Study Notes
Characteristics of Life
- All living things are composed of similar chemical elements, reflecting the scientific principle of unity among living organisms.
- Living things often function and behave in ways strange to humans, emphasizing their unique characteristics and behaviors.
- The characteristic that defines life is the ability to function and behave in unique ways.
Diversity of Living Things
- The diversity of living things is due to evolutionary forces.
- The reason behind the diversity of living things is the variation in the evolutionary forces that act upon them.
Cell Structure
- The smallest structural and functional unit of all living things is the cell.
- Unicellular organisms are microscopic and include Paramecium and Bacteria.
- Paramecium is distinguished from Bacteria by its characteristics.
Classification of Organisms
- The science of classifying organisms into categories is known as taxonomy.
- The sequence of classification categories from larger to smaller is: domain, kingdom, phylum, class, order, family, genus, and species.
- A two-part scientific name is called a binomial name.
- The most closely related category in the sequence of classification categories is species.
Multicellular Organisms
- Multicellular organisms have organs, organ systems, and tissues that are not found in unicellular organisms.
Nervous System
- The nervous system includes the brain, spinal cord, and nerves.
Ecosystem
- The biosphere ecosystem is a giant web of life that is spread around the globe, highlighting the interdependence of living things.
- The existence of living things depends on one another, emphasizing their interconnectedness.
Plants
- Plants are photosynthetic and make their own food, distinguishing them from other organisms.
- This characteristic of plants allows them to produce their own food through photosynthesis.
