Study Notes
Growth and Development of Organisms
- Organisms change in predictable ways from birth to old age, with characteristic structures, functions, and behaviors.
- Cell division via mitosis is essential for growth, development, and repair in multicellular organisms.
- Successive cell divisions produce many cells, with identical genetic material but small differences in gene expression due to environmental factors.
- Differentiation allows specialized cells to form and perform diverse functions from a single fertilized egg.
- Sexual reproduction involves meiosis, producing sex cells with only one member from each chromosome pair.
- Plants and animals have unique and diverse life cycles that include growth, development into adults, reproduction, and death.
- Reproduction is essential for the continued existence of every kind of organism.
- Animals engage in characteristic behaviors that increase the odds of reproduction.
- Plants reproduce in various ways, sometimes depending on animal behavior and specialized features.
- Genetic factors, food intake, and interactions with other organisms control animal growth, with each species having a typical adult size range.
- Multicellular organisms develop into complex organisms composed of systems of tissues and organs that work together to meet the needs of the whole organism.
- Cellular division and differentiation produce and maintain these complex organisms.
