Answer 1

Answer:

ans = Light is one of the required for photosynthesis . when a part of the leaf is covered from both upper and lower sides with a black paper strip, light .

Answer 2

Explanation:

As the part of the leaf is covered with a black strip, it will not absorb any sunlight. In rest of the part of the leaf being exposed to the sunlight, will perform photosynthesis and therefore produce starch.

If the plant's leaves are covered with black paper the imp process for the life of plant i.e. photosynthesis will not occur in that area (leaves). If all the leaves are covered as such then the plant will ultimately go to senescence i.e. death.
