Plant Propagation Ch2

Front 1

5 biological concepts essential for plant propagator

Back 1

1.sexual vs. asexual propagation
2.gene expression and the control of plant growth and development
3.hormonal control of plant growth and development
4.plant life cycles including phase change
5.plant nomenclature and the concept of the cultivar

Front 2

mitosis

Back 2

the active process of cellular division which occurs in meristematic sites such as roots, stems, leaves and cambium

Front 3

six steps leading to formation of seeds

Back 3

1.the formation of stamens and pistils in flower beds
2.the openeing of the flower indicating sexual maturity
3.pollination, the transfer of pollen from an anther,germination of the pollen and formation of the pollen tube
4.fertilization of the egg and polar nuclei from the pollen tube
5.growth of the fertilized egg and differentiation into an embryo plus a surrounding seed coat, the actual seed
6.maturation of the seed with an accumulation of stored food

Front 4

the life cycle of flowering plants and ferns takes place in two alternating biological generations:

Back 4

the sporophytic stage

the gametophyte stage
