what are auxotrophs and prototrophs?
239740
An auxotroph is an organism that displays this characteristic; auxotrophic is the corresponding adjective. ... Prototrophic cells (also referred to as the 'Wild Type') are self sufficient producers of required amino acids, while auxotrophs require to be on medium with the amino acid that they cannot produce .

Most phototrophs are the autotrophs that perform photosynthesis, which are also known as photoautotrophs. These organisms have the ability to fix carbon from carbon dioxide into organic compounds, such as glucose. Chemotrophs, on the other hand, do not get their energy from carbon.

Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.

Archaebacteria are classified as autotrophs. They make their food from the basic materials in their environment like carbon, oxygen, hydrogen, metals and simple organic molecules such as sugar.

Mollusks, annelids, and arthropods are protostomes. Echinoderms and chordates are deuterostomes. This distinction is important.

Autotrophs and Heterotrophs Other types of bacteria make their own food by converting light energy, chemical energy or inorganic substances into usable energy that these single-celled organisms need to live. These do-it-yourself bacteria are autotrophs, like plants and algae.

There are some unicellular organisms that carry out both heterotrophic and autotrophic nutrition, meaning they are mixotrophic. Such is the case of euglena gracilis (below), which carries out photosynthesis in its chloroplasts as well as also feeding on detritus or smaller organisms by endocytosis.

Autotroph vs. ... Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.

Chemoautotrophs include prokaryotes that break down hydrogen sulfide (H2S the “rotten egg” smelling gas), and ammonia (NH4).

Chemotrophs are a class of organisms that obtain their energy through the oxidation of inorganic molecules, such as iron and magnesium. The most common type of chemotrophic organisms are prokaryotic and include both bacteria and fungi.

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. Chromophore is that part of the molecule which when exposed to visible light will absorb and reflect a certain color.

autotrophs make their own food-plants & algae. heterotrophs obtains energy from food it consumes.

Phylum Arthropoda are organisms which have jointed appendages and include: Crustaceans, Insects, Spiders to name a few. They are invertebrates. They are protostomes. This refers to an animal whose mouth is formed from the blastopore during embryonic development.

A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Protists that can be autotrophic, heterotrophic or both are called mixotrophs.

An autotroph is an organism able to make its own food. Photoautotrophs are organisms that carry out photosynthesis. Using energy from sunlight, carbon dioxide and water are converted into organic materials to be used in cellular functions such as biosynthesis and respiration.
