Question

Суть фотосинтеза и его роль краткий конспект​

Answer 1

Фотосинтез — это процесс, благодаря которому существует большинство живых организмов на нашей планете.

Фотосинтез

процесс образования органических веществ из углекислого газа (CO2) и воды (H2O), протекающий с использованием солнечной энергии.Фотосинтез происходит в хлоропластах у растений или на мезосомах у прокариот. На цитоплазматической мембране у этих организмов содержатся молекулы зелёного пигмента — хлорофилла.

The Essence of Photosynthesis and Its Role: A Brief Summary

Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen. This process is crucial for the survival of plants and other organisms that depend on them for food and oxygen.

Photosynthesis can be summarized in the following steps:

1. Absorption of Light: Chlorophyll, a pigment found in the chloroplasts of plant cells, absorbs light energy from the sun.

2. Conversion of Light Energy: The absorbed light energy is converted into chemical energy in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are energy carriers.

3. Splitting of Water: Water molecules are split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form oxygen gas (O2), which is released into the atmosphere as a byproduct.

4. Synthesis of Glucose: Carbon dioxide (CO2) from the atmosphere enters the plant through tiny openings called stomata. The hydrogen ions (H+) and energy carriers (ATP and NADPH) are used to convert the carbon dioxide into glucose (C6H12O6).

5. Storage and Utilization of Glucose: Glucose is stored in various parts of the plant, such as fruits, roots, and seeds. It serves as a source of energy for the plant's growth, reproduction, and other metabolic processes.

The role of photosynthesis:

1. Production of Oxygen: Photosynthesis is responsible for producing a significant amount of the oxygen present in the Earth's atmosphere. This oxygen is essential for the survival of aerobic organisms, including humans.

2. Conversion of Solar Energy: Photosynthesis converts solar energy into chemical energy stored in glucose. This energy is used by plants and other organisms that consume plants as a source of food.

3. Carbon Dioxide Reduction: Photosynthesis helps reduce the concentration of carbon dioxide in the atmosphere. Carbon dioxide is a greenhouse gas that contributes to global warming. By absorbing carbon dioxide during photosynthesis, plants play a crucial role in mitigating climate change.

4. Food Production: Photosynthesis is the primary source of food for most organisms on Earth. Plants produce glucose through photosynthesis, which serves as a source of energy for herbivores, omnivores, and carnivores.

5. Ecosystem Stability: Photosynthesis is vital for maintaining the balance of ecosystems. It provides energy for the entire food chain and supports the growth of plants, which provide habitats for various organisms.
