Leaves, stems, roots, and flowers are all made up of various tissues. Plant Tissues Plant Tissues fall into two large categories: Meristematic, or Permanent (Non-Meristematic) Meristematic Tissues Meristems are places in plants where cell division is occurring. During cell division, one cell becomes two cells.Each new cell can also divide.lant Tissues Plant Tissues fall into two large categories: Meristematic, or Permanent (Non-Meristematic) Meristematic Tissues Meristems are places in plants where cell division is occurring.

The vascular tissue in seedless vascular plants, like ferns, is made up of long,tube like cells. These cells carry water, minerals, and food to the cells throughout the plant.Non vascular plants like the moss are usually only a few cells thick.Vascular plants, on the other hand, can grow larger and thicker because the vascular tissue distributes water and nutrients to all plant cells. Vascular tissue is used to transport nutrients from the base of the plant to throughout the organism.     That's the gist of it.     Here's how it works:  â¦    First off, plants don't move like animals.
