Effect of extreme cold and extreme hot weather on plants?

Answer 1

Increased temperature will increase the rate of chemical reactions within the plant. This will mean the plant will need more oxygen, carbon dioxide and water supplied. If it is hot and subsequently dry the plant will reduce water loss by closing stomata slowing normal processes. This works to a limited extent whereby signs of water loss such as wilting occur.

Cold itself mostly just slows processes. Unless the plant is in its reproductive phase. Cold due to ice can depend on how the plant is adapted and how the ice settles. (A covering of ice over a bud can actually protect it from cold temperatures.) If it is sufficiently cold the water within the plant can freeze, causing the cells to expand and break. This could cause death.

Source(s):You can research the rest, it can be interesting if you find the right texts. There is a lot of information on temperature, and it is an area of interest presently with concerns about climate change.

Answer 4

Cold temperatures may harm the plant, killing its cells. The plant may droop and die within several days. Plants grow best in room-temperature, with the amount of water and sunlight it needs daily. Do not put a plant in coldness.

Answer 5

Extreme cold on most plants results in frost burns (or a condition known as Black Frost). This occurs when water in the cells of the plants freezes, it forms crystals and expands as it freezes, this ruptures the cell walls causing the cells to die.

Obviuosly not all plants are affected by this - deciduous plants have mechanisms in place to reduce or negate the effect of frost and snow (as do some evergreens such as pines).

Answer 6

Extreme cold and hot weather effects plants in a negative way. This is because the organelles in the plants can not function in extreme cold and hot temperatures.

Answer 7

It depends on what plant, how hot or how cold the temp is.

Answer 8

Extreme Cold- It will freeze to death, if you don't put it near something warm. Extreme Hotness- If you don't give it a lot of water, it will die, because of the heat.
