Summary Introduction

To review:

The rate of photosynthesis increases in the leaf exposed to higher light intensities.

Given:

The graphs representing the rate of photosynthesis as a function of the intensity of light.

Introduction:

The process of photosynthesis is light dependent. Photosynthesis converts light energy into chemical energy. The rate of photosynthesis will increase if the leaves are exposed to the higher intensity of light.

Expert Solution & Answer

Explanation of Solution

Photosynthesis is a light-dependent process. This process uses light energy to produce carbohydrate and provide energy to plant for various metabolic activities taking place in the plant. This process produces carbohydrate by using light and carbon dioxide.

The rate of photosynthesis increases when there are higher light intensities. The leaves, which are exposed to the higher intensity of light, show high rate of photosynthesis. At low light intensity, the leaves will show a decrease in the rate of photosynthesis. The leaves with the larger surface area and high density of chlorophyll will show a high rate of photosynthesis as they can absorb more light.

From the given graphs, it is clearly visible that both the plants show increasing rate of photosynthesis in high intensity of light (shown by orange line) and rate of photosynthesis is low in low intensity of light (shown by purple line). The photosynthesis is directly proportional to the intensity of light, so the curves of photosynthesis increase with increasing light intensities.

This occurs because of the increase in the rate of light-dependent reactions, which in turn results in the increase in photosynthesis rate. However, the rate of photosynthesis is dependent on other factors like temperature and carbon dioxide concentration. Therefore, with further increase in light intensity, the photosynthesis rate does not rise further and eventually plateaus.

Conclusion

Thus, it can be concluded that photosynthesis is a light-dependent process. The rate of photosynthesis is directly proportional to the intensity of the light but to a certain extent only, as photosynthesis is controlled by various other factors also.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
