Diffusion Basics
In diffusion, particles move from areas of _____ to _____ concentration.
High to low
What is osmosis specifically the movement of?
Water
Where does the eye get oxygen from?
From the atmosphere by diffusion.
Name the 2 products of photosynthesis.
What are glucose (sugar) and oxygen (O2)?
Name the 2 reactants of cellular respiration .
What are oxygen (O2) and glucose (sugar).
What is the term for a balanced concentration on both sides of a membrane?
Equilibrium
What direction does water move in osmosis?
From high to low water concentration
Which organ absorbs nutrients using diffusion?
The small intestine
The organelle where photosynthesis takes place.
What is a chloroplast?
The (Blank) is the location of this aerobic process.
What is the mitochondria?
Why does diffusion require no energy?
It happens naturally due to particle motion
What happens to a plant cell when it’s placed in pure water?
Water enters the cell and it swells
What happens in the lungs due to diffusion?
Oxygen enters blood, CO₂ exits.
The main function of photosynthesis (main product).
What is glucose?
The main function of cellular respiration (main product).
What is ATP (energy)?
Which gas diffuses into the eye from the atmosphere?
Oxygen (O₂)
What happens to animal cells when too much water enters by osmosis?
They can burst or lyse.
What organ uses osmosis to balance water and waste?
The kidney
The pigment found in green plants that absorbs sunlight.
What is chlorophyll?
These kind of cells have mitochondria.
What is Eukaryotic?
What process allows CO₂ to exit the body through the lungs?
Diffusion
Why is osmosis important for cells?
It helps maintain balance by controlling water movement in and out.
What happens if you place a raisin in water overnight?
It swells as water enters by osmosis.
The balanced equation of photosynthesis (number of each molecule needed).
6CO₂ + 6H₂O (+ light energy) → C₆H₁₂O₆ + 6O₂
The balanced equation of cellular respiration (number of each molecule needed).
C6H12O6 + 6O2 → 6CO2 + 6H2O [+ ATP]
