Study Notes

Reproduction

  • Living organisms must be able to reproduce either sexually or asexually.
  • Sexual reproduction involves two parent organisms contributing DNA to offspring.
  • Asexual reproduction involves a single parent, common in unicellular organisms.
  • Heredity allows organisms to pass on genetic information (DNA) to the next generation.

Cells

  • All living things are composed of cells, the fundamental unit of life.
  • Unicellular organisms consist of one cell, whereas multicellular organisms have multiple cells.

Energy

  • Living organisms must maintain and produce energy to sustain life.
  • Energy is obtained through consumption of food and liquids.

Response to the Environment

  • Organisms actively respond to various environmental stimuli such as sounds, smells, and temperature changes.

Homeostasis

  • Homeostasis refers to an organism's ability to maintain stable internal conditions despite external changes.
  • It encompasses processes such as cell growth, internal balance, and response to environmental factors.

Development and Growth

  • All living things undergo development and growth, which involves changes over time.
  • For example, plants grow from seeds into mature plants, illustrating the developmental process.

Change Over Time (Evolution)

  • Evolution entails changes within species over time rather than changes in individual organisms.
  • Every species has the potential to change over generations.

Chemicals of Life

  • Living organisms are primarily composed of six essential chemicals: phosphorus, carbon, oxygen, sulfur, nitrogen, and hydrogen.
  • There are 118 known elements, but the biochemical composition of life is largely governed by these six elements, which can exist in various arrangements.
  • Some organisms may include arsenic alongside the primary six chemicals.
