Trochophore A trochophore (/ˈtrɒkɵfɔər/ ; also spelled trocophore) is a type of free-swimming planktonic marine larva with several bands of cilia. By moving their cilia rapidly, a water eddy is created.rochophores exist as a larval form within the trochozoan clade, which include the entoprocts, molluscs, annelids, echiurans, sipunculans and nemerteans. Together, these phyla make up part of the Lophotrochozoa; it is possible that trochophore larvae were present in the life cycle of the group's common ancestor.

- Nostoc is a cyanobacteria that forms large spherical colonies. They are common and can just be seen with the naked eye. Most bacteria are only visible with the strongest lenses of the microscope. An easy way to collect them (and also many small protists) is by placing a cover slip on the surface of pond water.After a night whole colonies of bacteria will grow on the underside of the cover slip.ostoc is a cyanobacteria that forms large spherical colonies.

Chloroplast Helicosporidium is a genus of nonphotosynthetic parasitic green algae that is thought to contain a vestigial chloroplast. Genes from a chloroplast and nuclear genes indicating the presence of a chloroplast have been found in Helicosporidium even if nobody's seen the chloroplast itself.

- A spore is a reproductive cell produced by certain fungi, plants (moss, ferns), and some bacteria. Certain bacteria make spores as a way to defend themselves. Bacterial spores have thick walls. They can resist high temperatures, humidity, and other environmental conditions. The bacteria Clostridia form spores.

Stomata In botany, a stoma (also stomate; plural stomata) is a tiny opening or pore that is used for gas exchange. They are mostly found on the under-surface of plant leaves. In a stoma, there is the chloroplast, a cell wall, a vacuole and a cell nucleus. Air enters the plant through these openings. The carbon dioxide is used in photosynthesis.

Spore In biology, a spore is a unit of asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions. By contrast, gametes are units of sexual reproduction. Spores form part of the life cycles of many plants, algae, fungi and protozoa.Bacterial spores are not part of a sexual cycle but are resistant structures used for survival under unfavourable conditions. Mitospores (or conidia, conidiospores): spores produced by mitosis; they are characteristic of Ascomycetes. 2  Fungi in which only mitospores are found are called mitosporic fungi or anamorphic fungi, and are previously classified under the taxon Deuteromycota (See Teleomorph, anamorph and holomorph).

Difference between auxochrome and chromophore Auxochrome vs chromophore. Auxochrome is a Greek word arising from two word roots; ‘auxo’ meaning “to increase” and ‘chrome’ meaning “color”. Auxochrome is a group of atoms which will impart a particular color when attached to a chromophore but when present alone, will fail to produce that color.

- Spores are specialised cells of the fungus that can function as resting or dispersal propagules. Each spore has the potential to generate another individual of the species. In contrast to seeds, spores have no specialised components that differentiate them from other cells of the thallus.

- A bacterial spore is a spore or spore-like structure produced by bacteria. These include endospores, Akinetes, and spores produced by Actinobacteria and Azotobacter.Spore formation in bacteria is not the principal method of reproduction but simply a method of surviving unfavourable conditions.They have a number of features: 1  They can tolerate extreme dryness. bacterial spore is a spore or spore-like structure produced by bacteria.

Chloroplast Chloroplasts are organelles present in plant cells and some eukaryotic organisms. Chloroplasts are the most important plastids found in plant cells.It is the structure in a green plant cell in which photosynthesis occurs. Chloroplast is one of the three types of plastids.he word chloroplast is derived from the Greek word chloros meaning green and plastes meaning the one who form s. The chloroplasts are cellular organelles of green plants and some eukaryotic organisms. These organelles conduct photosynthesis.

- A truffle is the fruiting body of a subterranean Ascomycete fungus, predominantly one of the many species of the genus Tuber. Truffles are ectomycorrhizal fungi and are therefore usually found in close association with the roots of trees. Spore dispersal is accomplished through fungivores, animals that eat fungi.

- Blastopore. A blastopore is an opening into the archenteron during the embryonic stages of an organism. The distinction between protostomes and deuterostomes is based on the direction in which the mouth (stoma) develops in relation to the blastopore.uring maturation of some animals it evolves into the anus or the mouth; in others it is covered over and contributes to the canal joining the primitive gut with the cavity of the neural tube, the primitive nervous system. blastopore synonyms. blastopore usage examples and blastopore quotes.

Introduction to Fungi Fungi frequently reproduce by the formation of spores. A spore is a survival or dispersal unit, consisting of one or a few cells, that is capable of germinating to produce a new hypha. Unlike plant seeds, fungal spores lack an embryo, but contain food reserves needed for germination.

Tropism Unsourced material may be challenged and removed. (September 2012). Phycomyces, a fungus, exhibiting phototropism. A tropism (from Greek τρόπος, tropos, a turning) is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus.n English, the word tropism is used to indicate an action done without cognitive thought: However, tropism in this sense has a proper, although non-scientific, meaning as an innate tendency, natural inclination, or propensity to act in a certain manner.

Chromatophore Chromatophores in the skin of a squid. Chromatophores are pigment-containing and light-reflecting cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods. Mammals and birds, in contrast, have a class of cells called melanocytes for coloration. Chromatophores are largely responsible for generating skin and eye colour in ectothermic animals and are generated in the neural crest during embryonic development.

- From Wikipedia, the free encyclopedia. A resting spore is a spore created by fungi which is thickly encysted (has a thick cell wall) in order to survive through stressful times, such as drought.It protects the spore from biotic (microbial, fungal viral), as well as abiotic (wind, heat, xeric conditions) factors.June 2011).

- The Chytridiomycota is a phylum of Fungi that reproduces through the production of motile spores (zoospores), typically propelled by a single, poster-iorly directed flagellum. These organisms, often referred to as chytrid fungi or chytrids, have a global distribution with approximately 1000 described spe-cies.
