M4S2 - Unifying Themes of Life Flashcards
Life started in an ____?
Atom
What is the basic unit of life?
Cell/Cells
Bios means ____?, Logos means _____?
Life & Study
These are highly organized structures that made up of one or more cells, which are the basic units of life
Living Organisms
The source of energy for use and storage at the cellular level
ATP / Adenosine Triphosphate
Process by which energy is released by the breakdown of food substances
Cellular Respiration
All chemical processes, reactions, and energy changes happening inside the body
Metabolism
The process by which organism acquire food
Nutrition
What are the 2 Energy Acquisition?
Autotrophs and Heterotrophs
Organisms like plants capture energy from sunlight
Autotrophs
Organisms like animals obtain energy by consuming other organisms
Heterotrophs
Involves the absorption of essential nutrients from the environment or food
Nutrient Uptake
Nutrients are broken down and converted into usable forms of energy
Processing
Biological process that involves the removal of harmful metabolic byproducts
Waste Elimination
What are the 2 Importance of Waste Elimination?
Homeostasis & Toxicity Prevention
Adapting and Evolving
refers to an organisms ability to move or manipulate its environment
Motility
Adapting and Evolving
the ability of an organism to respond to stimuli from its environment
ex.
Animals: withdraw from painful stimuli
Plants: Grow towards light (phototropism)
Irritability
2 Types of Motility
Cellular level & Organismal level
Types of Motility
Movement of substances within cells (Cytoplasmic streaming)
Cellular Level
Types of Motility
Movement of the entire organism (walking, swimming, flying)
Organismal Level
Adapting and Evolving
process through which organisms adjust to their environment to improve survival reproduction
Adaptation
3 Types of Adaptation
Structural, Behavioral, Physiological
Types of Adaptation
Physical features ( bear, thick fur for cold climates)
Structural
Types of Adaptation
Actions or Behaviors
Behavioral
Types of Adaptation
Internal processes such as sweating
Physiological
Adapting and Evolving
change in the genetic makeup of a population over time, leading to the development of new species
Evolution
Reproducing and Continuing of Life
refers to the increase in size and number of cells in an organism
Growth
Reproducing and Continuing of Life
involves the process by which an organism matures from a single cell to a complex organism
Development
2 Stages of Growth and Develepment
Cell Division & Differentiation
Stages of Growth and Development
Growth through mitosis
Cell Division
Stages of Growth and Development
Cells specialize into different types (muscle cells, nerve cells)
Differentiation
Reproducing and Continuing of Life
process by which organisms produce offspring to continue their species
Reproduction
2 Types of Reproduction
Asexual Reproduction & Sexual Reproduction
Types of Reproduction
Offspring arise from a single parent
Asexual Reproduction
Types of Reproduction
Involves the fusion of gametes from two parents
Sexual Reproduction
Reproducing and Continuing of Life
the passing of traits from parents to offspring through genetic material (DNA)
Heredity
