Plants Are Photosynthetic Autotrophs. What Does This Mean??

Plants Are Photosynthetic Autotrophs. What Does This Mean??

Plants are photosynthetic autotrophs which means that they are able to produce their own food and do it through the process of photosynthesis.

What does it mean that plants are photosynthetic autotrophs?

Plants are autotrophs which means they produce their own food. They use the process of photosynthesis to transform water sunlight and carbon dioxide into oxygen and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Which of the following are photosynthetic autotrophs?

Which of the following are photosynthetic autotrophs? Algae plants all bacteria some bacteria arthropods protists.

Which of the following is a good reason for using fast growing trees as fuel quizlet?

Which of the following is a good reason for using fast-growing trees as fuel? Vigorously growing plants remove a lot of carbon dioxide from the air.

Where does the energy for the Calvin cycle come from?

The energy used in the Calvin cycle comes from the ATP and NADPH that are made in the Light Reactions stage of photosynthesis.

What are auto autotrophs?

Autotrophs are organisms that can produce their own food using materials from inorganic sources. The word “autotroph” comes from the root words “auto” for “self” and “troph” for “food.” An autotroph is an organism that feeds itself without the assistance of any other organisms.

What are photosynthetic autotrophs and chemosynthetic autotrophs?

Photosynthetic autotrophs synthesize organic compounds. Chemosynthetic autotrophic bacteria make use of chemical to prepare their food. These bacteria obtain energy from inorganic compounds.

Which of the following is photosynthetic?

Explanation: Carbon dioxide water and light are all needed for photosynthesis to take place. Chlorophyll is a green photosynthetic pigment found in plants algae and cyanobacteria. Chlorophyll is vital for photosynthesis it allows plants to absorb energy from light.

Which of these protists is photosynthetic autotrophic?


The plant-like protists or algae are all photosynthetic autotrophs.

Which of the following organisms are photosynthetic?

Plants algae and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1).

What information is presented on the Y axis of the graph?

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).

Which of the following equation represents photosynthesis?

The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2.

What is one reason why plants have accessory pigments?

Accessory pigments help plants absorb additional light. Plants need to make these accessory pigments to maximize the amount of photosynthesis they can do. More pigments = More glucose or food for the plant!

Where does the oxygen that is released come from in photosynthesis?


The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.

What are 3 factors that affect the rate of photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity carbon dioxide concentration and temperature.
  • Light intensity. Without enough light a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide. …
  • Carbon dioxide concentration. …
  • Temperature.

Why is bioethanol often added to gasoline?

Why is bioethanol often added to gasoline? … It costs less than gasoline. Ethanol is a renewable resource that can increase fuel efficiency and lower vehicle emissions.

Why are photosynthetic autotrophs important to the ecosystem?

Photosynthetic autotrophs are important to an ecosystem because they produce food for the heterotrophs. Autotrophs are able to make their own food…

Are plants Chemotrophs?

Chemoautotrophs are cells that create their own energy and biological materials from inorganic chemicals. … Photoautotrophs use energy from sunlight to make their biological materials. These include green plants and photosynthesizing algae.

Why are plants autotrophs?

Green plants are called autotrophs since they are able to synthesize their own food. In photosynthesis solar energy is captured by the pigment Chlorophyll. During photosynthesis plants consume carbon dioxide and release oxygen gas.

What do photosynthetic mean?

Definition of photosynthesis

: synthesis of chemical compounds with the aid of radiant energy and especially light especially : formation of carbohydrates from carbon dioxide and a source of hydrogen (such as water) in the chlorophyll-containing cells (as of green plants) exposed to light.

What are photosynthetic microbes?

Essentially photosynthetic bacteria are prokaryotes that are capable of converting light energy (from the sun) into chemical energy through a process known as photosynthesis. They are also classified as photoautotrophs because they can make their own energy using inorganic material from their surroundings.

Why are cyanobacteria called photosynthetic autotrophs?

“Asseration : Cyanobacteria are photosynthetic autotrophs. Reason : Cyanobacteria have chlorophyll a and b similar to green plants.” … Cyanobacteria (also referred to as blue-green alagae) are photosynthetic autotrophs. They have chlorophyll a similar to green plants.

What is the function of the photosynthetic pigments in photosynthesis?

Photosynthetic pigments are the molecules responsible for absorbing electromagnetic radiation transferring the energy of the absorbed photons to the reaction center and for photochemical conversion in the photosynthetic systems of organisms capable of photosynthesis.

Which of the following is a photosynthetic bacteria?


So the correct answer is ‘Cyanobacteria‘.

Where can photosynthetic bacteria be found?

Photosynthetic bacteria are prokaryotes that are capable of carrying out photosynthesis. They are widely distributed occupying several habitats like soil lakes paddy fields oceans rivers and activated sludge (Koblížek et al. 2006 Okubo et al. 2006).

What is an autotrophic protozoan?

An autotrophic protist is a type of single-celled organism that can create its own food. The best-known group is the algae.

What characteristic of a plant indicates that it is autotrophic?

Most plants are autotrophs organisms that synthesize all their own organic nutrients and do not rely on other organisms for food. The reason that plants are autotrophic is that they carry out photosynthesis in their leaves.

Are all protists photosynthetic?

Some protists are capable of photosynthesis some live in mutualistic relationships with other protists some are single celled some are multicellular or form colonies some are microscopic some are enormous (giant kelp) some are bioluminescent and some are responsible for a number of diseases that occur in plants …

How important are photosynthetic organisms?

Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis the carbon cycle could not occur oxygen-requiring life would not survive and plants would die. … Without photosynthesis there would be little to no oxygen on the planet.

How do you know if something is photosynthetic?

How can we tell if they are performing photosynthesis? One way is to see if they are giving off oxygen the most important byproduct of photosynthesis. Of course we can’t usually see leaves producing oxygen but watch what happens when you use an underwater plant!
