Does the growth pattern in plants differ from that in animals? Do all the parts of plant grow indefinitely? If not, name the regions of the plant, which can grow indefinitely.
Ans.
Animals and plants have different growth patterns and habits. Animals experience growth of definite, determinate form, which means they experience limited growth or stop growth after attaining maturity. Plants, on the other hand, can experience growth of definite or indefinite and indeterminate form. They can stop growing after attaining maturity of developing leaves and flowers or parts like the stem, and their branches can keep continuing to grow. Plants experience continuous growth since they contain meristematic areas with potential for cell-division, whereas animals have cell division only to replace and repair and not for the purpose of growth.
