Terms 1
The study of how an organism functions.
What is physiology?
Transfer of pollen from a stamen to a pistil.
What is pollination?
A plant that lives for one growing season.
What is an annual?
A short term resting state in seeds where growth of the embryo is suspended.
What is quiescence?
The process of aging that leads to death.
What is senescence?
The movement of a solute due to osmotic pressure from a source to a sink.
What is pressure-flow?
The process by which a seed develops into a seedling.
What is germination?
A plant that lives for multiple growing seasons.
What is a perennial?
This type of tropism is displayed by a plant growing straight while being surrounded by light.
What is gravitropism?
The state in which normal physical functions are suspended or slowed down.
What is dormancy?
Asexual reproduction in plants in which a new plant grows from a fragment of the parent plant.
What is vegetative reproduction?
The response of an organism to seasonal changes in day length.
What is photoperiodism?
A plant that lives for two growing seasons, flowering in the second one.
What is a biennial?
If transpiration increases, one would expect this to happen to the way water and minerals flow in the xylem.
What is increase? (more water and minerals)
In flowering plants, when a pollen grain lands on this structure of a pistil, the tube nucleus forms a pollen tube that goes down to the embryo sac, or female gametophyte.
What is the stigma?
Photoreceptors in bacteria, protists, fungi, and plants that are responsible for detecting red light and far-red light.
What are phytochromes?
Photoreceptors in bacteria, animals, and plants that detect blue and ultraviolet light and contribute to the circadian rhythms that result.
What are cryptochromes?
The response of a plant to an environmental stimulus whereby roots, stem, or leaves move toward or away from the stimulus.
What is tropism?
This microscopic organism is responsible for nitrate being formed in the soil.
What is bacteria?
If material in the phloem is traveling up from the roots of a deciduous tree, one would conclude that the tree's leaves would not be performing this common function of plants at this time.
What is photosynthesis?
What is abscission?
The response of a plant to changing temperatures during the changing season.
What is thermoperiodism?
The influence of the shoot tip to inhibit the growth of lateral buds, reducing branching.
What is apical dominance?
These are the five major categories of phytohormones.
What are auxins, gibberellins, cytokinins, abscisic acid, and ethylene?
This part of the plant embryo develops into structures that allow the plant to make food for itself once the endosperm is used up.
What is the plumule?
