Diffusion is the natural movement of molecules from:
Areas of low concentration to areas of high concentration
Areas of high concentration to areas of low concentration
Cold to hot environments
Gaseous to liquid environments
Why is diffusion so important in biology?
It's the basic power source for most types of cells
It allows substances to move across cell membranes
It prevents toxins from entering our bodies
Without diffusion, cell division could not take place
Which gases move into and out of blood in the lungs by diffusion?
Nitrogen and Oxygen
Oxygen and Carbon Dioxide
Nitrogen and Carbon Dioxide
Argon and Nitrogen
Leaves are wide and flat
to absorb light energy for photosynthesis.
to create a large surface area and to absorb
as much light as possible.
for efficient gas exchange.
to allow gases to move in and out.
Leaf cells contain chlorophyll in chloroplasts
to absorb light energy for photosynthesis.
to create a large surface area and to absorb
as much light as possible.
for efficient gas exchange.
to allow gases to move in and out.
Air spaces inside the leaf give the cells a large surface area to volume ratio
to absorb light energy for photosynthesis.
to create a large surface area and to absorb
as much light as possible.
for efficient gas exchange.
to allow gases to move in and out.
Leaves have holes, called stomata, on their underside
to absorb light energy for photosynthesis.
to create a large surface area and to absorb
as much light as possible.
for efficient gas exchange.
to allow gases to move in and out.
