Would one recommend application of a rooting hormone to the type of cutting shown in the diagram?
Yes
Auxin stimulates root initiation, but inhibits shoot initiation.
True
When one pollen sperm cell nucleus (1N) units with the two polar nuclei (2N), the ______ is formed.
Endosperm
Determinate plants form inflorescences at the apical meristems, thus stem growth in height terminates.
True
This hormone may be translocated in both directions. It stimulates stem growth through both cell division and cell elongation.
Gibberellin (GA)
___________ is the process of reducing free water in plant tissues by reducing temperature, humidity, irrigation, and fertilization in order to prepare seedlings grown in a protected environment (such as a greenhouse) for eventual transplanting into garde
Stratification
Scientific nomenclature names plants with a two-word species name given in Latin. This is called the binomial classification system. The first part of the name refers to the plant's _________ and the second part of the name is the __________.
Genus, specific epithet
What techniques would be useful for reducing plant height without chemical PGRs?
2. Restrict availability of nitrogen fertilizers
3. For certain plants, gently brush the tops 1-2 times daily

Corm
_______________ means to make ready for spring, and it is any temperature treatment between 32 F and 50F that induces or promotes flowering in plants.
Vernalization
A pollen tube contains two sperm cell nuclei. When one pollen sperm cell nucleus (1N) unites with the egg cell nucleus, the ______ is formed. When the other pollen sperm cell nucleus (1N) unites with the two polar nuclei (2N), a triploid (3N) nutritive ti
Embryo, endosperm
Apical meristems are located at root tips and are responsible for the growth in length of roots.
True
Subapical meristems are responsible for the stem elongation or bolting of rosetted plants prior to flowering
True
intercalary meristems are located between regions of older tissues, just above the nodes, and are responsible for the elongation of leaf blues in monocots (grasses)
True
Phloem is a complex tissue through which food and metabolites travel from the leaves to the stems, flowers, roots, and storage organs.
True
Indeterminate plants form inflorescences in the leaf axils, and stem growth in height continues until stopped by senescence or environmental influence.
True
Meiosis...
1. Is reductive cell division
2. Produces the haploid
3. Is responsible for gamete production
True statements about plant hormones
1 naturally occurring chemical
2 produced in and active in minute quantities
3 produced in plant distant from site of action
4 some have an inhibitory effect on plant growth and development
PGRs can include both hormones and synthetic chemicals.
True
The plumule is the embryonic shoot
True
The radicle is the embryonic root
True
Should one recommend application of a rooting hormone to a leaf petiole cutting?
NO
One horticulture use for in vitro culture is pAthogen elimination from heat-induced meristems
True
In lAyering, the part to be rooted is left attached to the mother plant, from which it receives water and nutrients while rooting.
True
Asexual or vegetative propagation is accomplished through mitosis cell division.
True
