In which plant structure does photosynthesis take place?
Chloroplast
What is the name of the green pigment inside plants?
chloropyll
In which leaf cells do most photosynthesis take place?
Palisade Cells
carbon dioxide + water --> ?
glucose + oxygen
Where does the energy for photosynthesis come from?
sunlight
Is photosynthesis endothermic or exothermic?
endothermic
What is the term that describes the feature that stops a reaction rate from getting any faster?
Limiting Factor
If a leaf is in the shade, would you expect it to have more or less chlorophyll?
More
If CO2 concentration is increased - what shape graph will the rate of respiration make?
increase and then plateau
If light intensity is increased - what factors might limit the rate of reaction?
CO2, Water, temperature
What shape graph will demonstrate the affect increasing temperature have on the rate of respiration
bell shaped curve - peak at optimum
What makes the temperature graph rate low when it is too cold?
kinetic energy
what makes temperature graph lower when it is too warm?
denatured enzymes
How could we make this investigation more PRECISE
collect and measure the volume of gas in a syringe/cylinder
If we move the flask closer to the lamp - how will this affect the rate of bubbles?
Increase
What other variables must be kept the same in this investigation?
species/age/surface area of plant, volume of water, temperature, pH
