The Cell Flashcards
A way of dividing and organizing topics for studying.
Hierarchy
Properties observed that aren’t present in the preceding level of the hierarchy and are caused by increasing complexity.
Emergent Properties
The study of organisms and how they interact with their environment and other organisms.
The study of interactions of each part of the environment with the others as well as how a change in one part affects another.
The study of organisms and the impact that they have on the environment or that the environment has on them.
Systems Biology
Hierarchical levels of organization (smallest to largest):
Atom, Molecule, Cell Organelles, Cell, Tissue, Organ, Organ System, Organism, Population, Biocenosis (Community), Ecosystem, Biome, Biosphere (Earth)
Characteristics of living things:
How is life defined?
Cellular Composition
Reproduction
Response and Adaptation (Homeostasis)
Metabolism
Evolution
A characteristic of living things…
Cells are the fundamental units of any organism.
Cells do everything the organism needs to do to survive (generate/store energy, remove waste, create proteins).
Most cells also contain instructions to build that cell (in the form of DNA).
Cellular Composition
A characteristic of living things…
Organisms must reproduce to pass down information that their DNA carries and ensure the future of that species.
Either by asexual or sexual reproduction.
Reproduction
A characteristic of living things…
Organisms must be able to respond to their environments to survive.
Need to adapt to the environment to maintain organism’s homeostasis.
Response and Adaptation
Requires only 1 parent for reproduction.
ex. bacteria
Asexual Reproduction
Requires 2 parents for reproduction.
ex. humans
Sexual Reproduction
The stability of an organism’s internal conditions.
Homeostasis
A characteristic of living things…
A key part of maintaining homeostasis is maintaining the chemical reactions that the organism undergoes daily.
Some rely on internal processes to create their own food (plants & photosynthesis) while others need to consume food from external sources.
Energy from mood (made or consumed) is used to drive the chemical reactions required to maintain life.
Metabolism
A characteristic of living things…
Living things evolve to become better suited to their changing environments… Due to mutations (changes) in DNA.
Evolution
A method of dividing and organizing living things based on emergent properties.
