Cell Theory
This term means "composed of one cell."
What is unicellular?
This organelle controls the passage of materials into and out of the cell.
What is the cell (plasma) membrane?
This type of cell transport involves the movement of water down a concentration gradient.
What is osmosis?
If a cell has 16 chromosomes, its daughter cells will EACH have this many chromosomes.
What is 16?
This term means "composed of many cells."
This organelle protects the DNA.
What is the nucleus?
This type of transport uses a transport protein to move large molecules like glucose down a concentration gradient without using energy.
What is facilitated diffusion?
This term means programed cell death.
These types of organisms are multicellular and have cells that contain a nucleus.
What are eukaryotes?
These organelles are present in prokaryotes and eukaryotes and make proteins.
What are ribosomes?
What is diffusion or simple diffusion?
These cells are undifferentiated cells that can become differentiated into one or more types of specialized cells.
What are stem cells?
List 2 of the 3 principles of cell theory.
All living things are made of cells
Cells are the most basic unit of life
All cells come from other cells
These organelles digest foreign substances and worn out cell parts.
What are lysosomes?
This type of transport uses energy and vesicles to move particles into the cell, such as white blood cells engulfing bacteria.
What is endocytosis?
These are the two main purposes for cell division.
What are growth and repair?
Describe 2 differences between prokaryotic and eukaryotic cells.
Prokaryotic: no nucleus, no membrane-bound organelles, unicellular, divide by binary fission.
Eukaryotic: nucleus, membrane-bound organelles, uni- or multicellular, divide by mitosis.
This organelle modifies and packages proteins.
What is the Golgi apparatus?
The three types of solutions are hypertonic, hypotonic, and isotonic. Explain what would happen to cells placed in each type of solution.
Hypertonic: water leaves cell, cell shrivels
Hypotonic: water enters cell, cell swells and bursts
Isotonic: cell stays the same
If a cell does not go through S phase of the cell cycle before mitosis, what might be wrong with its daughter cells?
There would be half as many chromosomes. Each daughter cell would not have a complete set of chromosomes.
