What Type Of Organism Does Photosynthesis Occur In? …

So we can summarize by saying that the photosynthetic plantstrap solar energy to form ATP and NADPH (Light Phase) and thenuse these as the energy source to make carbohydrates and otherbiomolecules from carbon dioxide and water (Dark Phase),simultaneously releasing oxygen in to the atmosphere. Thechemoheterotrophic animals reverse this process by using theoxygen to degrade the energy-rich organic products ofphotosynthesis to CO2 and water in order to generate ATP fortheir own synthesis of biomolecules.

Organisms That Use Photosynthesis by Steff Newkirk …

Only plants can do photosynthesis.Photosynthesis is the process of harnessingenergy from sunlight to generate chemical energy,which can be stored and used later. Thisstored chemical energy comes from the conversionof inorganic carbon (carbon dioxide) into organiccarbon, or food. Every living thing needs a sourceof stored energy for survival, even plants! Thinkof the stored energy as a battery, which isproviding energy not just for muscle movement(which plants obviously don't worry about), butfor all of the essential processes of life (cellgrowth and repair, for example). Living thingsthat can not harness and store energy themselvesthrough photosynthesis (and this includes humans,animals, insects, bacteria, viruses) HAVE to usethe energy harnessed and stored by plants tosurvive, or their battery runs out. Only plantshave the ability to recharge the batteries, soliving organisms are dependent on plants. Theprocess that releases the energy stored in thesebatteries is called the Krebs cycle.

The process inphotosynthetic protists and cyanophytes resembles that in greenplants; it differs in the photosynthetic bacteria in that compoundsother than water serve as a reactant and oxygen is not produced.

Photoaututrophs utilize sunlight for energy and CO2 for theircarbon source by this process of PHOTOSYNTHESIS whereby sunlightis absorbed by a complex compound known as chlorophyll andconverted to energy which drives a series of chemical reactionsthat ultimately removes hydrogen from water or other compoundsand then combines the hydrogen with carbon dioxide in a way thatproduces sugars.

What living organisms are responsible for photosynthesis

Photosynthetic organisms can be divided into two classes:those which produce oxygen and those which do not. Photosyntheticbacteria do not produce oxygen (in fact some of them calledanaerobes cannot tolerate oxygen) and this is considered a moreprimitive type of photosynthesis (in which the hydrogen donor ishydrogen sulfide, lactate or other compounds, but not water).Plants and one type of bacteria (cyanobacteria) do produceoxygen, an evolutionarily more advanced type of photosynthesis(in which the hydrogen donor is water).

Organisms that carry-out photosynthesis are like oxygen factories

The fact of the matter is, plants areincredibly special because only plants can dophotosynthesis. For this reason, every organism onearth ultimately relies on plants for its survival(with a few exceptions, which I'll discuss later).Even animals that eat only meat, hunting andcatching their food as prey, ultimately rely onplants for survival because the prey are eatingplants, or are eating insects that are eatingplants, or are eating animals that are eatinganimals that are eating plants, etc.

What were the 1st organisms to do photosynthesis

Without photosynthesis, not only would replenishment of thefundamental food supply halt but the Earth would eventually becomedevoid of oxygen.Just as the organic molecules in the bodies of living organismscontain energy converted by photosynthesis from the energy of theSun, so do the molecules of fossil fuels.

What type of organisms can photosynthesize?

All phytoplankton photosynthesize, but some get additional energy by consuming other organisms. Phytoplankton growth depends on the availability of carbon dioxide, sunlight, and nutrients.
