Most phytoplankton, especially flagellate plant plankton, like dinoflaggelates, are possibly capable of using both sexual and non-sexual reproduction, but most use mitosis-asexual most the time. Depends on species, env factors, water conditions.

The term you are looking for is "autotrophs."  The word means "self-feeders" and these types of organisms can synthesize their own energy-rich organic molecules.  They do not require any organic molecules from outside sources; only inorganic molecules.\nAutotrophs include plants and other photosynthetic organisms, and chemosynthetic bacteria (who form their food from chemicals).  \nAs a side note, heterotrophs are the organisms that cannot create their own food.\n\nHope this is helpful :-)

Chemosynthetic bacteria, chemosynthetic bacteria can survive without light energy, they can live in dark and inhospitable regions, including the hydrothermal vents of the Pacific Ocean. Around these vents, where temperatures reach up to 350°C/662°F, the chemosynthetic bacteria are the basis of a food web supporting fishes and other marine life including the fairy shrimp

Theory? I mean, I can think of the endosymbiotic theory, but that's eukaryotes. Perhaps you mean the organelle that carries out photosynthesis in prokaryotes?

Trees are phototrophs, they produce their own food by using carbon dioxide, water, and sunlight.

The plant kingdom, one of four eukaryotic kingdoms, is composed of multicellular, autotrophic organisms that photosynthesize to fix inorganic carbon (from atmospheric CO2) into organic molecules. Plants are the foundation of all terrestrial habitats, and serve as terrestrial Earth’s primary autotrophs, making organic molecules that will cycle through the food webs of most ecosystems. The photosynthetic capabilities of plants ultimately allow all terrestrial members of the animal kingdom to survive.\n\nOne hallmark of plant cells is the cell wall, which, in contrast to cell walls of single-celled organisms, is made of cellulose. The cell walls provide support for plant cells, as well as support and cohesiveness for plant tissue. Unlike the plasma membrane, the cell wall is not a semipermeable membrane, and so the shared cell walls between adjoining plant cells must have openings, plasmodesmata, to allow material transport and communication. Another distinguishing feature of plant cells is the large central vacuole, which stores a water reserve as well as essential chemicals, waste products of cellular metabolism, and sometimes other species-specific functions, such as storage of poisons or flower pigments. The central vacuole can also aid in cell growth by absorbing water.\n\nExcluding a few photosynthetic protists and cyanobacteria, plant cells are the only cells that contain chloroplasts. These organelles carry out the processes of photosynthesis, converting light energy into chemical energy and storing it as sugar. As well as producing food for ecosystems, photosynthesis releases oxygen molecules as byproducts, which replenish atmospheric oxygen used in cellular respiration and form a layer of ozone, O3, which shields the earth from solar ultraviolet rays.\n\nPlants probably evolved from multicellular green algae called charophytes and were the first multicellular organisms to colonize land. In order to do this, plants had to evolve several new characteristics in the form of distinct, specialized organs, which protists and algae lack. First of all, plants need to have a form of anchorage in the ground and rigid stem tissue for support. Thus, plants have developed root structures, which, in addition to anchoring a plant in the ground, allow the plant to take up chemical nutrients from the soil. Cellulose-containing cell walls developed in plant cells to maintain a form of rigidity in the part of the plant above ground. These account for the stiffness of plant stems and from the hardness of wood. Marine algae, which are suspended in water and can absorb nutrients from all around, have neither of these structures. Also, to prevent water loss in a terrestrial environment, plants evolved a waxy cuticle, which covers stem and leaf surfaces. Gases for photosynthesis can not diffuse across this cuticle, so tiny pores called stomata are present in the cuticle.\n\nBecause plants have organs that serve different functions, they must have systems to distribute necessary substances throughout the plant. Sugars, produced in photosynthesis, must be distributed to the body and roots of the plant that do not photosynthesize. Water and nutrients from the soil, taken up by the roots, must also make their way into the plant body and leaves. To perform these essential functions, plants contain a vascular tissue network, which consists small tubes running throughout the plant. There are two types of vascular tissue: xylem, which are small tubes dead cells that transport water and minerals up from the roots, and phloem, which are living cells that distribute sugars produced in photosynthesis.\n\nAlso characteristic of plants, as well as some algae, are gametangia that protect gametes. These are pockets of cells that protect the egg cell, and where the egg is fertilized.\n\nPlants have a life cycle unlike that of any animal, fungus, or bacteria. Probably a trait inherited from protistan (algal) ancestors, diploid and haploid generations alternate

Oh good greif.\n\nThe correct answer is plantae.\n\nActually the correct answer is protista, since there are far more multicelluar algae than there are plants. But of the options gives plantae is the 'most correct'.\n\nAnimals and fungi do not photsynthesise, ever. They are defined by being obligate heterotrophs. \n\nEubacteria can photosynthesise but they are prokaryatotesand by defintion lack a nucleus.\n\nThat leaves plantae as the only group that is nucleated and capable of photosynthesis.

Cyanobacteria have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.\n\nMany Proterozoic oil deposits are attributed to the activity of cyanobacteria.The cyanobacteria have also been tremendously important in shaping the course of evolution and ecological change throughout earth's history. The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras. Before that time, the atmosphere had a very different chemistry, unsuitable for life as we know it today.\n\nThe other great contribution of the cyanobacteria is the origin of plants. The chloroplast with which plants make food for themselves is actually a cyanobacterium living within the plant's cells. Sometime in the late Proterozoic, or in the early Cambrian, cyanobacteria began to take up residence within certain eukaryote cells, making food for the eukaryote host in return for a home. This event is known as endosymbiosis, and is also the origin of the eukaryotic mitochondrion.\n\nSo, to put it in a nutshell, they are the oldest, they created the oxygen atmosphere and they allowed plants to feed themselves.  Amazing for such a small little thing.

I dont know about its niche, but you could extrapolate from the following:\nDeinococcus has the remarkable ability to repair its genome from fragments. Scientists have completely fractured the genome, and in most organisms, this would kill the cell. However deinococcus can put its genome back together in the right order. weird isn't it. It can also grow at radiation high enough to melt glass. Its a crazy little bugger isn't it.
