Viruses are considered non-living organisms for a variety of reasons. One of the main reasons is that viruses are incapable of creating their own proteins and must hijack host cell ribosomes in order to make them.

Virus structures contain both proteins and nucleic acids, but are unable to replicate their genetic material unless they infect a host cell.

Fungal cell walls can be differentiated from plant and bacterial cell walls in that they are made of the polysaccharide chitin. Plant cell walls use cellulose, and bacteria use peptidoglycan. Amylose is a component of starch.

The plant is only able to use absorbed light during photosynthesis; reflected light cannot be used as energy, as it is simply returned back into the surroundings. Red light will make a plant grow the fastest because it is absorbed. Since green light is reflected, growing a plant in green light will result in very slow growth. The light will effectively bounce off the plant, rather than being absorbed.

Bacteria are prokaryotic organisms and are considered alive. Bacteria can survive and reproduce independent of a host (consider a colony of bacteria cells growing in a Petri dish). Though they do not have membrane-bound organelles, like a nucleus or mitochondria, bacterial cells do have DNA and are still able to produce cellular energy.

This question confuses many properties of viruses with those of bacteria. Viruses are not generally considered alive and require a host cell in order to replicate.
