Cell Structures
Small organelles that make protein
What are ribosomes?
Movement of a substance from high to low concentration directly across the lipid bilayer
What is diffusion?
Viruses can only do this inside a host cell
What is reproduce or replicate?
Type of transport that does not require energy
What is passive transport?
Type of cells that 1) have or 2) lack a nucleus and membrane-bound organelles
What are 1) eukaryotic and 2) prokaryotic cells?
Structure that surrounds the cell and controls what goes in or out
What is the cell membrane?
Diffusion of water across a membrane
What is osmosis?
A weakened virus introduced into the body to create an immune response that will fight off future infections is an example of this.
What is a vaccine?
What is ATP?
Something shared by plant cells and bacteria but not animal cells
What are cell walls?
Organelle that converts light energy into the chemical energy of glucose
What is the chloroplast?
Solution that has a low solute concentration (more water) and causes cells to swell or burst
What is a hypotonic solution?
A rabies-infected raccoon biting a human would be an example of this.
What is a vector?
What is to attach to cells?
3 things that plant cells have and animal cells don't
What are chloroplasts, large central vacuoles, and cell walls?
Types of projections that allow protists or other types of cells to move
What are cilia or flagella?
Solution that has a high solute concentration (less water) and causes a cell to shrink
What is a hypertonic solution?
Type of viral life cycle in which the viral DNA is replicated but remains inactive rather than immediately destroying the host cell
What is the lysogenic cycle?
Protein coat that protects the genetic material (DNA or RNA) of a virus
What is the capsid?
Four things shared by all cells
What are the cell membrane, DNA, cytoplasm and ribosomes?
Theory proposing that mitochondria and chloroplasts originated from bacteria that were engulfed (taken inside) by another prokaryotic cell
What is endosymbiotic theory?
Movement of a substance from high to low concentration across a membrane through a carrier protein
What is facilitated diffusion?
People becoming sick with nausea, diarrhea, and vomiting 1-3 days after exposure to a rotavirus is an example of this
What is the lytic cycle?
Organelle responsible for modifying, packaging, and shipping proteins in the cell
What is the Golgi body?
Two features shared by viruses and living things
What is genetic material (DNA or RNA) and the ability to evolve?
