- Importance of minerals: macro and micro-nutrients; three deficiency diseases caused by lack of these essential nutrients.
- Reproduction in Plant and Animals:
- Types of Asexual reproduction:
Binary fission, budding, fragmentation, spore formation, vegetative propagation, artificial propagation by tissue culture (basic process along with a suitable example of each)

- Biotic components consisting of producers, consumers, decomposers. Meaning of food chain. Food web, and pyramid of numbers
- Interdependence between organisms: symbiosis, parasitism and predation
- Brief account of abiotic or non-living components such as air, soil, water and climatic factors such as sunlight, temperature, humidity and wind;
- Only, forest ecosystem with its flora and fauna to be taught.
- Human Body:Endocrine, Circulatory and Nervous System :
- Endocrine System
- Two types of glands- exocrine, endocrine (basic concept and difference);
- Hormone (definition).
- Hormonal glands – (thyroid, adrenal, pancreas, pituitary); location and function of each.
- Following points to be studied in tabular form: name of gland, location in body, secretion, function.

- Circulation of blood as double circulation.
- Blood Groups (A, B, AB and O): universal donor and universal acceptor.
- Conditions related to the functioning of the heart: palpitations, cardiac arrest and hypertension.
- Introduction of lymphatic system as a parallel circulatory system.
- Nervous System
- Types of nerves: sensory, motor, mixed (function only). Cranial and spinal nerves (only definition and number).
