Flashcards: PLANT REPRODUCTION
Sexual Reproduction
need two parents
Asexual reproduction
only needs one parent creates genetically identical offspring
Binary fission
form of asexual reproduction in which an organism divides in two
Budding
new organism develops from an outgrowth of another one (Asexual)
Vegetative propagation
A form of asexual reproduction
Runners
long side shoots that eventually produce new plants (Asexual)
Leaves
young plants on the leaves which grow into new plants if they fall off
Rhizomes
underground stems that develop into new plants
Suckers
new stem grows from the base of an old one
Bulb
lateral buds which may grow into new plants
Tuber
swollen underground stems which grow into new plants
Corm
one or more internodes with at least one growing point
Grafting
plant attached to base of another plant
Stock
the plant onto which another plant will be attached
Cuttings
stem is cut from a plant and replanted
Tissue culture
The growth of a new plant in a cultured medium
Regular
plant may be cut longitudinally in any plane to give two halves
Calyx
made up of four sepals
Stamen
male reproductive structure
Anther
holds pollen
Filament
holds up the anther
Pistil
female reproductive structure
Style
passage for the pollen tube
Stigma
sticky landing place for pollen
Bilocular
refers to the two chambered ovary
Pollination
the transfer of pollen grains from the anther to the stigma of a flower
Self
fertilization - pollination occurs between flowers of the same plant
Cross
pollination - pollination between flowers of different plants
Coevolution
mutual evolutionary influence between two species
Cotyledons
reserve food storage
Spermophytes
all seed bearing plants
Seedbank
stores seeds to preserve genetic diversity
Polyploidy
common technique to overcome sterility
