Cell types include viruses, prokaryotes, and eukaryotes. |
|
These are sub-cellular organisms, consisting principally of nucleic acids and proteins. They are not capable of independent living, but depend on the reproductive machinery of living cells.
Subtypes are not yet included. (Before nucleus) Genetic material is in the form of a circular loop called a plasmid, in a nuclear region, but lack a membrane-bound nucleus. Posess ribosomes. Have storage granules. Lack membrane-bound organelles. Posess an outer plasma membrane.
May have pili (allowing connection to other cells and exchange of genetic material). May have flagella.
May have a periplasmic space. Usually have a cell wall. May have an outer membrane. May have a capsule.
There are many different types of these, corresponding to different types in eukaryotic organisms. (True nucleus) These have a Genetic material is found in chromosomes inside a membrane-bound nucleus. Posess cytosol (including ribosomes), a cytoskeleton, membrane bound organelles [mitochondria, chloroplasts, smooth endoplasmic reticulum, rough endoplasmic reticulum, golgi apparatus, vesicles, lysosymes, vacuoles, peroxisomes] posess an outer plasma membrane, cytocalyx (external material), [cell walls]

This is connected first to other sciences. Physics, chemistry, astronomy, earth science, and other areas of biology may be conneted. |

Other areas of knowledge such as Personal studies, anthropology, culture, institutions, sociology, and history will be connected as this site develops. |
