Botany Chapter 11 Review questions with
verified answers
5 types of plant hormones Ans✓✓✓auxin, cytokinins, gibberellins,
abscisic acid, ethylene
day-neutral plants Ans✓✓✓plants whose flowering cycle is not
sensitive to periods of light and dark
development in cells definition Ans✓✓✓coordination of growth and
differentiation of a single cell into multicellular tissues and organs
Difference between phototropism and photoperiodism
Ans✓✓✓phototropism is a directional response causing plants to
respond to particular stimulis so they grow towards or away from it
(mostly); while photoperiodism is a regulatory process which causes
regulation of development (of particular plants) based on day/night
cycles
Differentiation Ans✓✓✓Cells develop different forms adapted to
specific functions (such as conduction, support, secretion, etc.)
Every plant growth response results from a series of biochemical steps
called a Ans✓✓✓signal transduction pathway
gravitropism Ans✓✓✓A growth response to gravity
, growth biological definition Ans✓✓✓irreversible increase in mass due
to the division and enlargement of cells
intermediate day plants Ans✓✓✓This kind of plant flowers when as
long as the number of hours in darkness is neither too great nor too few
(These are plants native to tropical regions).
Lack of nutrients restricts what? Ans✓✓✓normal development of
plants
long day plants Ans✓✓✓plants that will not flower unless periods of
light are longer than the critical length (eg nights are shorter)
nastic movement Ans✓✓✓A plant's response to a stimulus such that the
direction of the response is preprogrammed and not dependent on the
direction of the stimulus
negative tropism Ans✓✓✓when plant grows away from a stimulus
Nutrients Ans✓✓✓furnish the elements and energy for plant growth
and maintenance
photoperiodism Ans✓✓✓A plant's response to seasonal changes in
length of night and day (ex: plant doesnt bloom during increased
wintertime darkness)
