Diffusion & Gas Exchange
Key Words:
Gas Exchange
Stomata/Stoma
Diffusion
Net Movement
Concentration of Gasses
Diffusion:
Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration.
Stoma/Stomata:
Tiny holes in leaves, they are used for gas exchange, water evaporation and photosynthesis.
Gas Exchange:
In this case, it mean by high concentration/particles of…
Concentration:
Concentration is the term to describe how dense the particle of a gas is in an area.
High concentration: Lots of partice in a place.
Low concentration: Not much particle in a place.
Net Movement:
It is the process which a gas move from a high concentrated place to a low concentrated place. Usually they will move in opposite direction and bump into each other. There are times when majority of gasses move in one direction.
Carbon Dioxide and Oxygen are made up of tiny particles or atoms.
Carbon dioxide is made up of 2 atoms of oxygen and 1 atom of carbon :
Oxygen is made up of 2 atoms of oxygen:
These two gasses are really easy to break apart.
Diffusion of Gasses:
In this case, it is just carbon dioxide moving into the stomata into the plant’s cell. And oxygen moving out of the plant cell through the stomata.
Gas Exchange:
→ Oxygen is a waste product.
