12. A student investigated the conditions that plants need for photosynthesis. The leaves of the plant he used had green and white parts.
Diagram 1 shows how part of one leaf was covered in black (opaque) card.The plant was placed in a warm, sunny area and was watered well. Eight hours later the leaf was removed from the plant and was tested for starch.
The results of the test are shown in Diagram 2, the shaded parts show where starch was present.
i. Why was no starch found in the part of the leaf labelled A
ii. Why was no starch found in the part labelled B.
13. Give two conditions necessary for photosynthesis apart from a suitable temperature range and the availability of water and carbon dioxide.
