9.3 Growth in plants
- NATURE OF SCIENCE
- Developments in scientific
research follow improvement
sin analysis and deduction
- Improvements in analytical
techniques allowing the detection of
trace amounts of substances has led
to advances in the understanding of
plant hormones and their effect on
gene expression

- MERISTEMS
- Undifferentiated cells in the
meristems of plants allow
indeterminate growth
- Mitosis and cell division in the
shoot apex provide cells needed
for extension of the stem and
development of leaves

- Undifferentiated cells in the

- PLANT HORMONES
- Control growth in
the shoot apex
- Plant shoots respond
to the environment by
tropisms
- Micropropagation of plants
using tissue from the shoot
apex, nutrient agar gels and
growth hormones
- Use of micropropagation
for rapid bulking up of
new varieties
- Production of virus-free
strains of existing varieties
- Propagation of orchids
and other rare species
- Used for rapid bulking up
of new varieties of plant
- Use of micropropagation
for rapid bulking up of
new varieties
- Plant shoots respond
to the environment by
tropisms
- Auxin
- Auxin efflux pumps can st
up concentration gradients
of auxin in plant tissues
- Auxin influences cell growth
rates by changing the pattern
of gene expression
- Auxin efflux pumps can st
up concentration gradients
of auxin in plant tissues
- Control growth in
the shoot apex
- TOK
- Plants communicate chemically
both internally and externally
- To what extent can plants
be said to have language?
