Give two examples of complex tissues that constitute vascular bundles in plants.

The two complex tissues forming vascular bundles are xylem and phloem. These tissues work together as an integrated transport system within plants. Xylem transports water and minerals upward from roots, while phloem distributes organic nutrients throughout the plant. In vascular bundles, these tissues are typically arranged together, often with cambium tissue between them in dicots, creating an efficient two-way transport network. This vascular system is analogous to the circulatory system in animals, ensuring distribution of essential materials to all plant parts.
