1. Describe the overall changes in matter that occur during the light- independent reactions. What does the plant start with and what does it end with? What is the source of energy that powers this change? 6 6 ADP ATP Light-Independent Reactions 60 CO₂ 00000 10 12 12 STROMA 12 ATP 12 ADP 12 NADPH

Stomata can open and close in order to modulate the transpiration stream and allow for exchange of oxygen and CO2. Stomata OPEN by…

Positive phototropism is one of the most obvious aspects of plant growth but the mechanism behind it required considerable experimentation to finally explain. Briefly describe how positive phototropism works, including the processes, structures and/or molecules involved.

A mutation causes the vascular cambium in a plant to stop working How does this impact cellular respiration?  ANSWER CHOICES ARE IN THE PHOTO. thanks

Stomatal opening is induced by…

2. If a plant was deficient in nitrogen, name which complexes, molecules, and/or parts of the light harvesting and photosynthetic apparatus you think will be affected and explain why

students are asked to pair a plant structure to its physiological function and give evidence for why that structure is important for the process they describe Anne The root hairs are used to pull in sugars available in the soil that give the plant energy for growth and reproduction Jamil : The phloem is needed for cellular respiration as transports the carbon dioxide the leaves in order to perform cellular respiration Shantal The cambium is important for photosynthesis because it allows water into the plant is needed as a reactant for photosynthesis Enrique The guard cells are needed during transpiration because they open and close to regulate the gases that enter and leave the plant student correctly described a plant structure and its physiological function?

Match how each adaptation supports photosynthesis for a specific type of plant. f. mesophyll g. C3 a. Stomata close. b. CAM h. malate temperature d. leaf thickness C. i. PEP j. 0, е. C4 66. Which type of plant works best in cool climates? 67. Which type of plant uses two cells for fixing carbon into carbohydrates? 68. Which molecule combines with CO, to form oxaloacetate? 69. Which factor reduces the rate of photorespiration? 70. Which factor suggests a strategy to retain water in a dry environment

If plants need CO2 to construct glucose (by photosynthesis), why is the rising level of CO2 in the atmosphere cause for concern? You’d think more CO2 would accelerate plant growth, and that would be a good thing.
