Thermoregulation

A detailed Summary of Thermoregulation

It is hard to believe that some plants produce as much heat for their weight as birds do, which are the greatest heat producers

of all. It is even harder to believe that some are able to thermoregulate, which means that they actually alter their heat

production to keep their temperature constant in fluctuating air temperatures. This is similar to what mammals do. The

article I am reviewing tells about few a plants that do this, and how they do it.

There are only three plants which have yet been shown to regulate their temperature. They are the Philodendron selloun, the

Skunk Cabbage, and the Sacred Lotus. The most extensive testing has been done on the P. selloun. The earliest testing aimed

to do little more than determine whether the inflorescence actually had become hot. In the experiment spadices were impaled

with temperature probes into the plant and the probes were connected t

o a machine that recorded the temperature

energy to keep warm. So those that land on thermogenic flowers would receive a fairly steady level of heat from the plant.

protect parts from damage if heat production was uncontrolled.

Then the inflorescences were examined at air temperatures from low freezing to temperatures that are uncomfortably hot

explain why heat production is raised and lowered to keep the plant temperature in a certain range. There are two other
