Observations with senses
what is qualitative?
Membrane bound structures in Eukaryotes.
What are organells?
Some substances can cross the membrane more easily than others.
What is selective permeability?
All of the chemical reactions in an organism.
What is metabolism?
Movment of water.
What is osmosis?
Measued using instraments
What is quantitative?
Binds all cells.
What is a plasma membrane?
Transport of a molecule that does not require energy from the cell becasue a solute is moving with the concentration gradient.
What is passive transport?
A series of chemical reactions that either build complex molecules or break down complex molecules.
What are metabolic pathways?
the ability of an extracellular solution to casue a cell to gain or loose water.
What is tonicity?
Predictions that can be tested by recording more observations or experiments.
What is a hypothesis?
Are monomers of proteins.
What are amino acids?
The diffusion of water down its concentration gradient across a selctively permiable membrane.
What is osmosis?
Pathways that relase energy by breaking down complex molecules into simpler compounds.
What are catabolic pathways?
The value that appears most often in a data set.
What is mode?
Specific results are derived from general premises.
What is deductive reasoning?
Large vesicles that stem from the ER and Golgi.
What are vacuoles?
Diffusion of molecules through the membrane via transport protein.
What is facilitated diffusion?
Pathways that consume energy to build complicated molecules from simplier compounds.
What are anabolic pathways?
A polymer with many sugars joined via dehydration reactions.
What are polysaccharides?
A hypothesis in which the researcher tries to disprove, reject or nullify.
What is a null hypothesis?
The theory that explains the similarities mitochondria and chloroplasts have to a prokayote.
What is the endosymbiont theory?
Provide a channel for molecules and ions to pass.
What are channel proteins?
Uneaqual concentrations of ions across the membrane results in an electrical charge.
What is membrane potential?
The repeating units that make up polymers.
What are monomers?
