in a destarched plant is the plant free from starch or the leaves?
A plant has leaves that are partly green and partly white. The plant is destarched and a leaf is partly covered by black paper.
The plant is placed in bright light for several hours. Four discs are then cut from the leaf in the positions shown and are tested for starch.
Which discs contain starch?
A plant is kept in a dark cupboard for about 48 hours before conducting any experiment on photosynthesis in order to
(a) remove chlorophyll from the leaves.
(b) remove starch from the leaves.
(c) ensure that no photosynthesis occurred.
(d) ensure that the leaves are free from starch.
