Фотосинтез зависит от интенсивности света, количества углекисилого газа и достаточного количества воды, 

Answer 2

Intensity of Photosynthesis

The intensity of photosynthesis depends on several factors. One of the key factors is the availability of light. Photosynthesis is a process by which plants convert light energy into chemical energy in the form of glucose. Light is absorbed by chlorophyll, a pigment found in the chloroplasts of plant cells, and this energy is used to power the photosynthetic reactions.

Another important factor that affects the intensity of photosynthesis is the concentration of carbon dioxide (CO2) in the atmosphere. Plants require CO2 as a raw material for photosynthesis. Higher concentrations of CO2 can increase the rate of photosynthesis, while lower concentrations can limit it.

Temperature also plays a crucial role in photosynthesis. Photosynthesis is an enzyme-driven process, and enzymes have specific temperature ranges at which they function optimally. Different plant species have different temperature optima for photosynthesis, but generally, photosynthesis rates increase with higher temperatures up to a certain point. Beyond that point, the enzymes involved in photosynthesis can be damaged, leading to a decrease in photosynthetic activity.

Water availability is another factor that affects the intensity of photosynthesis. Water is essential for the transport of nutrients and the maintenance of turgor pressure in plant cells. Inadequate water supply can lead to wilting and reduced photosynthetic activity.

Respiration

Respiration is the process by which organisms convert glucose and oxygen into energy, carbon dioxide, and water. It is a fundamental process that occurs in all living cells, including plant cells. Respiration provides the energy needed for various cellular activities, such as growth, reproduction, and maintenance of cellular structures.

In plants, respiration occurs in two main forms: aerobic respiration and anaerobic respiration. Aerobic respiration occurs in the presence of oxygen and is the most common form of respiration in plants. It involves the complete breakdown of glucose to produce energy, carbon dioxide, and water. This process takes place in the mitochondria of plant cells.

Anaerobic respiration, on the other hand, occurs in the absence of oxygen. Plants can resort to anaerobic respiration when oxygen is limited, such as in waterlogged soils. Anaerobic respiration produces less energy compared to aerobic respiration and can result in the accumulation of toxic byproducts, such as ethanol or lactic acid.

It's important to note that while photosynthesis and respiration are interconnected processes, they have opposite effects on atmospheric gases. Photosynthesis removes carbon dioxide from the atmosphere and releases oxygen, while respiration consumes oxygen and releases carbon dioxide.

Overall, the intensity of photosynthesis depends on factors such as light availability, carbon dioxide concentration, temperature, and water availability. Respiration, on the other hand, is a vital process that occurs in all living cells, including plant cells, and provides the energy needed for various cellular activities.
