Allometry
different parts must grow at different rates
1 of 10
Determinants
agents differentially inherited at each cell division that make cells different from each other
2 of 10
Willhelm Roux frog's egg
each cell of the two-cell embryo carries a different potential cell fate, one for the left and one for the right half of the embryo
3 of 10
Hans Driesch and the sea urchin
both cells of the two-cell embryo carry potential to develop into normal embryo, depends upon which early cells you separate, fertilised egg has uneven distribution of cytoplasmic determinant
4 of 10
Hans Spemann, Hilde Mangold, newt embryos
all cells of the 16-cell embryo can develop into a normal embryo, transplanted tissues induced the host cells around it to act as if they were dorsal cells, cells communicate to co-ordinate their individual behaviours
5 of 10
Cell adhesion
cells isolated from different tissue layers separate from each other when cultured together, cell surface must contain determinants that mediate this process
6 of 10
Gastrulation
the process common to all animal embryos which generates the three tissue layers
7 of 10
Convergent extension
driven by individual cell behaviour
8 of 10
Plasmodesmata
plant cells are connected to their neighbours
9 of 10
Tissue morphology (shaping)
arises from regulation of cell division and elongation
