Plants need a lot of nutrients to grow.
To grow, plants (except carnivores) need minerals (present in water), sunlight, and carbon dioxide. With these elements, plants perform the photosynthesis process to generate energy and to perform their physical development. Nutrients are present in the soil and are absorbed by the plants through the roots.
Nutrient absorption in plants
Vascular vegetables obtain the fundamental nutrients for their development through the absorption process. This process occurs through the hair on the roots. Therefore, water and mineral salts are absorbed in these hairs, whose epidermal cells are permeable.
Key Plant Nutrients
Macronutrients are those needed in large quantities.
- Potassium: regulates the osmotic pressure in plant cells.
- Nitrogen: acts in the process of synthesis of nucleic acids and proteins.
- Calcium: acts on the process of plant metabolism.
- Phosphorus: enters the formation of nucleic acid and ATP molecules.
- Magnesium: important component of chlorophyll.
- Sulfur: acts in the production of chloroplasts.
There are also micronutrients, which are those needed in small quantities for vegetables.
- Manganese: operates in the production of chloroplasts.
- Boron: acts on the division of plant cells and the transport of sugars.
- Zinc: acts on the transcription of plant DNA.
- Iron: important in the photosynthesis process.
- Copper: acts on photosynthesis and enzymatic processes.
- Molybdenum: acts mainly in the production of amino acids.
- Chlorine: It is important mainly in the osmotic process.
