Venning (1949)and Walker(1957)studied the effects of wind on celery collenchyma and found that while the number of collenchyma bundles remained unchanged.Larger areas of collenchyma with heavier cell wall thickening developed at an early stage of experiment Walker (1960) measured the length of collenchyma cell in Datura Stranonium and found that mechanical stimulation decreased their size and thus inhabited elongation. Critically evaluate the experiment results of both.
