Lecture 1 Flashcards
Atoms/Molecules
Not Living/ Non-living
Cell
-smallest living unit
-a chemistry emerge
Tissue
Made of similar types of cells that work together for a common purpose.
Organ Systems
Made of different tissue types working together
Organism
A living thing based on 7 characteristics
Population
All individuals of a particular type (species) interacting in a particular place
Community
- all the different types (species) of organisms that may interact in a particular place.
-all living things interacting with each other.
Ecosystem
All different types of organism, plus the nonliving (abiotic) components necessary for existence.

Eukaryotic
A domain that is made up of organisms that contain a nucleus within their cells.
Bacteria
Microscopic living organisms that have only one cell.
Archaea
Single-celled microorganisms with structure similar to bacteria
What do both domain bacteria and domain archaea both have?
- Physically Similar: Prokaryotic Cell Structure (Simple, lack of nucleus and membrane bound)
-Microscopic Single Cell (Unicellular) Organism.
Eukaryotic Cell Structure
- DNA in a nucleus
-Many membrane bound organelles
