100
the basic unit of life
What is a cell?
100
Three facts of the cell theory
What is 1. All living things are composed of cells 2. Cells are the basic units of structure and function in living things 3. New cells are produced from existing cells
100
known as "little organs"
What is a organelle?
100
small organelles filled with enzymes.
What is a lysosome?
100
when particles move from an area where they are more concentrated to an area of less concentration.
What is diffusion?
200
A fundamental concept of biology
What is cell theory?
200
Characteristics of prokaryotes and eukaryotes. Give examples
What is Prokaryote cells have genetic material that is not contained in a nucleus. Eukaryote cells contain a nucleus in which their genetic material is separated from the rest of the cell. Examples include: Eukaryotes = plants, animals, fungi, & protists Prokaryotes = bacteria
200
A strong supposting layer around the membrane
What is a cell wall?
200
a place that stores materials such as water, salts, proteins and carbohydrates.
What is a vacuole?
200
when the concentration of the solute is the same throughout a system.
What is equilibrium?
300
Cells that contain nuclei and cells that do not contain nuclei
What are Eukaryotes (nuclei)? What are Prokaryotes (no nuclei)?
300
Differences and similarities between plant and animal cells
Plant cells have a vacuole and animal cells do not. The both have a nucleus and nucleolus. Animal cells have centrioles and plant cells do not.
300
small particles of RNA and protein found throughout the cytoplasm.
What is a ribosome?
300
organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use.
What is the mitochondria?
300
the diffusion of water through a selectively permeable membrane.
What is osmosis?
400
The portion of the cell outside the nucleus
What is Cytoplasm?
400
a cell goes through a specific process, just like a factory
How can you compare a cell to a factory?
400
The site where lipid components of the cell membrane are assembled.
What is a endoplasmic reticulum (ER)?
400
organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis.
What are chloroplasts?
400
meaning "same strength" meaning "below strength" meaning "above strength"
What is isotonic, hypotonic, and hypertonic?
500
Regulates what enters and leaves the cell and also provides protection and support
What is a cell membrane?
500
Proteins produced in the rough ER move next into an organelle.
What is the golgi apparatus?
500
compisition of nearly all cell membranes and a double layered sheet.
What is the lipid bilayer?
500
molecules that cant diffuse across the cell membranes lipid bilayer on their own, move through proteins instead.
What is facilitated diffusion?
