As the basic living part of a plant, the plant cell is involved in many physiological and structural activities. They range from synthesis of proteins and energy to maintaining structural integrity and tautness.

A ribosome consists of two subunits: the large and small subunits. The materials that make up ribosomes are ribonucleic acid, or RNA, and proteins, with approximately 60 percent of a ribosome being made of ribosomal RNA and the other 40 percent consisting of proteins, according to Florida State Univ

According to Nature, viruses do not have ribosomes. Therefore, they cannot form proteins from messenger RNA; this is why viruses must have host cells in order to replicate. Biology 4 Kids indicates that viruses also lack nuclei and mitochondria. Cytoplasm is missing from some viruses, as well.

Ribosomes are like chefs; they take the ingredients and put them together in a complex finished product. Ribosomes are organelles within cells responsible for taking the mRNA and constructing complex polypeptides.

Prokaryotic cells contain ribosomes to handle their protein production. The ribosomes in prokaryotic cells, such as bacteria, are free floating in the cytosol of the cell rather than bound inside a nuclear membrane; this is because prokaryotic cells do not have a nucleus.

In general, plant cells vary from 10 to 100 micrometers, depending what type of plant is being studied. Plant cells are often larger than animal cells, which generally range from 10 to 30 micrometers. Ten micrometers are equivalent to 0.001 centimeters, and 100 micrometers are equivalent to .01 cent

Plant cells work using large amounts of carbohydrates and water with cellular machinery that allows them to process various compounds, particularly inorganic nitrogen compounds, explains Florida State University. Plant cells maintain their structure with the use of a tough cellulose cell wall kept i

The main function of the cell body of a neuron is to integrate synaptic information and transmit this information to other cells via the axon. The cell body also completes a variety of biochemical processes to keep the neuron functioning properly.
