The part of the leaves that cover with the black paper will change color to yellow or weakness and for many week this leaves will die.
We did this experiment and honestly didn't notice much of a difference in the leaves. I think what is supposed to happen is that the leaf should start to lose it's green color and wilt because it cannot photosynthesize.
With the help of Ganongs' respirometer, the green leaves will be put in the bulb of the apparatus covered by black paper to cut off light and then after the experiment the gas evolved will be tested for CO2. If it gives the test for CO2, it is prooved that green plants respire.
The half of the leaf covered with black construction paper would not be able to photosynthesize, as it would not receive any sunlight. The uncovered half of the leaf would continue to photosynthesize, but the overall productivity of the leaf would be reduced.
The leaf will continue to photosynthesize and produce glucose through sunlight exposure. However, the portion covered with black paper or cloth will not undergo photosynthesis due to lack of light. This difference in light exposure will likely result in varying levels of glucose production and overall health between the covered and uncovered parts of the leaf.
A snow-covered field would reflect the highest percentage of the sun's energy back into space as snow has a high albedo, meaning it reflects a large portion of sunlight. The black asphalt roadway, tarmac runway, and roof covered in black tar paper would absorb more sunlight due to their dark colors and have lower albedo, reflecting less energy back into space.
The can covered with black paper will heat up faster than the one covered with white paper. This is because black paper absorbs more light and heat energy compared to white paper, which reflects light.
In black and white -- on paper... everything moves on paper and leaves behind a paper trail. Sometimes there is a paper jam....
When a leaf is covered with black paper, it cannot receive sunlight, which is necessary for photosynthesis. Without sunlight, the chlorophyll in the leaf breaks down and the leaf turns black due to the accumulation of other pigments such as anthocyanins and carotenoids.

Graphite leaves a streak on paper, as it is the material commonly found in pencils. The black mark left on paper is due to the graphite particles rubbing off onto the surface.

The black paper absorbs heat and raises the temperature, causing the leaf to dry out and wilt due to excessive loss of moisture through transpiration. With prolonged exposure, the leaf may eventually die as it is deprived of sunlight for photosynthesis and becomes overheated.
If you shine red light on black paper, the black paper will absorb most of the red light and appear dark. The red light that is not absorbed may be reflected or scattered, but it will not significantly change the appearance of the black paper.
The black paper absorbs more sunlight, causing it to heat up and melt the snow underneath. The white paper reflects more sunlight, staying cool and preventing the snow beneath it from melting as quickly. This creates a contrast where the black paper leaves a dark spot and the white paper leaves a lighter spot on the snow.
It gets very soggy
