Answer:

Teichoic acids

Explanation:

Teichoic acid has a negative charge  due to the presence of phosphate in their structure. Since Teichoic acids forms part of Bacterial cell wall where it is linked to the underlying peptidoglucan or plasma membrane. This gives the Gram Positive bacteria a negative charge.

The negative charge makes the Teichoic acid to serve as a Cation sequestering mechanism

Gram negative cell wall does not contain teichoic acids. .

Answer: They are called Teichoic acids.

Explanation:

Teichoic acids are polymer that are rich in posphate present in gram positive bacteria. Techoic are negatively charged and there presence in the peptidoglycan wall or plasma cell make the gram positive to have a negative charged bacteria cell. Teichoic acids are negatively charged due to the phosphate structure. They function in determine bacteria cell wall and cell division. Examples of gram positive bacteria with teichoic acids is staphylococcus.

What is the purpose of each organism being able to carry out either cellular respiration or photosynthesis?
dalvyx [7]

Photosynthesis takes in sunlight and carbon dioxide, along with water and nutrients, so the plant can make energy. That energy is used for cell growth and repair, producing seeds, etc. The plant will exhale oxygen as a byproduct of photosynthesis.

Similarly, cellular respiration is also used to create energy for the host organism. However, the cells take in oxygen along with something like complex sugars (ie the stuff you eat) and use those components to form energy for the cell. The energy for human cells is useful for cell growth and repair, nerve impulses, muscle contractions, etc. Basically anything you can think of that the human body needs to do on a regular basis, it requires energy to do so. A byproduct of cellular respiration is carbon dioxide, which is exhaled out to the environment. The plant will then absorb the CO2 to keep the cycle going.

In short, both processes are used to make energy for the cell. The differences is what the inputs for each process require. Photosynthesis takes in sunlight, water, and carbon dioxide (and other plant nutrients), and exhales oxygen. Cellular respiration takes in oxygen and complex sugars (from plant material or other animals) and exhales carbon dioxide.
