Photosynthesis is a process in which the primary producers convert the sunlight and chemical molecules into usable forms of energy. This usable form of energy is stored in organic compounds, such as sugars. The primary producers convert carbon dioxide and water into glucose. The more synthesis of sugar leads to the accumulation of more biomass.

Answer 1

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Summary Introduction

Introduction: Photosynthesis is a process in which the primary producers convert the sunlight and chemical molecules into usable forms of energy. This usable form of energy is stored in organic compounds, such as sugars. The primary producers convert carbon dioxide and water into glucose. The more synthesis of sugar leads to the accumulation of more biomass.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer: The amount of energy that is fixed during photosynthesis is known as “gross primary productivity”. Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer:

The energy is measured in terms of production and it is stored in the biomass of the organism. Biomass is defined as a quantitative estimate of the total mass of living organisms. It is measured in grams or kilograms per square meter. Gross primary production is equivalent to the carbon fixed during photosynthesis. Therefore, it is the cumulative energy stored in the organic molecules. The more the amount of carbon that is fixed, more the biomass produced. Hence, gross primary production is the amount of carbon fixed during photosynthesis.

Option d. is given as “gross primary production”.

The photosynthetic organisms, for example, plants, algae or cyanobacteria represent the first or primary trophic level, and their production is known as gross primary production. Hence, the correct answer is option d.

Reasons for incorrect answer:

Option a. is given as, “net primary production”.

Net primary production is defined as the gross primary production minus the energy used during cellular respiration of photosynthetic organisms. Hence, option a. is incorrect.

Option b. is given as, “biomagnification”.

The tendency of certain chemicals to concentrate on higher trophic levels in the food chain is known as biomagnification. Hence, option b. is incorrect.

Option c. is given as, “trophic-level transfer efficiency”.

Trophic-level transfer efficiency is defined as the amount of energy present at one trophic level that is acquired by the trophic level above and incorporated into the biomass. Hence, option c. is incorrect.

Option e. is given as, “production efficiency”.

Production efficiency is defined as the percentage of energy assimilated by an organism that becomes incorporated into new biomass. Hence, option e. is incorrect.

Hence, the options a., b., c., and e. are incorrect.

Conclusion

Hence, the amount of energy that is fixed during photosynthesis is known as gross primary production.

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.
