This lecture explains the characteristics and life processes of living organisms in simple terms. It teaches how to identify living and non-living things, explaining that living things—like plants, animals, and microbes—need food, grow, move, reproduce, and respond to their surroundings, while non-living things do not. The seven main characteristics of living organisms are growth, movement, respiration, nutrition, excretion, reproduction, and sensitivity.

The lesson also covers life processes such as nutrition (plants make food through photosynthesis, animals eat plants or other animals), respiration (breathing to release energy), excretion (removing waste), movement, growth, reproduction, and response to environment. It compares plants and animals, showing differences in nutrition, movement, respiration, excretion, growth, reproduction, and sensitivity. Important terms discussed include organisms, photosynthesis, respiration, excretion, sensitivity, vertebrates, invertebrates, and biodiversity. The lecture uses examples, demonstrations, and activities to make learning interactive and easy to understand.
