Development of any complex multicellular organism results from growth processes: Mitosis and cell enlargement and developmental processes f cell differentiation.
In plans, these processes begin from with activities of the meristems….
Growth: increase in size (volume and biomass)
- limited by the supply of resources that are responsible for cell enlargement and division
Development: Changes in form occurring from embryonic stage to adult stages
- under a control of genes directing hormone production, chemicals regulating growth and development
Plants require: water, light, CO2 to make energy-rich sugars and oxygen for cellular respiration
Plants also require mineral nutrients: all essential and lacking them = growth deficiency
- get them from their environment (usually the soil)
Macronutrients: needed in large amounts: Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, and Sulfur
Micronutrients: needed in small amts: Iron, Zinc, Boron, Copper, Manganese, Chlorine, Molybdenum
Lacking particular nutrients = specific growth deficiency
