Phloem

Phloem

Vascular plants are characterized by their tissue adaptations that facilitate the transportation of nutrients through the plant. The two types of vascular tissue are xylem and phloem. Phloem is the tissue that transports “food” and solid nutrients throughout the plant. Therefore, the tissue’s cells are arranged into tubes that mete out organic matter, such as sugars and amino acids, to the plant’s organs. This vascular adaptation makes these plant stems strong enough to support against gravity and thereby grow taller. Subsequently, the phloem can transport mineral nutrients high above the ground, a marked advantage against short plants to access necessary resources for photosynthesis, such as sunlight. Vascular plants, such as the one depicted in the image, shoots tall above the ground, thanks to the lignified phloem and xylem it possesses.
