Answer:

Photosynthèsis is the process where green plants, algae, and some bacteria turn sunlight into chemical energy stored as glucose. This happens in the chloroplasts of plant cells, where chlorophyll captures sunlight.

The sunlight energy is used to change carbon dioxide from the air and water from the soil into glucose and oxygen. The glucose gives the plant energy and materials to grow, while the oxygen is released into the air.

Photosynthèsis is very important for the ecosystem because it starts the food chain by providing energy for almost all living things. It also helps keep the levels of oxygen and carbon dioxide in the air balanced, which is essential for life on Earth.

PHOTOSYNTHÈSIS

- Photosynthèsis is a key biological process where green plants, algae, and some bacteria turn sunlight into chemical energy stored in glucose. This process mainly happens in the chloroplasts of plant cells, which contain the pigment chlorophyll. Chlorophyll captures sunlight and uses its energy to start a series of chemical reactions.

During photosynthèsis, plants take in carbon dioxide (CO2) from the air through tiny openings called stomata and absorb water (H2O) from the soil through their roots. Using energy from sunlight, these materials undergo a series of reactions in the chloroplasts. The light energy splits water molecules into oxygen, protons, and electrons. Oxygen (O2) is released into the air, which is important for the breathing of almost all living organisms. The protons and electrons, along with carbon dioxide, are used to make glucose (C6H12O6) through the Calvin cycle. The simple chemical equation for photosynthèsis is:

[tex]\[ 6CO_2 + 6H_2O + light \, energy \rightarrow C_6H_{12}O_6 + 6O_2 \][/tex]

Photosynthèsis is very important for the ecosystem for several reasons:

  1. Foundation of the Food Chain: Photosynthèsis provides energy for almost all living things. Plants make food from simple substances like carbon dioxide and water. This food is then used by animals that eat plants, and these animals are eaten by other animals. This cycle keeps the food chain going.
  2. Oxygen Production: The oxygen released during photosynthèsis is crucial for animals that need air to breathe. Humans and many other organisms use this oxygen to create energy in their cells.
  3. Carbon Dioxide Regulation: Photosynthèsis helps regulate atmospheric levels of carbon dioxide, a major greenhouse gas. By converting CO2 into organic compounds, plants play a crucial role in mitigating climate change and maintaining the Earth's carbon balance.
  4. Biomass Production: Photosynthèsis leads to the growth and accumulation of plant biomass, which is not only a direct food source but also provides materials for shelter, medicine, and other human needs. It also contributes to soil health through the decay of organic matter, which enriches the soil with nutrients.
  5. Energy Storage: The glucose produced during photosynthèsis is stored as starch in plants and used as a long-term energy reserve. This stored energy can be harvested in the form of food, biofuels, and other resources.
