Millions of years already but animals and plants are still far away to be similar. Plants and animals have different kinds of cells, locomotion, way of getting food, the air that they breath, the senses, the general structure and inner system. They don’t have a very complex structures unlike some animals which have hearts, stomachs and etc. Plants are known to be one of the lowest stages in the food pyramid (except if it’s a carnivorous plant which eats insects). However, there are some conditions of plants that can also be the same to animals, especially to humans.
Plant Cancer
For animals, cancer can occur when a tumor grows which is the effect of the cells in their body losing the control of its normal development. This phenomenon can also happen to plants. However, the difference is that plants are not greatly harmed with this condition compared to animals and especially humans. This is because cells are being contained in “cell dividers” which prevents it from spreading into the other vital parts of the plants. It can still live without that infected part unlike humans who can’t breath properly if the lungs catch the condition.
Plant Fever
According to a researcher, plants can catch fever which results to high temperature. However, in other sense, it’s not as the same way as animals. Although, the cause can be similar to a virus. Especially plants of the Araceae family can show signs of fever by rising of their body temperature.But it’s not because they are sick but because they want to maintain the warmness and coldness of their flowers. There could be a lot of reasons why these plants do this. But commonly, they do it because of the pollen to keep it dry or because of the odor to attract pollinators.
