How are cellular respiration and photosynthesis ..

Furthermore, even before lysis, the infection of microbes alters host metabolism. Virus-induced changes in host metabolism can be so significant that the resulting infected particle is, biochemically and metabolically, a very different cell. For example, phage-infected cyanobacteria exhibit a higher rate of photosynthesis than their noninfected counterparts, presumably changing their rate of fixation of carbon from the environment until they are eventually killed by the infection. Bacterial cells undergoing active phage infections can also have altered distributions of other major elements, such as nitrogen and phosphorus, making them biochemically unique.

plants would use up all the #CO_2# and starve to death

Photosynthesis mainly takes place in the palisade mesophyll cell in the leaves of plants.

This can result in serious disorders and even cell death

Consider the question: How does the population size of a particular bacterial lineage depend on interactions with a particular set of viruses? Mathematical models deconstruct interactions between hosts and their environment, between viruses and hosts, and between viruses and the environment. For example, the infection of a marine cyanobacterium by a cyanophage can lead to lysis in approximately 12 hours. The net effect is the death of a host cell, the release of ~50 progeny viruses, and the release of organic material from the original cell as both virus particles and cellular debris. Hence, a model may ignore the complicated intracellular dynamics and focus on the output, breaking down the entire process in terms of a representative “chemical” reaction, such as 1 Host + 1 Virus = 50 Viruses. Then, the population dynamics of hosts and viruses can be derived from these reactions just as one would derive chemical reaction kinetics.

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....

These two subunits enable eukaryotic cells that contain them to conduct respiration and photosynthesis, respectively.

Nucleus: this contains genetic make (the DNA), which controls the activities of the cell.

Chlorophyll absorbs the light energy needed to make photosynthesis happen. It is important to note that not all the color wavelengths of light are absorbed. Plants mostly absorb red and blue wavelengths — they do not absorb light from the green range.

For more information on cell death see reviews (for example from: Nomenclature Committee on Cell Death) - intrinsic and extrinsic pathway.

The test will be to find out the relationship between light intensity (voltage) and the rate of photosynthesis.

The death of a host cell and the release of viral progeny are but one part of the story of how viruses affect the ocean ecosystem. Lysis of microbes also releases carbon and other organic nutrients, previously tied up as cellular materials, back into the environment. Marine microbes can assimilate these organic materials, leading to a paradoxical consequence of viral infection: the death of one host may indirectly benefit other microbes.

Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells....

It is apparent that we still have much to learn about the rich and dynamic world of ocean microbes and viruses. For example, a liter of seawater collected in marine surface waters typically contains at least 10 billion microbes and 100 billion viruses—the vast majority of which remain unidentified and uncharacterized. Thankfully, there are an increasing number of high-throughput tools that facilitate the study of bacteriophages and other microbe-infecting viruses that cannot yet be cultured in the laboratory. Indeed, studying viruses in natural environments has recently gone mainstream with the advent of viral metagenomics, pioneered by Forest Rohwer and colleagues at San Diego State University in California.

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis

All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight.
