today's the start of the race. officially.biology practical.
qn 1. osmosis & mean change in length. onion was the plant given. it was not tt difficult, just tt i had to manipulate the results to make sense out of it. plus, there's this qn which i think is pretty ambiguous. 3 marks..i just put down what i thought was right..n i made a silly mistake here, which costed me 2 marks.
no qualms about that.
qn 2. 2 specimens of leaves are given. one of them is a variegated leaf, & u are asked to test for starch. the other is a normal one, & u are asked to test for reducing sugar. then u are supposed to draw a plant cell and label it. i go gl and put 2 vacuoles, thinking i shld follow the diagram given. hope i won be penalised for that. then planning for expt.
yeah. tt's all. hope i can do well..
hmm. have to pack my stuff, and get ready for the big 'race' tmr. yeah. cya.
silly haze. down with flu.
