Characteristics and Functions of Living Things

The video tutorial explains the characteristics of living things, differentiating them from non-living entities like rocks. It covers the cellular structure of organisms, the chemical composition of cells, and how living things react to stimuli. The video also discusses reproduction, energy acquisition through photosynthesis and consumption, and debunks the idea of spontaneous generation. Key terms such as organism, cell, and homeostasis are introduced, emphasizing the importance of stable internal conditions for life.

What is the primary difference between a rock and a living organism?
