QUESTIONS WITH COMPLETE
SOLUTIONS
In this transport route, water and solutes move along the continuum of cell walls and
extracellular spaces - ANSWER-apoplastic
The physical property that predicts the direction in which water will flow. - ANSWER-
water potential
This barrier prevents water and minerals from crossing the endodermis and entering
the vascular cylinder via the apoplast. - ANSWER-Casparian strip
The process responsible for the loss of water vapor from the leaves of a plant. -
ANSWER-transpiration
About 95% of the water a plant loses escapes through these. - ANSWER-stomata
Each microsporocyte undergoes meiosis forming four haploid ________. -
ANSWER-microspores
The large diploid cell within the mega sporangium that divides by meiosis to produce
the megaspore. - ANSWER-mega sporocyte
Fertilization of the two polar nuclei forms a triploid cell that develops into nutritive
tissue called. - ANSWER-endosperm
This process ensures that endosperm develops only in ovules where the egg has
been fertilized. - ANSWER-double fertilization
A growth response in which plant organs curve toward or away from stimuli is called.
- ANSWER-tropism
In signal transduction pathways, these small molecules and ions amplify the signal. -
ANSWER-second messengers
The chief function of this hormone is to stimulate elongation of cells within young
developing shoots. - ANSWER-auxin
This hormone, in addition to promoting fruit development, will cause seeds to break
dormancy and germinate. - ANSWER-gibberellins
When a plant begins to wilt, this hormone accumulates in the leaves and causes the
stomata to rapidly close. - ANSWER-abscisic acid
In response to this gaseous plant hormone, germinating pea seedlings grown in the
dark undergo the triple response. - ANSWER-ethylene
, "Simple squamous" is a description that applies to this type of animal tissue. -
ANSWER-epithelial tissue
The study of the biological form of an animal. - ANSWER-anatomy
Has a matrix that consists of fibers in a liquid, jelly-like or solid foundation. -
ANSWER-connective tissue
Consists of spindle-shaped fibers responsible for involuntary movements. -
ANSWER-smooth muscle
Allows its internal condition to vary with certain external changes. - ANSWER-
conformer
Transfer of heat between fluids flowing in opposite directions. - ANSWER-counter
current exchange
Ectoprocts, Phoronids and Brachiopods are grouped together because they all
posses this - ANSWER-lophophore
A type of asexual reproduction in which females produce more females from
unfertilized eggs. - ANSWER-parthenogenesis
Members of this worm phylum have a well-developed coelom that is partitioned by
septa. - ANSWER-Annelida
Unique to this invertebrate phylum is a network of hydraulic canals that branch out
into tube feet. - ANSWER-Echinodermata
Chordates that have a head but lack a backbone. - ANSWER-craniates
Members of this phylum have a skeleton composed predominantly of cartilage. -
ANSWER-Chondricthyans
This clade of amniotes was the first to adopt a completely terrestrial life style. -
ANSWER-reptiles
This derived chordate character first served as a suspension feeding device and was
later modified for gas exchange in non-tetrapod vertebrates. - ANSWER-pharyngeal
slits
These structures found near the tips of a plant's roots increase absorptive surface
area. - ANSWER-root hairs
The inhibition of axillary buds by an apical bud. - ANSWER-apical dominance
This vascular tissue transports sugars from source to sink. - ANSWER-phloem
The perpetually undifferentiated tissues of plants. - ANSWER-meristems
