Introduction

Plant Growth may be defined as an increase in size, morphology and weight

• Growth means increase in cell number, size, and developmental differentiation
• Growth involves an increase in dry mass, duplication of protoplasm, cell multiplication, and a permanent increase in volume
• Growth is a process in which the organism passes in orderly stages of development through time and the internals necessary to encompass the various critical stages
• Growth , development, and differentiation in the plant is the outcome of highly organized and specialized physiological process which are guided by the growth substances to bring change
• Growth is the permanent and irreversible increase in volume and weight about by cell division, cell elongation and increase in protoplast
• Increase of organic matter or formation of new protoplasm is basis to the phenomenon of growth
• The increase in size or volume due to growth should not be confused with the temporary increase in size and volume of certain organs due to imbibition of water
• Growth is a quantitative term, related only to changes in size and mass
• For cells, growth is simply an irreversible increase in volume
• For tissues and organs, growth normally reflects an increase in both cell number and cell size
