what is a clone
identical copy of a cell
what is a spore
structure released by a sporangium during asexual reproduction
what is budding
when bud forms on parent in asexual reproduction
what is the cell cycle
series of events that make up the life cycle of a cell
what is binary fission
when the parent cell splits into two during asexual reproduction
what is vegetative propagation
when plants grow from parts of their roots, stems or leaves in asexual reproduction
what do all asexual reproductive processes have in common
all require one parent only, 100% dna passing, genetically identical daughter cells..
what is splitting
a plant is split into 2/more pieces and each contains shoots and roots
grafting?
bud/portion of root/stem part is cut from one plant and joined to another
cutting?
cut a part of leaf/stem/root and put in water w nutrients and cells near cut will develop into roots/shoots
simple layering?
section of stem bent to touch ground and cut is made to promote root growth and is cut away from parent plant once formed
air layering?
strip of outer bark removed and moss around and plastic around allat and then is cut away from parent once new root develop
tissue culture?
when individual cell/small piece of plant is placed in or on nutrients to promote root/sh growth and tiny plantlrts develop to put in soil
