Osmosis
In osmosis, this substance moves across the semipermeable membrane.
What is the solvent/water?
In diffusion, particles move from an area of __________ concentration to __________ concentration.
What is high concentration to low concentration?
_________ are the most basic unit of life.
What are cells?
What is a particle?
A small, non-living building block that makes up all matter.
This is the process where particles move from an area of high concentration to an area of low concentration.
What is diffusion?
In osmosis, water moves towards an area of high _______ concentration.
What is solute?
Diffusion occurs _______ in a warm solution.
What is faster?
_________ are formed of groups of similar cells that have the same specific function.
What are tissues?
Particles have the most space between them in this state:
What is gas?
The process where solvent particles move across a semi-permeable membrane to an area of high solute concentration.
What is osmosis?
When a cell is placed into a hypertonic solution the water will _______ the cell.
What is exit/leave?
Diffusion is important in the body because:
It allows our cells to bring in nutrients, water, and oxygen, while releasing waste products like CO2.
________ is a structure made up of different tissues that work together to perform functions in the body
What are organs?
Particles are always_______
What is moving?
The cell membrane is a ____-__________ membrane.
What is semi-permeable?
When a cell has the same solute concentration as the outside environment, it is considered to be _____tonic.
What is isotonic?
When diffusion has finished, this term describes the state where molecules are evenly spaced out and there is no net movement.
What is equilibrium?
___________ is a collection of organs that work together to perform a specific function for the body
What is an organ system?
When a substance is placed into a colder environment, the particles will______
What is slow down?
Water moves ____________ the cell when the cell is hypertonic.
What is into the cell?
Explain why it would be bad for human cells if we drank salt water.
The environment that the cells are in would become hypertonic, drawing moisture out of our body cells.
Name 3 factors that affect the rate of diffusion.
What is: temperature, the concentration gradient, distance, the medium, the surface area, the mass of the particles, the solubility of the particles?
Name 3 organ systems
Many options (digestive, cardiovascular, respiratory, musculoskeletal, excretory, neurovascular, etc.)
Explain how the Particle Theory can be used to explain diffusion (think about particle motion and space)
Particles are always moving and will move into the empty spaces (low concentration) until they are evenly spread out.
Osmosis and diffusion are types of _________ transport.
What is passive?
