Question

У большинства растений, произростающих в зоне умеренного климата фотосинтез зимой не происходит. Объясните почему?

Answer 1

 Мороз так скажем паралезует сокодвижение и фотосинтез приостанавливается

Answer 2

Потому что зимой нет сокодвижения. Ведь "зона умеренного климата" подразумевает мороз зимой. А для фотосинтеза как минимум необходима вода. Жидкая.
А яркого солнышка зимой как раз хватает, особенно в феврале - да еще и снег отражает.

Answer 3

Why does photosynthesis not occur in most plants in the winter in the temperate climate zone?

In the temperate climate zone, most plants do not undergo photosynthesis during the winter. This is primarily due to the following reasons:

1. Decreased sunlight: During the winter months, the days are shorter, and the angle of the sun is lower in the sky. This results in reduced sunlight reaching the plants, which is essential for photosynthesis to occur.

2. Low temperatures: Winter temperatures in the temperate climate zone are generally colder, and many plants are not adapted to photosynthesize efficiently in these conditions. Cold temperatures can slow down or inhibit the enzymatic reactions necessary for photosynthesis.

3. Limited water availability: In some regions, winter is associated with reduced precipitation and frozen soil, leading to limited water availability for plants. Water is a crucial component for photosynthesis, and its scarcity during the winter can further hinder the process.

4. Deciduous nature of plants: Many plants in the temperate climate zone are deciduous, meaning they shed their leaves during the winter. Deciduous plants enter a period of dormancy to conserve energy and protect themselves from the harsh winter conditions. Without leaves, photosynthesis cannot occur.

It is important to note that while most plants in the temperate climate zone do not photosynthesize during the winter, there are exceptions. Some evergreen plants, such as conifers, have adaptations that allow them to continue photosynthesis even in cold temperatures. These plants have needle-like leaves that minimize water loss and can photosynthesize at lower light intensities.

Overall, the combination of reduced sunlight, low temperatures, limited water availability, and the deciduous nature of many plants in the temperate climate zone contributes to the suspension of photosynthesis during the winter months.
