The earliest vascular plants on land had underground stems (rhizomes), but no roots. Water and mineral nutrients were most likely obtained by absorption by mycorrhizae.
How are Water and mineral nutrients were most likely obtained?
- Through the development of a network of filaments that investigates the soil and gives the plant access to additional nutrients and water, mycorrhizae play a significant role in actively boosting water intake.
- Water is absorbed from the soil via mycorrhizal hyphae. In trifoliate oranges, the hyphal water absorption rate ranged from 0.126 to 1.973 mg H2O/h/mm.
- Mycorrhizal fungi can develop mycelial networks in a variety of inert growth mediums, including soil, coco coir, rock wool, and others. As long as the habitat is suitably aerated, they can even survive in a completely water-based setting, but they cannot reproduce there.
- By using photosynthesis, the plant creates organic molecules like sugars and gives them to the fungus. The fungus then gives the plant water and mineral nutrients from the soil, such as phosphorus.
