Points to Study Criteria for classification.Classification of plant.Flowering and non-flowering plants. Plants can be classified according to the differences in the

height of their steams and their branches. 1) Trees 2) Shrubs 3) Climbers and Creepers 4) Herbs

Classification of plants based of their life-cycle . 1) Perennials 2) Biennials 3)Annuals

Classification of animals 1) Wild and domestic animals. 2) Unicellular and

Multicellular animals . 3) Terrestrial , Aquatic , Amphibious animals 4) Vertebrate and Invertebrate animals. 5) Classification based on body covering

Criteria for classification

1.There are various varieties of plants and animals in our surroundings.

2.The credit of classification of plants goes to Carolus Linnaeus.

3.The similarities ,differences and variety are the criteria of classification.

3. Classification based on live-cycle.Perennials

– Plants that live

many year. e.g.-

Mango, Coconut, Neem .

Biennials – Plants that live for 2 years. e.g.- Carrot, Beat, Radish.

Annuals – Plants that live for 1 year. e.g.-

Bajara , Jowar , Sunflower.
