The natural blind spot is due to lack of receptors where the optic nerve and blood vessels leave the eye. There can also be artificial blind spots when something blocks light from reaching the photoreceptors, or when there is local adaptation of the retina as just after seeing a bright light
The answer is cell organelles.
The answer is the leaf in flask B will not get carbon dioxide to make glucose. The leaf does not get the carbon dioxide as this is absorbed by potassium hydroxide solution, resulting to the absence of glucose made by the process of photosynthesis. Plants use the energy of sunlight to convert carbon dioxide and water into glucose, hence photosynthesis would not occur when carbon dioxide is not available.
