Protists are all organisms that do not have the distinct characteristics of fungi, animals, or plants; mostly single-celled, eukaryotes, many of them have chloroplasts. Protozoa are notable for their ability to move independently, a characteristic found in the majority of species. Quiz: General Characteristics of Protists. The oxygen in today’s atmosphere is almost entirely the result of photosynthetic living, which had its start with the appearance of blue-green algae among the microorganisms” Lewis Thomas, 1984. All algal cells have a definitive cell wall that is thin in some species, but in others, like diatoms, the cell wall is impregnated with silica, which makes it rigid and hard. green algae. Here we have grouped algae with protozoa and slime molds in Protista because mthe majority of algae are unicellular, and even the multicellular algae are structurally simple compared to true plants. An undifferentiated plant body is known as ‘thallus’. Algae Characteristics. General Characteristics of Algae.

Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length. 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 made of glycoproteins. Algae can be multicellular or unicellular. Algae play significant roles as producers in aquatic ecosystems.Microscopic forms live suspended in the water column. D Seventeen patients in ten hospitals had cutaneous infections caused by Rhizopus. All fungi have some features in common, but other special structural and reproductive features separate the four phyla (see Table ).

They are Thallophytes which have chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around the reproductive cells. Viruses & Microscopes . Whereas algae normally grow only in aquatic or extremely moist environments, lichens can potentially be found on almost any surface (especially rocks) or as epiphytes (meaning that they grow on other plants). Algae are usually green, but they can be found in a variety of different colours. Algal cells are primarily eukaryotic cells with membrane-bound photosynthetic (chloroplast), respiratory (mitochondria) and genetic organelles.. The majority of algae live in aquatic habitats (Current Biology, 2014). These organisms are found in the supergroups Chromalveolata (dinoflagellates, diatoms, golden algae, and brown algae) and Archaeplastida (red algae and green algae). Scientists think that red algae likely evolved in deep ocean water. Their photosynthetic pigments are more varied than those of plants, and their cells have features not found among plants … includes multicellular protists (kelp), ranges in size from microscopic to giant kelp, contain pigment fucoxanthin, photosynthetic, silica, fit together- like petri dish, major component of phytoplankton, decomposes and parasites , not photosynthetic, grow as mesh of filaments, important plant pathogen, an important polysaccharide component of brown algal cell walls; used as a stabilizer and emulsifier for some foods and for paint, the broad, expanded part of a leaf; the lamina, a supporting stalk, such as the stalk of a gill fungus or leaf stalk of a fern, (1) basal part of a multicellular alga that attaches it to a solid object; either unicellular or composed of a mass of tissue; (2) cuplike structure at the tips of some tendrils, by means which they become attached, a reproductive cycle in which a haploid (n) phase, the gametophyte, produces gametes, which fuse in pairs to form a zygote, which then germinates to produce a diploid (2n) phase, the sporophyte. Algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.

Name and describe the characteristics of one green algae specimen below. Crash Course! Algae - Algae - Classification of algae: The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960. Spores produced by meiotic division in the sporophyte give rise to new gametophytes, completing the cycle, in plants that have alternation of generations, the haploid (n) , gamete producing generation or phase, the spore producing, diploid (2n) phase in a life cycle characterized by alteration of generations, the diploid (2n) cell resulting from the fusion of male and female gametes, a haploid reproductive cell; gametes fuse in pairs to form zygotes, which are diploid, a reproductive cell, usually unicellular, capable of developing into an adult without fusion with another cell, the two successive nuclear divisions in which the chromosome number is reduced from the diploid (2n) to haploid (n) and segregation of the gene occurs; as a result, gametes or spores are produced, a process during which the duplicated chromosomes divide longitudinally and the daughter chromosome then separate to form two genetically identical daughter nuclei; usually accompanied by cytokinesis, the fusion of two gamete nuclei to form a diploid zygote, a group of water-soluble accessory pigments, including phycocyankns and phycoerythrins, found in red algae and cyanobacteria, close relatives of land plants; all extant charophytes are aquatic (non-marine); sporopollein protects the zygotes, mostly freshwater (some marine and terrestrial); some are unicellular (Clamydomonas); some are colonial (Volvox); and some are unicellular (Ulva). The non-motile cells belong to the kingdom Fungi. 4. Economic importance.
