Explanation
Solution
- Manganese plays a crucial role in the photosynthesis process by enabling the splitting of water molecules, following the initiation of CO2 and water conversion into carbohydrates through Photosystem II (PSII) and light absorption.
- Magnesium , on the other hand, is involved in the activation of enzymes for both respiration and photosynthesis, as well as contributing to DNA and RNA synthesis.
- Boron is an essential nutrient for pollen germination and growth of pollen tubes.
- Finally, iron serves as an activator for catalase, an enzyme that contains four iron heme groups that allow it to effectively react with hydrogen peroxide.
