The three plants, parsley, mint and chive, shown in Figure 9.1 are examples of crops grown commercially to sell to markets and shops for food. The parsley plant was grown from seed, the mint from a separated shoot and the chive from a small bulb separated from a cluster of bulbs. Plants grown from seed (as the parsley was) are the result of sexual reproduction. Plants grown by other methods (as the mint and chive were) are the result of asexual (not sexual) reproduction. In the commercial crop production of flowering plants there are many different methods, but all must use either sexual reproduction or asexual reproduction.
