Cellular Biology
This process allows molecules like oxygen to move from high concentration to low concentration across a cell membrane.
What is diffusion?
This tool is used to magnify organisms too small to see with the naked eye.
What is a microscope?
This organelle contains your genetic material and controls the cell’s activities.
What is the nucleus?
This organ is responsible for pumping blood throughout the body.
What is the heart?
This plant process uses sunlight, carbon dioxide, and water to make glucose.
What is photosynthesis?
This term describes the build-up of harmful substances like DDT in organisms higher up the food chain.
What is bioaccumulation?
These single-celled organisms reproduce by binary fission and can be helpful or harmful.
What are bacteria?
This is the name for a version of a gene.
What is an allele?
This part of the blood is responsible for carrying oxygen.
What are red blood cells?
This part of a plant is responsible for absorbing water and anchoring it to the ground.
What is the root system?
This special type of membrane allows only certain small or uncharged molecules to pass through.
What is a semipermeable membrane?
This method involves heating liquids to kill harmful microorganisms without affecting taste.
What is pasteurization?
This cell division process results in gametes with half the number of chromosomes.
What is meiosis?
This component of blood is responsible for clotting.
What are platelets?
These tiny openings on the underside of a leaf open and close to control gas exchange.
What are stomata?
This molecule acts like cellular gasoline, powering reactions and active transport in cells.
What is ATP?
This term describes anything that causes disease, like bacteria, viruses, or fungi.
What is a pathogen?
This term describes an organism with two identical alleles for a trait.
What is homozygous?
These organs are responsible for filtering waste from the blood.
What are the kidneys?
This hormone helps plants respond to gravity and light by controlling cell elongation.
What is auxin?
In a lab, a student places red blood cells in distilled water and observes them burst. This outcome demonstrates this type of solution.
What is a hypotonic solution?
This structure is found in viruses but not in living cells, making them non-living.
What is a capsid?
This technique allows scientists to cut and move genes from one organism to another.
What is recombinant DNA technology?
This part of the brain controls coordination and balance.
What is the cerebellum?
These are the two generations that alternate in the life cycle of mosses and ferns.
What are the gametophyte and sporophyte generations?
