-discuss the use of hormones in food production

-compare the role of transpiration and
translocation in the transport of materials from
sources to sinks, within plants at different
seasons


i dont get the first point and the underlined part....

would appreciate some help!

The plant growth hormone auxin, can be sprayed onto flowers to encourage fruit
development, even when pollination has not occurred. Auxins are also used in
weedkillers. They kill broad?leaved plants so monocotyledonous crop plants are not
affected, and have less competition. Some plant hormones can encourage root and
shoot formation, in tissue samples taken from food plants in a process called tissue
culture. Plant hormones are also used to produce seedless fruits, to promote seed
germination, to delay ripening so that fruit can be transported, to increase yield,
and to produce short stems to reduce wind damage.
In animals hormones can be used to increase milk production, and growth hormones and testosterone are used to increase meat production.

this is it.

Transpiration helps cool the plant(as water evaporates it takes away the heat)This helps during summer.(i guess this is what it means when it says different seasons)
Translocation involves transporting substances from the site of production to sites of storage and growth. e.g. glucose from leaves to rest of the plants for growth and storage(e.g tubers in potato plants)

whats the function of the pancreatic juice?

It contains
a) Trypsin converts proteins to peptides and peptides to soluble amino acids
b) amylas converts starch to maltose
c) Lipase convert and break fats into 3 fatty acids & glycerol
i hope i helped
