To examine: Whether the statement “After an electron has been removed by light, the positively charged chlorophyll in the reaction center of the first photosystem (photo system II) has a greater affinity for electrons than O 2 has” is correct or incorrect. Introduction: Photosystems that are present in the thylakoid membrane of plants are the functional and structural units of protein complexes that are involved in the photosynthesis process. It consists of two reaction centers, namely photosystem I (P700) and photosystem II (P680). For the oxygenic photosynthesis, both the photosystems are required.

Summary Introduction

To examine: Whether the statement “After an electron has been removed by light, the positively charged chlorophyll in the reaction center of the first photosystem (photo system II) has a greater affinity for electrons than O₂ has” is correct or incorrect.

Introduction: Photosystems that are present in the thylakoid membrane of plants are the functional and structural units of protein complexes that are involved in the photosynthesis process. It consists of two reaction centers, namely photosystem I (P700) and photosystem II (P680). For the oxygenic photosynthesis, both the photosystems are required.

B.

Summary Introduction

To examine: Whether the statement “Photosynthesis is the light-driven transfer of an electron from chlorophyll to a second molecule that normally has a much lower affinity for electrons” is correct or incorrect.

Introduction: Photosynthesis is a process by which carbon dioxide and water are used to produce glucose molecules using energy from sunlight. During this process, oxygen gas is evolved. Reactions of the photosynthesis take place in the chloroplast of the plant cell that contains the green pigment chlorophyll.

C.

Summary Introduction

To examine: Whether the statement “Because it requires the removal of four electrons to release one O₂ molecule from two H₂O molecules, the water splitting enzyme in photo system II has to keep the reaction intermediates tightly bound so as to prevent partly reduced, and therefore, hazardous, superoxide radicals from escaping” is correct or incorrect.

Introduction: Photosynthesis is a process in which carbon dioxide and water are consumed to produce food (sugar) and oxygen in the presence of sunlight. It converts the solar energy into chemical energy and stores it in the food produced. This food is consumed by other organisms.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

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…
