Expert Solution & Answer

Summary Introduction

To determine:

The structure of the chloroplast where light reactions take place and also the site where the Calvin cycle takes place.

Introduction:

The chloroplast is a plastid organelle present in green leaves and algae. Chloroplast is the site of photosynthesis. Photosynthesis is a process in which sunlight is used to prepare the food nutrients. The prepared nutrients are stored in the form of starch. The chloroplast contains the chlorophyll, thylakoid, grana, and stroma.

Answer to Problem 1SQ

Correct answer:

The light reactions take place in the structures of the chloroplast called the thylakoid, while the Calvin cycle takes place in the stroma.

Explanation of Solution

The chloroplast is the organelle where photosynthesis takes place. The chloroplast is the double membrane bound organelle that contains the chlorophyll pigments, stroma, grana, and thylakoid. The thylakoid is present enclosed in the inner membrane of the chloroplast. It absorbs the light energy and provides green color to the chloroplast. The thylakoid membrane also contains the two photosystem unit or complex (PSI and PSII) where light reaction occurs.

The stroma is the fluid or aqueous layer that is present in the inner membrane of the chloroplast. The stroma consists of the stack of grana molecules. Various metabolic enzymes and proteins are also present in the stroma and they involve in the Calvin cycle. Thus, the dark reaction or Calvin cycle takes place inside the stroma of the chloroplast where ATP and NADH are synthesized.

Conclusion

The thylakoid membrane of the chloroplast is involved in the light reaction, while the stroma of the chloroplast involves in the Calvin cycle.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
