The development of tracheid helped land plants to take in more co 2: grow to very large sizes.
How did plants become higher thanks to the evolution of their roots?
Plant Vascular Evolution
True roots consisting of vascular tissues have emerged in vascular plants. Rhizoids can absorb less water and minerals from the soil than roots can. Additionally, they firmly attach plants in the ground so that they can enlarge without falling over.
What function do stomata provide in a plant like Cooksonia?
Due to their concentration at the terminals of the axes, some Cooksonia species developed stomata, which were involved in gas exchange. This was likely done to aid in the transpiration-driven transfer of dissolved minerals in the xylem.
