GCSE Biology - Characteristics of Living Things (Organisms) #3

The video tutorial explores the characteristics of living organisms, using the acronym Mrs. Gren to outline seven key features: movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. It emphasizes that while non-living things may exhibit some of these features, only living organisms possess all seven. The tutorial explains each feature in detail, highlighting how they manifest in different organisms. It concludes by noting that all living organisms are cellular, and viruses do not qualify as living because they lack these features.
