I Diversity in Living World (25 Periods) Diversity of living organisms Classification of the living organisms (five kingdom classification, major groups and principles of classification within each kingdom). Systematics and binomial System of nomenclature Salient features of animal (non chordates up to phylum level and chordates up to class level) and plant (major groups; Angiosperms up to subclass) classification. Botanical gardens, herbaria, zoological parks and museums. II Structural Organisation in Animals and Plants (30 Periods) Tissues in animals and plants. Morphology, anatomy and functions of different parts of flowering plants: Root, stem, leaf, inflorescence, flower, fruit and seed. Morphology, anatomy and functions of different systems of an annelid (earthworm), an insect (cockroach) and an amphibian (frog). III CELL: STRUCTURE AND FUNCTION (40 Periods) Cell: cell wall, cell membrane and cell organelles’ (plastids, mitochondria, endoplasmic reticulum, Golgi bodies/dictyosomes, ribosomes, lysosomes, vacuoles, centrioles) and nuclear organization. Mitosis, meiosis, cell cycle. Basic chemical constituents of living bodies. Structure and functions of carbohydrates, proteins, lipids and nucleic acids. Enzymes: types, properties and function. IV Plant Physiology (40 Periods) Movement of water, food, nutrients and gases, Plants and Water Mineral nutrition, respiration, Photosynthesis, Plant growth and development. V Human Physiology (45 Periods) Digestion and absorption. Breathing and respiration. Body fluids and circulation. Excretory products and elimination. Locomotion and movement. Control and coordination.
