No change in colour
It turns brown
When the leaf from pot X is tested with iodine at the end of the experiment it.... (Choose the best answer -- hint: soda lime absorbs carbon dioxide from the air.)
turns blue-black because there is no starch in the leaf.
turns blue-black because there is starch in the leaf.
does not show any change in colour because there is starch in the leaf.
does not show any change in colour because there is no starch in the leaf.
The image shows a leaf before (left) and after (right) a starch test was done on it. Before the starch test, part of the leaf was covered with some black paper while it was still growing on a live plant.
Explain why the results turned out like this. (2 answers)
the part covered by the black paper did not receive light.
the part covered by the black paper received more light.
starch was detected at the part covered by the black paper
starch was not detected at the part covered by the black paper
When a starch test is done on this leaf, no change in colour was observed on the yellow parts of the leaf because... (2 answers)
there is starch there
there is no starch there
there is no chlorophyll there for photosynthesis to take place
there is chlorophyll there for photosynthesis to take place
The starch test results of this experiment shows the leaf from plant P turning blue-black while the leaf from plant Q had no changes in colour. Why is this? (2 answers)
There was starch in the leaf from plant P.
There was starch in the leaf from plant Q.
Plant P did not have carbon dioxide to do photosynthesis
Plant Q did not have carbon dioxide to do photosynthesis
