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. [1]
Actinastrum consists of eight (sometimes two, four or 16) cells, which are attached together at a common point to form a star-shaped colony, termed a coenobium. The colonies are often aggregated to form compound coenobia. Cells are 7–40 μm long and 1–8 μ wide, much longer than broad, and are cylindrical, cigar-shaped, or pointed.
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
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 An arranged colony of algae that acts like a single organism. coenocyte A single cell with multiple nuclei, formed when nuclear division was not followed by cytokinesis. coleoptile One type of sheath in the structure of monocotyledon ous seeds.

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.

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]
