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 tissues provide support and rigidity to the plant, other than the circulation of food and water. There are lignified tissues associate with xylem. Organs of the plant are developed well with different combination of tissues. There are four types of tissues found in vascular plants.They are vascular tissues, meristamatic tissues, ground tissues, and dermal tissues. The principal generation phase of vascular plant is sporophyte, which has two sets of chromosomes (diploid). Also, these plants comprise of true roots, stem, leaves.Vascular plants include ferns, conifers, and flowering plants.he principal generation phase of vascular plant is sporophyte, which has two sets of chromosomes (diploid).
