Questions of Developmental Biology
Multicellular organisms arise by a slow process of progressive change that we call
development
. What are the two major
objectives
of development? What
questions
do biologists have about this process?
Objectives
generating cellular
diversity
and
order
within an individual organism
ensuring the
continuity
of life from
one generation to the next :family:
Questions
morphogenesis
:black_square_for_stop:
how the “shape” of the body is formed
differentiation
the process by which cells become
specialized
in order to perform specific functions within an organism
differentiated cells are
not
randomly distributed
How can the cells in our body organize
into functional structures?
How can a single fertilized egg cell generate so many different cell types?
environmental integration
cues (e.g. Tº :turtle:), chemicals
How is the development of an organism integrated with the larger context of its habitat?
regeneration
stem cells that are able to form new structures even in adults
How do stem cells retain this regenerative capacity?
growth
tightly regulated
How do our cells know when to stop dividing?
reproduction
sperm & egg highly specialized
How are germ cells set apart, and what are the instructions in the nucleus and cytoplasm that allow them to form the next generation?
evolution
inherited
changes of development
How do changes in development create new body forms?
