It will keep insects away. Many people put plastic bags around their fruit, still on the tree, to guard against fruit fly, parrots, other birds and flying foxes (fruit bats).
It 'expires.' The leaf becomes brown and dry within a weak thin layer called the 'terhomos.' This is the part of the leaf collects sun energy. As the leaf is in the plastic bag, the sun energy will not be able to be received by the leaf.
When a leaf is covered in a plastic bag, the air trapped within the bag becomes enriched with carbon dioxide as the leaf undergoes photosynthesis. This increased carbon dioxide concentration can enhance the rate of photosynthesis, but if the bag is left on for too long, the lack of oxygen could eventually lead to the leaf's death.
it wouldn't make any affect, we think, and it would just stick to the plastic bag!
It gets stretched.
the plastic bag will get get stuck in its oesophagus and if its large enough to choke the cow it will leave the planet.
How long can turtles live in plastic bags? Hmmm? Let me see? They can't live in a plastic bag very long or else they would die.
It will mold!
Covering a leaf with a plastic bag would prevent the exchange of carbon dioxide and oxygen with the atmosphere, limiting the leaf's ability to photosynthesize and reduce carbon dioxide. However, extended lack of gas exchange could harm the leaf's health and eventually lead to a decrease in photosynthetic activity.
sets on fire
you stop breathing.
The branch will die.
in the plastic bag first
