INTRODUCTION to Developmental Biology Flashcards
A branch of biology that
focuses on understanding
how organisms grow and
develop from a single cell
to a complex, multicellular
organism.
Developmental Biology
Developmental Biology is a branch of biology that
focuses on understanding
how organisms _____________.
grow and
develop from a single cell
to a complex, multicellular
organism.
6 Key Concepts of Developmental Biology
- Gametogenesis
- Fertilization
- Embryogenesis
- Differentiation
- Gene Regulation
- Maturation
6 Basis of Developmental Biology
- Anatomy
- Physiology
- Cell Biology
- Molecular Biology
- Genetics
- Biochemistry
is a branch of science that deals with the
study of formation and development of an organism.
EMBRYOLOGY
involves fusion of male and
female gametes to produce an offspring.
Sexual Reproduction
is a branch of science that deals with
complete life cycle (prenatal and postnatal growth and
development) of an organism
ONTOGENY
deals with an evolutionary history and
relationship among organisms.
PHYLOGENY
Phylogenetically, organisms are classified into 5
✓Fishes
✓Amphibians
✓Reptiles
✓Birds
✓Mammals
is a broad term that involves transformation
of a simple single cell into a complex multicellular organism
that involves growth and differentiation.
DEVELOPMENT
Mere increase in the number and size of cells
GROWTH
3 types of Growth
- Multiplicative Growth
- Auxetic Growth
- Accretionary Growth
A type of Growth where it is an increase in cell
number by cell division.
Multiplicative Growth
A type of growth which it is an increase in cell size.
Auxetic Growth
A type of growth which it is an increase in intracellular
substances.
Accretionary Growth
