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.

Vascular Tissue Most seed plants live on land. Recall from Chapter 4 that land plants face many challenges, including standing upright and supplying all their cells with food â¦ and water.Like ferns, seed plants meet these two challenges with vascular tissue.The thick walls of the cells in the vascular tissue help support the plants. In addition, food, water, and nutrients are transported throughout the plants in vascular tissue.There are two types of vascular tissue. Phloem (floh um) is the vascular tissue through which food moves. When food is made in the leaves, it enters the phloem and travels to other parts of the plant.ascular Tissue Most seed plants live on land.
