10.1 Growth Phases
Definition of Growth
- any permanent increase in qualitative parameters (can be measured) e.g volume, width, length (height), cell number, dry mass, surface areas
- which is not reversible
- an increse in biomass, length and width over a specific time
Definition of Development
- any qualitative changes e.g function, degree of specialization and complexity
- involve cell differentiation, e.g red blood cell and xylem
- is restrictive by the size of its cytoplasm that is controlled by its nucleus
- when achieve a certain size, it divides to produce 2 daughter cells of smaller size
