DEVELOPMENTAL BIOLOGY
CHAPTER 1 ELABORATED
QUESTIONS AND ANSWERS
Embryo - CORRECT ANSWER-the developing human
organism from about 2 weeks after fertilization through the
second month
Development - CORRECT ANSWER-multicellular organisms
arise by a relatively slow process of progressive change called?
Embryology - CORRECT ANSWER-the study of animal
development
a phase of an organism that exits between fertilization and birth
developmental biology - CORRECT ANSWER-the discipline
that studies embryonic and developmental processes
studies the building of an organims, it is a science of becoming,
a science of process
aristotle - CORRECT ANSWER-the first known embryologist
he said that wonder was the source of knowledge and animal
development
two major objectives of development - CORRECT ANSWER-1.
Generate cellular diversity and order within the individual
organism
2. Ensure the continuity of life from one generation to the next
,two fundamental question in developmental biology -
CORRECT ANSWER-1. How does the fertilized egg give rise
to the adult body
2. How does that adult body produce yet another body
Differentiation - CORRECT ANSWER-process in which cells
become specialized in structure and function
the generation of cellular diversity
The question of morphogenesis - CORRECT ANSWER-How
can the cells in our body organize into functional structures
morphogenesis - CORRECT ANSWER-the creation of ordered
form
involves coordinating cell growth, migration, and cell death
The question of growth - CORRECT ANSWER-how do our
cells know when to stop dividing?
How is cell division so tightly regulated
The question of reproduction - CORRECT ANSWER-How are
these germ cells set apart, and what
are the instructions in the nucleus and
cytoplasm that allow them to form the next
generation?
The question of regeneration - CORRECT ANSWER-how do
stem cells retain their capacity, and can we harness it to cure
debilitating diseases?
the question environmental integration - CORRECT ANSWER-
the sex of many species of turtles is dependent on temp.
, formation of the reproductive system in some insects depends
on bacteria
How is the development of an organism integrated into the
larger context of its habitat?
Evolution - CORRECT ANSWER-involves inherited changes of
development
how do changes in development create new body forms?
which heritable changes are possible, given the constraints
imposed by the necessity of the organism to survive as it
develops?
embryo - CORRECT ANSWER-where genotype is translated
into phenotype, and where inherited genes are expressed to
form the adult
Embryogenesis - CORRECT ANSWER-the stages of
developments between fertilization and hatching
Stages of development - CORRECT ANSWER-Fertilization,
cleavage, gastrulation, Organogenesis, metamorphosis,
gametogenesis
Fertilization - CORRECT ANSWER-fusion of the mature sex
cells (gametes)
initiates development as gamete nuclei fuse
formation of genome
Cleavage - CORRECT ANSWER-series of rapid mitotic
divisions of
