Study Notes
Characteristics of Living Organisms
- Matter with biological processes is distinguished from non-living matter by its ability to grow, respond to stimuli, reproduce, and maintain homeostasis.
Viruses and Life
- Defining viruses as living organisms is difficult because they lack cellular structure and cannot reproduce on their own, but they can replicate inside host cells.
Distribution of Life on Earth
- Life exists on Earth in various forms and habitats, from the simplest organisms to complex ecosystems.
Ancient Theories of Life
- The Hylomorphic Theory proposes that living things have souls and embody both form and matter.
Origin of Life
- The origin of life on Earth is believed to date back to at least 3.5 billion years ago, according to scientific evidence.
