Living organisms exhibit essential characteristics that define life, with eight key features distinguishing living from non-living entities. These characteristics of life in biology encompass cellular organization, reproduction, genetic coding, growth, energy usage, stimulus response, homeostasis, and evolution.

Page 2: Genetic Code, Growth, and Response Mechanisms

This section delves deeper into the Universal genetic code in living organisms and various life processes including growth, development, and response mechanisms.

Definition: DNA (Deoxyribonucleic acid) determines individual characteristics and is composed of nucleotides.

Highlight: Response to stimuli in living organisms examples include reactions to touch, temperature, and internal signals like pain.

Vocabulary:

  • Autotroph: Organisms that produce their own energy
  • Heterotroph: Organisms that obtain energy through food consumption
  • Metabolism: Combined chemical reactions in life processes

Example: When the body is low on water, internal stimuli trigger thirst as a homeostatic response.

Page 3: Evolution and Viral Classification

The final section explores evolutionary processes and provides detailed information about viral characteristics and reproduction methods.

Definition: Evolution involves genetic changes over time as organisms adapt to their environment.

Highlight: Viruses are classified based on their genetic makeup (DNA/RNA), shape, and presence of membranous envelopes.

Vocabulary:

  • Lytic cycle: Viral reproduction resulting in host cell destruction
  • Lysogenic cycle: Viral genome incorporation without host cell death
  • Antibiotics: Compounds that block cellular processes in living organisms

Example: Viruses use deceptive protein structures similar to host cells to gain entry undetected.

Quote: "Anti-means not or opposite, biotic means living, antibiotics block the cellular processes of biotic organisms."

Page 1: Introduction to Biology and Basic Characteristics of Life

Biology represents the scientific study of life, encompassing various aspects of living organisms. The page introduces the 8 characteristics of life biology that define living things.

Definition: Biology derives from "logy," meaning "the study of something," and focuses on exploring and discovering life processes.

Highlight: All eight characteristics must be maintained for an organism to be considered living.

Example: Practical applications of biology include medicinal plants like sage for headaches and biotechnology developments such as pacemakers.

Vocabulary:

  • Cells: Basic units of life, classified as prokaryotic or eukaryotic
  • Species: Groups of organisms capable of producing fertile offspring

Quote: "Living things survive to reproduce and pass on favorable traits to viable offspring."
