Photosynthesis is the process by which green plants, algae and some bacteria convert light energy into energy in the form of glucose. This process takes place mainly in the chloroplasts of plant cells, particularly in the chlorophyll-containing structures called thylakoids. At its core, it is like a green energy factory in plant cells. 


Fotosynthese in planten

Plants have special green pigments called chlorophyll, which are like tiny solar panels. These chlorophyll molecules capture sunlight, providing the energy needed for photosynthesis. In addition, plants absorb water from the soil through their roots and absorb carbon dioxide from the air through tiny pores in their leaves called stomata. With sunlight, water and carbon dioxide, plants initiate the complex chemical reactions of photosynthesis. These reactions take place in specialised structures in plant cells called chloroplasts.

Light-dependent reactions in photosynthesis

During light-dependent reactions, the energy of sunlight is used to split water molecules into oxygen and hydrogen ions. This process releases oxygen into the air as a by-product. Meanwhile, the energy from sunlight is also used to convert ADP (adenosine diphosphate) and inorganic phosphates (P) into ATP (adenosine triphosphate), a molecule that stores energy. At the same time, NADP+ is converted into NADPH, another energy-carrying molecule.

Reactions in photosynthesis that are not light-dependent

In the light-independent reactions, also known as the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose, a simple sugar. This process takes place in the stroma of the chloroplasts. The glucose produced during photosynthesis serves as an essential energy source for plant growth, development and reproduction. It also provides the raw materials for building other organic molecules needed for plant functioning.

Overall, photosynthesis is a vital process that not only sustains plant life, but also enriches the atmosphere with oxygen, allowing all living organisms on earth to survive. It is nature's ingenious way of converting sunlight into the building blocks of life.

The role of fertilisers in the process of photosynthesis.

Macronutrients NPK

Nitrogen is essential for the synthesis of chlorophyll, the green pigment in plants responsible for capturing sunlight during photosynthesis. Sufficient nitrogen ensures healthy leaf growth and vibrant green colour, and optimises the plant's ability to absorb sunlight efficiently.

Phosphorus is involved in the conversion of light energy into chemical energy during photosynthesis. It promotes root development, which improves the plant's ability to absorb water and nutrients, ultimately supporting robust photosynthetic activity.

Potassium regulates the opening and closing of stomata, small pores on plant leaves that are crucial for gas exchange during photosynthesis. By maintaining stomatal function, potassium helps regulate water uptake and prevent water loss so that photosynthesis can take place under optimal conditions.

Calcium (Ca), Magnesium (Mg) and Iron (Fe)

Calcium (Ca): Although calcium is not directly involved in photosynthesis, it plays a crucial role in maintaining cell structure and function. It helps regulate cell permeability and facilitates the movement of other nutrients within the plant. In addition, calcium is essential for the activation of certain enzymes involved in metabolic pathways that support photosynthesis. Sufficient calcium contributes to the overall health of the plant and ensures efficient photosynthesis by supporting the structural integrity of cells and tissues.

Magnesium (Mg is a central component of the chlorophyll molecule, the pigment responsible for capturing light energy during photosynthesis. Without magnesium, chlorophyll synthesis is impaired, leading to reduced photosynthetic efficiency and poor plant growth. Magnesium also plays a role in activating enzymes involved in carbohydrate metabolism, further supporting the production of energy required for photosynthesis. Therefore, magnesium is crucial for optimising the photosynthesis process by ensuring the synthesis of functional chlorophyll molecules.

Iron (Fe) is a micronutrient essential for chlorophyll synthesis. It serves as a cofactor for enzymes involved in chlorophyll production and contributes to the green pigmentation of leaves and the efficient absorption of light energy. Iron deficiency can lead to chlorosis, a condition characterised by yellow leaves due to insufficient chlorophyll formation. By ensuring sufficient iron, fertilisers support robust chlorophyll synthesis, improving the plant's ability to capture sunlight and perform photosynthesis effectively.
