HumansThere are organisms that grow in size but do not change in their form or structure. For instance, humans are born with a specific number of fingers, hands and legs. This form remains the same as a human develops. The size of the parts can grown but the form stays the same.
PlantsThere exists other types of organisms that change in form as they grow. Plants first form a seedling which grown roots then leaves. A stem develops then later flowers, which fall, then after that comes the fruits which are also separated from the plant. The number of leaves in a plant keeps increasing as it grows. Unlike in humans, where the number of fingers stays the same but just can increase in size.
BusinessesThese two different modes of growth in unitary (like humans) and modular (like plants) organisms can inspire us to think about how a business can also grow. A business may grow by keeping its form yet growing the size of each of its existing parts. A store, for instance, may expand by renting more space and becoming physically bigger. Businesses may also expand by adding more 'modules' to themselves. A retail business may expand by adding new branches in the same way a tree expands by adding more branches and leaves. A company may grown by diversifying its offerings and adding more products that it produces or sells.
It is quite interesting to see how the world of plants and animals can inspire ways of looking at businesses.
