Answer:
3. The apical meristem, found just below the surface of the branches and roots furthest from the center of the plant, is continually dividing. Some cells divide into more meristematic cells, while other cells divide and differentiate into structural or vascular cells. There are two apical meristem locations in most plants. The shoot apical meristem is found in the tips of plants. This apical meristem is responsible for creating cells and growth to drive the plant into the light and air, where it can photosynthesize and exchange built up gases.
The root apical meristem is found at the tips of roots. Sensing the conditions of the soil around the root, signals are created within the apical meristem which direct the plant towards water and desired nutrients. It is for this reason that roots often invade pipes for water and drainage, which carry many of the nutrients they need. The apical meristem, protected by the root cap continues to produce cells even as the root cap is scraped away as it pushes through the dirt. The apical meristem must produce enough cells to not only extend into the soil, but also to replace the cells lost to abrasion
Answer:
1. meristematic tissue and permanent tissue
2meristem
3.Apical meristem, region of cells capable of division and growth in the root and shoot tips in plants.it is located at meristem zones
4.Xylem and phloem are the two most important complex tissues
5.collenchyma gives flexibility in plants
