Ch 1
This is a statement based on evidence from many experiments or observations that is correct so far as we know. This can change.
What is a fact?
This describes a compound with a high pH.
What is basic?
This phrase means all cells come from other cells.
What is omnis cellula e cellula?
This is the color of light that is mostly reflected by plants.
What is green?
This is an organism’s maintenance of various continuous stimulus/response processes so that the organism remains within life-sustaining limits.
What is homeostasis?
This is the lowest level of biological organization that exhibits all six characteristics of life
What is the cell?
These are the four biomolecules.
What are lipids, carbohydrates, proteins, and nucleic acids?
This is transport that requires no input energy across the cell membrane.
What is passive transport?
This is the organelle where photosynthesis takes place.
What is the chloroplast in plant cell?
This is a molecule that has an electrical charge because it has gained or lost one or more electrons.
What is an ion?
This is a mental model or representation that accounts for a large number of scientific facts in an organized way.
What is a theory?
Starch, glycogen, cellulose, and chitin are types of this biomolecule.
What is a carbohydrate?
There are three major types of this: primary active transport, secondary active transport, and bulk transport.
What are the three main types of active transport?
This is the purpose of cellular respiration.
This made mostly of phospholipids with embedded proteins. This flexible boundary regulates what goes in and out of the cell.
What is the cell membrane?
This is the prevailing theory of how life started. Life always comes from life.
What is biogenesis?
This substance is unique - as a solid it is less dense than as a liquid.
What is water?
This is the organelle that contains DNA and makes ribosomes.
What is the nucleus?
This type of chemical reaction releases heat.
What is an exothermic reaction?
This facilitates or expedites a chemical reaction without itself being one of the reactants or products. It does this by lowering the activation energy necessary to initiate the reaction.
What is a catalyst?
This is Aristotle's theory that organisms could randomly come into existence.
What is spontaneous generation?
This subatomic particle exists on the outermost energy level in orbitals on the atom.
What are electrons?
These are the three types of endocytosis.
What is phagocytosis, pinocytosis and receptor-mediated endocytosis?
These are the four steps to cellular respiration.
What is glycolysis, oxidation of pyruvate, Kreb's cycle, and oxidative phosphorylation?
This serves to hold cells together to form tissues in the body and protects the cell membrane. It is composed of glycoproteins and the protein collagen.
What is the extracellular matrix?
