Plant Science(material)- Unit 1 grade 10

Transpiration Types + percentages

Stomatal - 98%

Cuticeluar - 1%

Lenticellular - 1%

Maple syrup, How is it made?

1. Tapping trees - drill a hole and then put a spile in it, and place a bucket under that - to catch sap - then goes to a tube system if its a big facility

2. Leads to a vacuum collection system to an extractor

3. Then bring up sugar content up to 8%

4. Gets pushed through filter fast and hard to get water out

5. Preheat sap

6. Boil - then gets into a pipe to transfer into filters - but before the pressure filters they keep an eye on the sugar content level

7. Pressure Filter - removes naturals sands

8. Gets bottled by a machine

When is tapping season?

Temps above freezing during the day, below freezing at night

What is the goal of photosynthesis?

For the plant to make food for its self

Chloroplasts, what do they do?

Where photosynthesis occurs, chloroplasts are found in the guard cells, palisade, and spongy mesophylls.

Two cycles within photosynthesis

Calvin and light reaction

Reactants of water light and Co2 as well as products?

Light + water = ATP + NADPH, the product is oxygen and glucose

What role does light play in photosynthesis?

Used to power movement of an electron in an electron chain - through proteins

What happens if there is no Co2 in photosynthesis?

if stomata is closed Co2 can’t get in, if there is no co2 it shuts down the process of photosynthesis, or photo respiration could happen - oxygen could come into the cycle, makes something the plant coan’t use and the plant has to use more energy to break that down.

Goal of respiration?

Turn glucose into usuable form of energy Reaction C6H12O6 = ATP co2 + h20?

Water movement

Where are chloroplasts found?

What is the photosynthetic reaction?

H20 + co2 + light energy = o2 + C6H12o6

Light reaction where does this happen

Inside the thylakoid

Where is the Calvin cycle?

Stroma

Reactants of photosynthesis

Light water carbon dioxide

Products of photosynthesis

Oxygen and glucose

What happens during the light reaction?

Water and light go into the thylkaoid and produce oxygen(waste product) and make NADPH and ATP

What happens in the Calvin cycle

ATP energy comes in from light reaction, co2 comes in and glucose comes out

Goal of respiration?

To turn glucose into a usable form of energy

Respiration reaction/Krebs cycle equation

C6h12o6(glucose( + o2 =co2 + ATP + h20
