He entered it wrong.
Armap, what is the world coming to?
...We even have individuals imposing their geological beliefs onto forms of biology. They even go so far as to find geological formations that are
reminiscent of the Martian trees, which they then use to orchestrate an argument based upon logical fallacy - a tactic known as a 'strawman'
argument.
What's worse is their tendency publish their geology-bound interpretations in journals which do not believe in or acknowledge martian biology
(despite all evidence to the contrary); therefore, it is biased and one-sided, and hardly representative of truly critical peer review.
Here is an image of some Liquid Water on Mars and a quote from a NASA scientist about it:
“These observations give the strongest evidence to date that water still flows occasionally on the surface of Mars,” said Michael Meyer, lead
scientist for NASA’s Mars Exploration Program, Washington.
*Above the ground there is C02 (plant food) and there is liquid water underground (which is where trees get most of their water...). Even the climate
on Mars does not preclude such life.
Some plants produce chemicals that act like antifreeze. The chemicals lower the temperature at which the water will freeze.
Another method plants use to avoid freezing has been discovered by botanists at Cornell University:
"As the temperature drops, this water freezes, but the other molecules are not included in the ice crystals. As the concentration of these other
molecules increases, water inside the plant cells is drawn out by osmosis. This process continues until the cells in a plant bud are almost totally
dehydrated. If there is no water in the bud, the bud can freeze without damage. In the spring when the temperature rises, water is drawn back into the
bud and the cells revive. Where we live, in the early fall you see plants covered with what is called rime."
A more active fluid exchange system would also prevent freezing to the above ground portion a a plant on the Martian surface. The large amount of c02
in the Martian atmosphere would also facilitate/support a more active plant biology and the reduction of light for available photosynthesis would be
augmented by a more active fluid exchange system.
