Effect of exterme cold and extreme hot weather on the plants information
Answers
Explanation:
Generally, plants grow faster with increasing air temperatures up to a point. Extreme heat will slow growth and also increase moisture loss. The temperatures for optimal growth vary with the type of plant.Extremely hot or cold soil temperatures can also hamper plant growth, as well as affect seed germination.
All conditions experienced by a plant affect its health and hardiness. ... In this way, so too can weather conditions cause damage to plant vitality. Cold freezes the cells in a plant, causing damage and interrupts the pathways for nutrients and water to flow.
Temperature affects germination in three primary ways: moisture, hormone production, and enzyme activity. For seeds to germinate, they need to imbibe water. For this to occur, sufficient moisture must be present. A warmer climate may increase evaporation and decrease moisture, which would negatively affect germination.
Answer:
Cold also affects plants badly if there is too much low temperature the water in plants start freezing results into the burst of plant cells. Bursting of plantcells cause plants in browning, wilt and eventually death. Increased temperature will increase the rate of chemical reactions within the plant.
