Question

Процессы фотосинтеза нередко называют воздушным питанием, поскольку углекислый газ поступает в организм растения из воздуха. Приведите доказательства того, что процессы фотосинтеза связаны не только с воздушным, но и с почвенным питанием растений.

Answer 1

для фотосинтеза необходимы: со2, вода, солнечное тепловое излучение.

вода, полученная растением при всасывании еще из почвы корневыми волосками (корневое питание), расходуется в процессе фотосинтеза (при воздушном питании)

Answer 2

The Relationship Between Photosynthesis and Soil Nutrition

Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. While it is commonly known that carbon dioxide is obtained from the air during photosynthesis, there is also a significant relationship between photosynthesis and soil nutrition. Here are some pieces of evidence that support the connection between photosynthesis and soil nutrition:

1. Mineral Nutrients: Plants require various mineral nutrients for their growth and development. These nutrients, such as nitrogen, phosphorus, and potassium, are typically obtained from the soil. They play essential roles in the synthesis of chlorophyll, enzymes, and other molecules involved in photosynthesis.

2. Root Uptake: Plant roots absorb water and mineral nutrients from the soil through a process called root uptake. The water and nutrients taken up by the roots are transported to the leaves, where photosynthesis primarily occurs. This process ensures that plants have an adequate supply of nutrients to support photosynthesis.

3. Chlorophyll Synthesis: Chlorophyll, the pigment responsible for capturing light energy during photosynthesis, requires certain nutrients for its synthesis. For example, magnesium is an essential component of chlorophyll molecules. Without an adequate supply of magnesium from the soil, plants may exhibit chlorosis, a condition characterized by yellowing of leaves due to a lack of chlorophyll.

4. Energy Storage: Photosynthesis produces glucose, which serves as an energy source for plants. Excess glucose is converted into starch and stored in various plant parts, including roots. These stored energy reserves can be utilized during periods of low light or limited photosynthetic activity. The availability of nutrients in the soil directly affects the plant's ability to produce and store glucose through photosynthesis.

5. Plant Growth and Development: Adequate soil nutrition is crucial for overall plant growth and development. Nutrient deficiencies can impair photosynthetic efficiency, leading to stunted growth, reduced biomass production, and decreased crop yields. Conversely, providing plants with optimal soil nutrition can enhance photosynthetic performance and promote healthy growth.

In summary, while photosynthesis is often associated with obtaining carbon dioxide from the air, it is closely linked to soil nutrition as well. Plants rely on mineral nutrients obtained from the soil to support various aspects of photosynthesis, including chlorophyll synthesis, energy storage, and overall plant growth and development.
