Flowering plants grow in a wide variety of habitats and environments. They can go from germination of a seed to a mature plant producing new seeds in as little as a month or as long as 150 years. Plants that complete their life cycle in a single season are called annuals; while biennials take two years; and perennials may take several to many years to go from germinated seed to producing new seeds. Fruits and Seeds The taste of a fruit depends on the combinations present in it. Normally a fruit contains the materials like cellulose, proteins, starch, vitamins, certain acids, fructose or sugar. All these materials are found in mixed form inside the fruit and they have different proportions in different fruits. Fruits of sweet taste have more fructose in them whereas the fruits of sour taste have more acids in them. Some fruits are sweet as well as sour in taste like orange, as it has almost equal quantities of fructose and acids in it.
Fruits like limes and lemons have a sour taste; they do not become a sweet taste even after ripening due to the presence of excessive amount of acids. Raw bananas have more starch but when the fruit gets ripen, the starch gets converted into fructose. The chemical changes take place inside the fruit during the process of ripening, due to these changes the amount of sugar increases in fruit and it becomes sweet. You will see that even two fruits of same type have different taste like two mangoes or two apples do not have same taste but they are different in taste. The reason behind it is that some fruit has many varieties and there is also variation in the quality of soil, manure, climate, water and technique of growing etc.
These variations change the proportion of the compounds inside the fruit that causes the difference of taste. Fruits like lemons have sour taste; they do not have a sweet taste even after ripening due to the presence of excessive amount of acids. There is a correlation between the tastes
