Cell types that can be multicellular or unicellular.
What are eukaryotic cells?
Structures enclosed by a membrane, for ex., nucleus, chloroplasts, mitochondria, Golgi body, and ER.
What are membrane bound organelles?
Type of environment that Archaea can be found, for example: very cold, hot, salty, or acidic.
What are extreme environments?
Structure that provides support, rigidity and protection to plant cells.
What is cell wall?
Fluid/liquid part of the cell that contains/supports organelles and other structures.

What is homeostasis?
Structure in the prokaryotic cell that is not a nucleus but contains genetic material.
What is nucleoid region?
Structure that converts light energy into glucose (food) for plants/algae/protists during photosynthesis.
What are chloroplasts?
Structure inside the nucleus of eukaryotic cells that makes ribosomes.
What is nucleolus?
The relationship between cells and living things over time.
What is the cell theory?

Who is Rudolph Virchow?
Specialized cell structures that perform a specific job/function.
What are organelles?
Cells that differentiate (change) to play a specific role to do a job for the cell.
What are specialized cells?
Structures used in bacterial cells for attachment, movement, and communication.

What are cell membrane, ribosomes, cytoplasm, and genetic material?
Method or pathway cells use to communicate with each other to coordinate activities and respond to external signaling.
What are signaling pathways?
Important roles of prokaryotic cells such as nutrient cycling, decompositon, and symbiotic relationships.
What are ecological processes?
Organelle that extends from the nucleus, has ribosomes, & involved in protein sythesis, lipid metabolism, and detoxification.
What is ER, or endoplasmic reticulum?
Organelle that modifies, sorts, and packages proteins and lipids for transport throughout the cell.
What is Golgi body (apparatus)?
