Transpiration Lecture Notes

Transpiration is the movement of water through the plant.

Adhesion prevents gravity from pulling the column of water molecules from being pulled back down to the roots, used in the xylem wall.

Water wants to move out of the leaves to the air because of the lesser amount of water in the air. No matter how high the tree is the same process will occur.

Roots osmosis into root hairs.

Xylem cohesion and adhesion.

Leaf evaporation from stomata.

Difference in temperature and humidity will change the amount that will be transpired.

Changes in relative humidity and hormones from the roots which are sensing how much water is in the soil.

Transpiration and photosynthesis need to be in balance because if you do not have enough water there will be much less transpiration.

Higher the temperature the more water molecules a leaf can hold.

Plants can create heat for themselves when oxidizing sugars.

Wind increases transpiration to a certain point, around 30-40mph the stomata close and stops transpiration completely.

To much Co2 will cause the stomata to close.

Use pedometer to measure transpiration.

Punch 5 and 2 at the same time then punch 3 then 1 then pull to get into the green house

Reading Response The Ionian Enchantment

The Ionian Enchantment chapter of the book Consilience is about how the author progressed from what he was when he was younger and how he started to question everything he has known. The author puts the bible in a view that most people do not see or want to believe in. He looks at the bible from when he was younger and brought up as a baptist christian to what he has learned in the scientific communities  and questions why we follow the words of a book written two thousand years ago. Although he has not lost his faith he questions what is written more and more. The Ionian Enchantment is something that he has discovered for him self and it means the belief in the unity of the sciences and conviction in them. In this chapter he talks about the source of the Ionian Enchantment saying that the sciences and religion are intertwined and it should be used for the unification of knowledge not separated belief.

Reading Response Two Cultures

 In Chapter one the author talks about the differences between literary writers and scientists. The author talks about how literary writers see things differently than scientists in a way that scientists can not understand. Literary writers talk about problems in the world through writing but they also have more emotion in their work and in their opinion scientists do not quite understand what they are supposed to feel in the words. non-scientists believe that scientists are too optimistic when it comes to the way people are. Just as the literary writers scientists have discovered things that literary writers do not understand as well. Scientists believe that the literary intellectuals are lacking in foresight in particular with the problems of other men and women. Scientists believe they can solve every problem but they also see what non-scientific minds mean by what they say. Both of the communities believe just because the individual life is generally poor does not mean that they will not be able to be socially happy. There are things that both groups agree on and that we can fix and that is keeping people fed and not focus on the tragedy that accompanies not being able to be fed.

Research on transpiration


Warm,windy, and drier air increase transpiration rates.

Possible use of small fan maybe a heat lamp near our plant

Questions for transpiration

Question One: Does heat or cold create a more suitable environment for transpiration to occur?

Question Two: Will certain designs be more effective in collecting the water?

Question Three: Howill we measure the water?

Question Four: Howill the plants handle cold weather

Question Five: How much water will the plant require and how much water will it take to get maximum transpiration

Question Six: Would using a heat lamp help increase transpiration significantly?
