Isoetes Isoetes, commonly known as the quillworts, is a genus of plants in the class Isoetopsida and order Isoetales.They are lycopods. There are about 140–150 species, with a cosmopolitan distribution but often scarce to rare.ompared to other genera, the genus Isoetes is a technically difficult and relatively poorly known. Even after various studies with cytology, scanning electron microscopy, and chromatography, the individual species are still difficult to identify and their phylogeny is still disputed.

- Image courtesy: BioMEDIA ASSOCIATES The paramecium, genus of protozoa of the phylum Ciliophora, is often called slipper animalcules because of their slipper-like shape. Paramecia are unicellular organisms usually less than 0.25 mm (0.01 in) in length and covered with minute hair-like projections called cilia. paramecium is a small one celled (unicellular) living organism that can move, digest food, and reproduce. They belong to the kingdom of Protista, which is a group (family) of similar living micro-organisms.

Clubmosses: An Ancient and Interesting Group of âFern Alliesâ Fern allies include the horsetails, clubmosses, spikemosses, and quillworts. The common name “clubmoss” is based on the premise that at first glance these plants resemble mosses (mosses are bryophytes and thus, non-vascular plants), and because they often have club-like structures that produce spores. Clubmosses are all perennial evergreen plants with numerous small leaves.

What are Zooxanthellae? Zooxanthellae are single-celled plants that live in the tissues of animals. They are dinoflagellates, a group of microscopic plants which are usually found swimming and floating in the sea.Organisms which live like this are called plankton, and those that are plants are called phytoplankton.n tropical waters almost all coral animals contain a colony of zooxanthellae. Without these symbiotic plants, the coral animals would be unable to obtain enough nutrients to build their calcium carbonate skeletons, which accumulate to form the vast coral reefs of the tropics.

Chisternon Hemichordata, which includes the acorn worms, has been presented as a fourth chordate subphylum, but it now is usually treated as a separate phylum. The Hemichordata, along with the Echinodermata (which includes starfish, sea urchins, sea cucumbers, and crinoids), form the Ambulacraria, the sister taxon of the Chordates.

Wildlife The phylum Echinodermata, which contains about 6000 species, gets its name from the Greek, literally meaning “spiny skin.” This phylum exists exclusively in the sea and includes sea stars, urchins, brittle stars, and sea cucumbers. They are simple animals, lacking a brain and complex sensing organs.

Woodlouse They form the suborder Oniscidea within the order Isopoda, with over 3,000 known species. Woodlice in the genus Armadillidium can roll up into an almost perfect sphere as a defensive mechanism, hence some of the common names such as pill bug.Most woodlice, however, are not able to do this.ome species of woodlice are able to roll into a ball-like form when threatened by predators, leaving only their armoured back exposed. This ability, or dominant behaviour, explains many of the woodlouse's common names.

Woodlouse Pillbugs (woodlice of the family Armadillidiidae, also known as pill woodlice) can be confused with pill millipedes of the order Glomerida. Both of these groups of terrestrial segmented arthropods are about the same size. They live in very similar habitats, and they can both roll up into a ball.

More About Ferns (monilophytes) Some past authorities had lumped them in with other non-seed bearing vascular plants such as lycopsids (club mosses, spike mosses and quillworts), sphenophytes (horsetails) and psilophytes (whisk ferns); the common phrase ferns and fern allies is a legacy of this classification scheme.

- Biological factors that are thought to shape gender differences include hormones and lateralization of brain function. Hormones may organize a biological predisposition to be masculine or feminine during the prenatal period, and the increase in hormones during puberty may activate that predisposition.
