The Gas Exchange Systerm Flashcards
(19 cards)
Howdo plants breathe?
Cellular Respiration
found on the outer surface of epidermal cells
Stomata
What are the role of stomata
Gaseous exchange, as well as transportation, are their responsibilities
Where are Lenticels found?
Found on the inner surface of the cells.
What are the three types of respiration?
Respiration in roots-stomata, leaves, stems-lenticels
What are the parts of stomata
Nucleus, Chroloplast, Vacuole, Guard wall, Cell Wall
What is the force within the cell that pushes the plasma membrane
Turgor Pressure
Should a plant in stomata be open or closed?
open during the day to favor CO2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water
Respiration in roots
Roots, Air, Water, and Soil
What are the three steps involve in gas exchange?
Ventilation, Gas exchange, Circulation
What is ventilation
Air is brought into the respiratory organ
What is gas exchange
Oxygen is taken in and carbon dioxide is expelled
What is circulation
Gas is moved to (and from) the tissues via a circulatory fluid
What are the mechanism of Gas exchange?
Direct Diffusion, Tracheae, Lungs, Skin, and Gills
This mechanism of gas exchange is for small organisms like cnidarians and flatworms, which are less than 1mm in size.
Direct Diffusion
What gas exchange mechanism is where insects breathe through a system called tracheae, which are small tubes that carry oxygen through their bodies.
Tracheae
This Mechanism of gas exchange is where small animals have capillaries, right under their skin.
Skin (cutaneous respiration
Made up of thin, folded tissues that look like tiny branches.
Gills
There are two of these inside the body of a human with different sizes.
Lungs
