It can also be used to determine when lettuce seeds germinate (shown in the figure below Which scenario(s) above produce large amounts of the active form of phytochrome? A B A & C B & DOn a hot, dry day, plants close their stomata to conserve water. Explain the connectionbetween the oxidation of water in photosystem II of the light-dependent reactions and thesynthesis of glyceraldehyde-3-phosphate (G3PA) in the light-independent reactions. Predict theeffect of closed stomata on the synthesis of G3PA and justify the prediction. *Please answer the question being asked, not a question u wish I asked. And the answer should be short and concise.Question 5. What are the properties that favours the upward movement water through xylem?
- Part F - How to determine transpiration rates by the whole plant method Which of the following best explains why the plant in front of the fan lost more mass than the control plant in normal room conditions? The leaves of the plant in front of the fan had the highest initial water potential and therefore lost the most water. The control plant had lower initial water potential in the root area and therefore lost less water. The control plant had a lower initial mass and so lost water at a decreased rate. The fan rapidly moves water molecules away from the leaf surface, lowering the water potential.JT Model 2: Cross section of a leaf T 1. Label the following parts of the leaf on Model 2: ◆ Spongy mesophyll ◆ Palisade mesophyll Epidermis • Vascular bundle 2.
