Introduction Flashcards
is an irreversible increase in mass, or volume of a living organism, organ or cell
growth
stages of cellular growth
- cell division
- cell enlargement
- cell differentiation
the number of cells increase due to mitosis
cell division
the size of individual cell increases after cell division due to increase in the volume of its protoplasm
cell enlargement
structure of the cells changes to perform specific functions
cell differentiation
types of growth
- determinate growth
- interdeterminate growth
plant growth in which it grows to certain size and then stop growing due to presence of terminal influorescence
determinate growth
plant growth in which the main stem continues to elongate indefinitely without being limited by a terminal in fluorescence or other reproductive structure
indeterminate growth
three phases of growth curve
- log phase
- lag phase
- senescence period
measurement of growth
- increase in length or growth
- increase in area or volume
growth can be measured by a variety of parameters as follows:
- fresh weight
- dry weight
- length
- area
relate to varying degrees of expansion or growth in weight of an organ
development
