Diversity in the Living World

Such variety of plants and animals is a part of biodiversity. Plants and animals can be grouped on the basis of similarities and differences among them. Plants have similarities and differences based on features associated with roots, stems, leaves, flowers, and so on. The method of arranging things into groups based on their common features is called grouping. Plants can be grouped into herbs, shrubs, and trees based on their heights, types of stem, and branching patterns. Plants can also be grouped as dicotyledons (dicots) and monocotyledons (monocots) based on the number of cotyledons in their seeds. Monocots generally exhibit parallel venation in their leaves and possess fibrous roots while dicots typically exhibit reticulate venation in their leaves and possess taproots. Animals have different types of movement that can be a basis for their grouping. Biodiversity of different regions varies because of distinct environmental conditions. The special features that enable plants and animals to survive in a particular region are called adaptations. — Examisthan.com
