Answer

  The main purpose of classifying plants is to ensure that the right plants are correctly named grouped and are identified regardless of where it is on earth. Plants are classified into:

1. The evergreens are plants that retain leaves at all times (all year round).
2. Woody plants can also be grouped as deciduous or evergreen.
3. Deciduous plants are seasonal plants which shed its leaves at the end of the growing season, either during the winter season in the temperate climate or during the dry season in the tropical climate.

Apart from the above features, there are some plant species which can be classified based on their life cycle.

• Annuals

These are plants that complete their life cycle, seed – plant – seed during a single season. They are normally herbaceous. Few examples like Corn, rice, wheat, and pulses are annuals plant.

• Biennials

These are plants that require two years to complete their life cycle. They are normally herbaceous. For example Carrot, cabbage, onions, and beetroot are biennials plant.

• Perennials

These are plants that are long-lived, more than two years and are usually woody or herbaceous. Rose, lavender, and lilies are few examples of perennials.
