WebVolvox is a polyphyletic genus in the volvocine green algae clade. 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 … WebMar 7, 2024 · Some flagellates are free-living, such as Chlamydomonas. Some are parasitic, such as Trichomonas. Some live singly, such as Euglena. Some live in colonies, such as Synura. Euglena belongs to a group of protists that move about with the help of one or more thread-like flagella, commonly referred to as flagellates.

WebDec 24, 2024 · A homologous trait is often called a homolog (also spelled homologue). In genetics, the term “homolog” is used both to refer to a homologous protein and to the gene ( DNA sequence) encoding it. As with anatomical structures, homology between protein or DNA sequences is defined in terms of shared ancestry. Two segments of DNA can have … WebThe most abundant group of algae is the green algae. The green algae exhibit similar features to the land plants, particularly in terms of chloroplast structure. That this group of protists shared a relatively recent common ancestor with land plants is well supported. The green algae are subdivided into the chlorophytes and the charophytes. five heart farms texico nm
