Meristem, region of cells capable of division and growth in plants.Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses). For example, the intercalary tissue at the base of a blade of grass allows it to regrow after being cut. starch grains within meristem cells are denser than the cytoplasm and move in response to gravity. auxin flows "downhill" within the plant due to force of gravity acting on each auxin molecule. Being meristematic, the secondary meristem is comprised of undifferentiated (or partially differentiated), actively dividing cells. The meristems that originate from permanent cells by dedifferentiation are called the secondary meristems. Intercalary meristems. Cork cambium, also called phellogen, is another meristematic tissue developed in the cortex region. Physics. The bark protects the plant against physical damage and helps reduce water loss.
