Diffusion is living things or non living things?
Non living things
Definition of diffusion
The movement of molecules/ions from high concentrations to low concentrations
What is this process called
The process of spreading out diffusion
What state of liquid will kill living cells and enzymes
Boiling
Eg.potato (living things) in sugar solution ( contain water ) . What is this process called?
Osmosis
Is osmosis living things or non living things?
Living things
What is the example of “permeable” ?
Cell membrane
What do all living things have?
Cell membrane
What is the definition of osmosis ?
The movement of water molecules from high water potential to low water potential across selectively permeable membrane.
List 3 solutions of osmosis
Hypertonic , isotonic and hypotonic
List 2 characteristic of hypertonic
It is low water potential and very concentrated
List 2 characteristic of isotonic
It dilutes high water potential and has same concentration
Definition of isotonic
Same concentrations with the concentrations in cells
Definition of hypertonic
It is a concentrated solution and has less water ( hence low water potential )
Definition of hypotonic
It dilutes solution and has more water ( hence high water potential )
Is active transport living things or non living things?
It is living things
What is the definition of active transport?
Movement of molecules/ions from low concentration to high concentrations across selectively permeable membrane using energy
Active transport needs energy through what ?
Through selectively permeable membrane
What is the movement of diffusion?
High to low concentrations
What is the movement of osmosis ?
High water potential to low water potential
What is the movement of active transport?
Low to high concentrations
Does diffusion and osmosis has energy from respiration?
Both has no energy from respiration
Does active transport has energy from respiration?
Yes active transport has energy from respiration
Why active transport has energy from respiration?
It needs oxygen for respiration to release energy
Describe what’s moving in diffusion
Particles , molecules and ions
Describe what’s moving in osmosis
High water potential to low water potential
High water potential to low water potential
Describe what’s moving in active transport
Low concentrations to high concentrations
Does osmosis and active transport need cell membrane?
Yes they both need cell membrane
Does diffusion need cell membrane?
No
Does diffusion and osmosis need oxygen?
No
Does active transport need oxygen?
Yes
