How is cell size affected, and why?

The cell size is influenced by the cell structure. Eukaryotic cells, owing to their complex intracellular structure and organelles, can actively transport molecules and macromolecules within the cytoplasm. Prokaryotic cells rely on the diffusion for transport through the cytoplasm which limits their size.

What are the beneficial effects of microbes?

- agriculture benefits from nutrient cycling performed by microbes, such as the nitrogen, sulfur, and carbon compounds. In the *nodules* (legumes that live in close association with bacteria) bacteria convert N2 (nitrogen) into NH2 (ammonia) through the process of nitrogen fixation. - Microbes are also associated with our food. They are used to improve food safety and to preserve food. They improve their shelf life and prevents the growth of foodborne pathogens. - Microbes play an important role in all manner of human activities. They are used in the industrial microbiology to make human products, such as pharmaceuticals. They are also used to produce biofuels. They are important for the energy generation, and for environmental clean-up, because they can convert waste materials into ethanol and methane. —> microbes can be used for vaccination and antibiotic therapy. —> microbes can be used for water and wastewater treatment.
