What is the purpose of Alveoli? 

What is reoxygenates blood?

100

What is lost during transpiration?

What is water?

200

What object in the lungs allows for gas exchange to occur?

What is Alveoli?

200

How does gas always move? 

What is down a pressure gradient from an area of high pressure to an area of low pressure? 

200

Where is the Alveoli?

What is the end of the branches of bronchioles?

200

When the stomata is closed photosynthesis is....

What is decreased?
300

What does the trachea divide into 2 of?

What is Bronchioles? 

300

What is intercostal muscles contract during inhalation?

What is external intercostal muscles?
300

Why are Alveoli effective at gas exchange?

What is they have a large surface area to volume ratio?

300

What is the purpose of the guard cell?

What is to open or close the stomata?

300

What are the four factors that can affect transpiration?

What is humidity, temperature, light intensity, and air movement? 

400

What is the mammalian adaptation for gas exchange?

What is lungs?

400

What are the steps involved in the inspiration process?

What is

1. The diaphragm contracts and flattens?

2. External intercostal muscles contract?

3. Ribcage moves upwards and outwards?

400

What surrounds the Alveoli to assist in the distribution of oxygen?

What is Capillary network?

400

Where are chloroplasts stored?

What is Palisade mesophyll? 

400

Why does higher humidity reduce rate of transpiration?

What is water vapour on the outside of the Leaf due to humidity disrupting the concentration gradient?

500

What is the adaptation for gas exchange that many fish have?

What is gills? 

500

How does exhalation occur?

What is the internal intercostal muscles contract to pull the ribs down and abdominal muscles push organs upward decreasing volume in the chest and pushing out air?
500

What if the Alveoli was less effective at gas exchange?

What is the Alveoli would have less volume to surface area ratio, it would be less efficient in resupplying oxygen to blood in an effective manner, this could lead to widespread breathing issues among humans?
500

What is Xylem; “forms vascular bundles that transport water and minerals from the roots to the leaves, and sugars from the leaves to other parts of the plant.”?

500

Why is the loss of water concerning for the plants?

What is the reduction of turgor pressure due to less water causing plants to Wilt and become unsupported?
