|
Heliotropism |
The diurnal motion or seasonal motion of plant parts (flowers or leaves ) in response to the direction of the sun |
|
Front (Term) |
B |
|
|
Term for plant development |
Alternation of generation |
|
|
Bigger leaf means what |
More surface area, better to get light Sade plants |
|
|
Sun plant leafs |
Little |
|
Front (Term) |
Sun leaves have less thylakoid |
|
|
Rubisco why is it important |
Carbon fixation |
|
|
What can rubisco react with |
Carboxylase oxyenase |
|
|
What controls gas exchange |
Stomta |
|
|
How do plants perform photosynthesis in arid areas ? |
Why not open stomata only at times when it’s not super hot |
|
|
Why does photorespiration? |
When CO2 goes down When temp go up |
|
Front (Term) |
Yes |
|
|
Front (Term) |
Yes |
|
|
What’s acclimation |
Change in phenotype in response to changes in environment |
|
|
How would you solve the problem with photorespiration |
C4 metabolism |
|
|
What happens in Mesophyll cell |
Carbon fixation by pep carboxylase Pep adds co2 to 3c molecule to form 4c |
|
|
What happens in the bundle sheath cell |
Rubisco is sequestered Decarboxylation of c4 molecule to release co2 |
|
|
Why do you think c3 plants evolves |
More efficient Trade off in evolution |
|
|
How do plants perform photosynthesis in arid areas ? |
Why not open stomata only at times when it’s not super hot CAM Crassulacean Acid Metabolism |
|
|
Cam photosynthesis at night |
Stomata are open, gas exchange occurs CO2 is fixed to a 4c molecule (c4 acid) in the cytoplasm The 4c molecules is transported to the vacuole for storage |
|
|
Cam photosynthesis During the day |
Stomata are closed, gas exchange stops The 4c molecule is transported from the vacuole to the Chloroplast The 4c molecule is split into a 3c molecule and CO2 |
|
|
At what point during the day will ph be lowest in the cell of a cam plant |
Sunrise |
