Because the group of small cells would have a greater surface area-to-volume ratio, so they are able to exchange materials with their surroundings more efficiently.

Answer
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Explanation:
Auxins exert various effects including elongation growth. The basic effect of auxin involves regulation of stem growth. This occurs by stimulation of cell growth in the direction of elongation.Auxin inhibits the growth of axillary buds.
