K.C.S.E Biology Q & A - MODEL 2001PP1QN15

The diagram below represents a set up to investigate the conditions necessary for seed germination.

The set up was left for 7 days
(a) What conditions were being investigated in the experiment?
(b) State three reasons for soaking seeds in set ups A and B
(c) What were the expected results after seven days?

answers

(a) water, temperature moisture (Acc. Warmth)
(b) Mobilize/ hydrolyze stored food/ active enzymes/ breaking of dormancy softening the testa / seed coat ( acc. As a solvent/ transport media.)
(c) Setup A – those in set up A will germinate
Setup B- those in set  up B will not germinate
Setup C- those in set C will not germinate
