This question is incomplete as it should have provided a choice of different tissue systems. I think the answer is a thin continuous cylinder made up of meristematic cells located between the wood (secondary xylem) and bark (secondary phloem) of roots and stems. The meristematic cells divide and add to the wood and inner bark.

Answer:
<u>Succession occurs after sudden catastrophic change. </u>
<u />
Explanation:
In communities, organisms occupy specific niches. These gradually evolve over time as these organisms interact with their geosphere. In ecological succession, a community may undergo several dynamic changes. These include primary succession and secondary succession- these communities eventually try to achieve equilibrium over time.
After catastrophic events, the microorganisms, primary succession occurs. Here, a colonizing species exploits a non-habitable region. These eventually make the region more habitable through nutrient cycling, weathering, etc. which ushers in secondary succession. Here, the communities become more complex with time, becoming more varied and an increasingly large food web.
