Question #1
What is passive transport?
The answers are
a. the size of the molecule can fit through the cell membrane.
b. the molecule does not have a charge.
What are the two criteria necessary for diffusion to happen?
This is the pressure that is found inside the cell pulsing out.
What is turgor pressure?
When energy is required to move molecules.
What is active transport?
Evolution of an organisms based on the best traits for the environment.
What is natural selection?
The type of movement that molecules of passive transport experience.
What is the random movement?
The way molecules move in passive transport. (in terms of concentration)
What is from high to low concentration?
The pressure that is on the outside of the cell pushing in on the cell membrane.
What is osmotic pressure?
When large molecules leave the cell with the help of the golgi apparatus.
What is exocytosis?
A physical trait or characteristic.
What is a phenotype?
This type of passive transport occurs when the movement is with small molecules and ones that are not water.
What is diffusion?
Water always moves towards this type of solution.
What is Hypertonic?
The overall pressure on the cell.
What is diffusion pressure?
When large molecules are brought into the cell.
What is endocytosis?
Smallest part of a living thing that still retains life properties.
What is a cell?
This type of passive transport is with water only.
What is Osmosis?
A Hypertonic solution has more of the these than a Hypotonic solution.
What is molecules?
Calculating the diffusion pressure, when the osmotic pressure is 10 atm and the turgor pressure is 18atm.
What is the diffusion pressure is -8atm?
Movement of solids into the cell.
What is phagocytosis?
A way to measure a population based on counting a small, random selection of a population to estimate the total population. Only done on non moving organisms.
What is random sampling?
A type of passive transport that required proteins to help slightly larger molecules get through the cell membrane.
What is facilitated diffusion?
What is isotonic?
A negative diffusion pressure.
What is the water leaving the cell?
Movement of fluids into the cell.
What is pinocytosis?
A factor that is not living , such as water temperature, that affects the life of an organism and the population.
What is abiotic?
