Coenocyte of Sphaeroforma arctica Botrydium, showing a coenocytic body. A coenocyte (/ ˈ s iː n ə ˌ s aɪ t /) is a multinucleate cell which can result from multiple nuclear divisions without their accompanying cytokinesis, in contrast to a syncytium, which results from cellular aggregation followed by dissolution of the cell membranes inside the mass.

Pediastrum is a genus of green algae, in the family Hydrodictyaceae. [1] It is a photoautotrophic, nonmotile coenobial green alga that inhabits freshwater environments. The name Pediastrum comes from the Greek root words pedion, meaning "plane", and astron, meaning "star", referring to its overall shape.
Coenobium or coenobia may refer to : Cenobitic monasticism (cenobium, cenobite), a monastic community in a tradition stressing communal life, as opposite to eremitism Coenobium (morphology) , a colony of cells, notably in algae
Coelastrum is a genus of green algae in the Scenedesmaceae family. It is a common component of the phytoplankton in freshwater habitats such as ponds, lakes, waterfalls, and temporary pools of water, [1] particularly eutrophic ones. [2]

Each mature Volvox colony is composed of up to thousands of cells from two differentiated cell types: numerous flagellate somatic cells and a smaller number of germ cells lacking in soma that are embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix [1] made of glycoproteins. [3]
One equation used to analyze biological exponential growth uses the birth and death rates in a population. If, in a hypothetical population of size N, the birth rates (per capita) are represented as b and death rates (per capita) as d, then the increase or decrease in N during a time period t will be = ()
Selection coefficient, usually denoted by the letter s, is a measure used in population genetics to quantify the relative fitness of a genotype compared to other genotypes. . Selection coefficients are central to the quantitative description of evolution, since fitness differences determine the change in genotype frequencies attributable to selecti
