|
Define photoautotroph |
Makes food for themselves using light ex. Plants,algae |
|
|
Define heterotrophs |
Rely on other organisms for energy ex. Animals def |
|
|
Define chemoautotroph |
Make their own food without sunlight ex.organisms on bottom of ocean |
|
|
Formula for photosynthesis |
6CO2+6H2O--(light)-->C6H12O6+6O2 |
|
|
Which cells in plants do photosynthesis and where it's located |
Mesophyll: middle layer of cell in the leaves |
|
|
How O2 and CO2 are exchanged in plants. What cells are responsible for it. |
•exchanged through the Stomata (opening on bottom of leave) •guard cell control is stomata is open or close |
|
|
The arrangement of the parts of chloroplast |
Thylakoid:(individual disc in chloroplast) Granum:(stacks of thylakoids) Stroma:(fluid outside thylakoids) Lumen: (inside thylakoids) |
|
|
Some of the types of electromagnetic radiation the sun emits |
Visible light, UV rays, x-rays |
|
|
Know parts of wave(picture) and how energy, frequency, and wavelength are related |
Frequency: # of waves that past a point in 1 second Related: if wave length increases frequency decreases ex Big waves low energy low frequency |
|
|
Know which color of light have the most and least energy |
Red is lowest Violet is highest Roy G Biv |
|
|
What is an absorption spectrum |
Way to show wave length of light that pigment will absorb |
|
|
Know what type of light carotenoids absorb/ reflect and what plants are they most abundant in |
Absorb: V,I,B,G Reflect: Y,O,R Ex. Corn, carrot, tomatoes |
|
|
Know what type of light chlorophylls absorb/ reflect and what plants most abundant |
Absorbs most colors other than green Reflect green Ex. Green beans, broccoli |
|
|
Know the basic function of the two parts of photosynthesis and where they occur. Light Dependent Reaction |
•to take light energy and convert it into ATP&NADPH for light independent part(step 2) •happens across the membrane of the thylakoids |
|
|
Know the parts of a photosystem(ps) and what it's function is |
•2 proteins: where the pigment are stored (1 on each side) •reaction center in the middle •function: PS2 pigments absorb light energy and transfer it to the reaction center where it excites an electron and splits an H2O PS1 reexcites the electrons |
|
|
Produced by the light dependent reaction |
ATP&NADPH |
|
|
Where Light dependent reaction happens |
Stroma |
|
|
Starting reactants of the Calvin cycle/ light independent |
3CO2 and 3 RuBP |
|
|
How many CO2 are required for one cycle of the Calvin cycle |
3 |
|
|
Know the three phases of the Calvin cycle be able to describe what happens at each step |
1) carbon fixation: takes CO2+RuBP-->6C splits to 2 3C 2) reduction: the 3C molecule from step 1 gets reduced by gaining electron and becomes G3P 1 G3P is released to make glucose 3)regeneration: the 5 G3P are made to remake 3 RuBP |
|
|
How much energy is consumed for one Calvin cycle and at which steps |
Step 2:2 ATP and 2 NADPH for each carbon (6 for cycle ) Step 3: 3 ATP =9 ATP |
|
|
How much energy is consumed for one Calvin cycle and at which steps |
Step 2:2 ATP and 2 NADPH for each carbon (6 for cycle ) Step 3: 3 ATP =9 ATP |
|
|
What are the final products of one Calvin cycle |
3 RuBP and 1 G3P= 1/2 glucose |
|
|

|
|
What are the final products of one Calvin cycle |
3 RuBP and 1 G3P= 1/2 glucose |
|
|
How many Calvin cycles must occur to make 1 glucose |
2 |
