Plant Reproduction and Signaling

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

• Stimulates cell division, elongation in stems

What is the definition of flowers in plants?

• The reproductive structure of angiosperms.

• 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 arrival of pollen on a stigma or other pollen-receiving reproductive part of a seed plant.

What is the process of asexual reproduction of angiosperms?

• 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.

• The growth of new roots and shoots from extensions or fragments of a parent plant.

• The reproductive structure of angiosperms.

What is the difference between monocot and dicot?

• The number of seed leaves in the embryo

• The development from an embryo (seed) into a mature plant.

• The reproductive structure of angiosperms.

• The arrival of pollen on a stigma or other pollen-receiving reproductive part of a seed plant.
