Step1 Step2 Step3 Step4 Access the application Photosynthesis with the help of the provided URL or QR code. Install in your device. After opening the app, Click LEVELS to begin the game. A palnt sapling will be in one side, and sun rays will be at the other side. You have to drag and adjust the mirror so that the sunlight rays will fall on the plant. At the top left, there is a indicator to show the timings. Explore and complete the other levels gradually. Introduction The variety in nature and habits of animals in the biosphere are quite amazing and interesting. What we see around us may be just few, but there are innumerable species living in this world. You have learnt in lower classes about the classification of animal kingdom. We will recall here that ‘Kingdom Animalia’ is divided into two groups, Invertebrates and Chordates . There occurs a great diversity in the habit, habitat, structural organisation and mode of reproduction between the animals existing on earth. In this chapter, you will understand the structural morphology and anatomy of an Invertebrate (Leech) and a Vertebrate (Rabbit). The scientific name of the Indian cattle leech is Hirudinaria granulosa which belongs to Phylum Annelida . Annelids are metamerically segmented worms with well developed organ systems. The scientific name of the common rabbit is Oryctolagus cuniculus . It is represents Phylum Chordata and Class Mammalia . Mammals occupy the highest group in the animal kingdom and show advancement over the other groups of animals. They are warm blooded and possess covering of hair on the body. Mammary gland in females is the most striking feature of a mammal. Let us now study about the morphology of leech and rabbit in detail.
