- True or False? In photosynthesis, both photosystems (I and II) depend on the energy of sunlight to excite a chlorophyll molecule until it releases an electron.independent and dependent variables of plant growing in Phototropism, Gravitropism, Chemotropism, Thigmotropism, Thermotropism and Hydrotropism.Modified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. The action spectrum of chlorophyll shows which wavelengths the chlorophyll absorbs best.
- Photosynthetic response curve to light for sun (solid line, N = 14) and shade leaves (dashed line, N = 21) of S. Why in this graph do we see shaded leaves have lower values compared to light leaves as PAR is increasing?True or false during the dark reaction of photosynthesis energy in the form of light is absorbed and converted to chemical energy in the form of a TPModified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. During photorespiration, Rubisco acts as carboxylase that catalyzes the reaction of RuBP and oxygen to form phosphoglycolate and PGA in the chloroplast.
- Dicsussion of the effect of dehyrogenase in the color intensity of metylene blue with fresh mungbean after incubation (dark blue) and after aeration (light blue) and without mungbean seedlings aafter incubation (dark blue) and after aeration (dark blue)Based on the vein density results and your knowledge of how the light treatments would impact the light reactions of photosynthesis, how can you explain the high starch concentration and low photosynthetic capacity value in symplastic loader individuals grown in low light and transferred to high light for one week prior to the measurements? Figure Legend: Figure 1. Spinach is an apoplastic phloem loader, while pumpkin is a symplastic phloem loader. An experiment was performed where spinach and pumpkin individuals were grown under three conditions LL - in low light environment (grey bars) HL- in high light environment (white bars) LL->HL in low light environment and then transferred to a high light environment for one week prior to measurements (dark stripes bars) The following measurements were performed on individuals of the two species growing in the three different treatments: vein density, starch content in leaves, and photosynthetic capacity. Statistical tests were performed…In cyclic photophosphorylation, NADPH is produced. True False
- True or False? The following is the correct sequence for the movement of electrons during the light-dependent reactions of plants: A) P680 --> P700 --> water --> NADP+ In cellular metabolism, photosynthesis uses solar energy to produce energy-rich organics; respiration breaks down energy-rich organics to synthesize ATPModified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. Chlorophyll a that is bright green in color is the pigment that initiates the light dependent reactions of photosynthesisTrue or False: 1.
