen on a stigma or other pollen-receiving reproductive part of a seed plant.
The development from an embryo (seed) into a mature plant.
The growth of new roots and shoots from extensions or fragments of a parent plant.
The fusion of the ovum and pollen grain to create an embryo
What is the function of cytokinin in plants?
Stimulates cell division, elongation in stems
Stimulates division of shoot lateral meristem cells
Stimulates division of shoot apical meristem cells
Coordinates effects of other plant hormones during development of shoots and roots
What is the role of ethylene in plants?
Promotes growth by cell enlargement
Stimulates flowering in some plants
Part of regulatory pathways that govern a wide range of metabolic and developmental processes
