What structure is required for an organism to be classified as a Photoautotroph?

Only certain organisms called photoautotrophs can perform photosynthesis they require the presence of chlorophyll a specialized pigment that absorbs certain portions of the visible spectrum and can capture energy from sunlight.

What structure is required for an organism to be classified as a Photoautotroph quizlet?

The protons are generated during oxidation reactions. The membrane is permeable to protons. The chloroplasts house the structures required for photoautotrophs like plants to undergo photosynthesis namely the stroma and the thylakoids.

What structure is responsible for absorbing solar energy during light reactions?

The electromagnetic energy of sunlight is converted to chemical energy in the chlorophyll-containing cells of photosynthetic organisms. In eukaryotic cells these reactions occur in the organelle known as the chloroplast. In the chloroplast chlorophyll is the pigment that absorbs the sunlight.

What organisms are capable of photosynthesis?

Most plants algae and cyanobacteria perform photosynthesis such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth’s atmosphere and supplies most of the energy necessary for life on Earth.

What organism category is capable of photosynthesis quizlet?

Autotrophs– include plants algae and cyanobacteria and are photosynthetic organisms.

What’s the difference between Phototrophs and Chemotrophs?

The difference between Phototrophs and Chemotrophs is Phototrophs consume sunlight as the source of energy to undergo photosynthesis but Chemotrophs use chemical reactions and undergo chemosynthesis to get energy. Chemotrophs do not use sunlight to undergo chemosynthesis.

How does a photosystem capture solar energy?

Explain how photosystems capture solar energy. Pigments found in the light-harvesting complexes of the photosystems attract protons and absorb them. The pigments then pass the energy from molecule to molecule until it reaches the reaction center.

Is to chloroplasts as cellular respiration is to?

Photosynthesis is to chloroplasts as cellular respiration is to mitochondria.

What types of organisms carry out respiration?

Organisms from all kingdoms of life including bacteria archaea plants protists animals and fungi can use cellular respiration.

What energy is needed by organism during cell respiration?

Adenosine Triphosphate(ATP) energy is needed by organisms during cell respiration.

What is chloroplast structure?

Structure of Chloroplasts

Chloroplasts are oval-shaped and have two membranes: an outer membrane and an inner membrane. Between the outer and inner membrane is the intermembrane space approximately 10-20 nm wide. The space within the inner membrane is the stroma the dense fluid within the chloroplast.

What energy is needed by organisms in cellular respiration?

All organisms respire in order to release energy to fuel their living processes. The respiration can be aerobic which uses glucose and oxygen or anaerobic which uses only glucose. Because this process occurs in all life we call it a universal chemical process.

What organism have eukaryotic cells with the ability to do photosynthesis?

Explanation: Photosynthetic eukaryotes: Eukaryotes like plants and green algae contain membrane bounded organelles which aid them to perform photosynthesis. The process of photosynthesis is basically divided into two steps i.e Light reactions and dark reactions (known as Calvin cycle or C3 pathway).

Do Autotrophs perform photosynthesis?

Most autotrophs use a process called photosynthesis to make their food. In photosynthesis autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. … Algae phytoplankton and some bacteria also perform photosynthesis.

are photosynthetic organisms always eukaryotes? no! … do photosynthetic organisms require chloroplasts?

Which molecules are produced by autotrophs during photosynthesis?

Which molecules are produced by autotrophs during photosynthesis? carbon dioxide water and energy.

What are the main types of photosynthetic autotrophs?

There are two types of autotrophs: photoautotrophs and chemoautotrophs. Photoautotrophs get their energy from sunlight and convert it into usable energy (sugar). This process is called photosynthesis.

What do organisms carry out photosynthesis?

This process is called photosynthesis and is performed by all plants algae and even some microorganisms. To perform photosynthesis plants need three things: carbon dioxide water and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves flowers branches stems and roots.

How are autotrophs different from heterotrophs?

A major difference between autotrophs and heterotrophs is that the former are able to make their own food by photosynthesis whereas the latter cannot. … Autotrophs are able to manufacture energy from the sun but heterotrophs must rely on other organisms for energy.

What is the difference between photoautotrophs and autotrophs?

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.

Are Chemotrophs photosynthetic?

1) Chemoautotrophs: They are able to make their own food through chemosynthesis. They derive energy from chemical reactions and synthesize the required organic compounds from carbon dioxide.

Phototrophs Chemotrophs
They generally perform photosynthesis. They generally perform chemosynthesis.

In what plant structures does photosynthesis occur Make your description as specific as you can?

Photosynthesis occurs in the chloroplast an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast.

What cell structures and pigments are involved in photosynthesis?

In plants photosynthesis takes place in chloroplasts which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane called the thylakoid membrane that forms long folds within the organelle.

What cell structures are most important to photosynthesis Why?

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells including the synthesis of fatty acids membrane lipids …

Where are electron carriers found in eukaryotic cells?


In Eukaryotes it occurs in inner membrane of mitochondria while in prokaryotes it occurs in cell plasma membrane.

What is the photosynthesis of energy requirement?

The minimum quantum requirement for photosynthesis under optimal conditions is about nine. Thus the energy used is 9 × 50 or 450 kcal per mole of oxygen evolved. … Third rates of photosynthesis in bright sunlight sometimes exceed the needs of the plants resulting in the formation of excess sugars and starch.

Which characteristic is shared by all prokaryotes and eukaryotes?

What characteristic is shared by all prokaryotes and eukaryotes? The ability to store hereditary information. All cells reproduce. Living organisms can be classified as prokaryotes or eukaryotes.

Do autotrophs need to carry out cellular respiration?

Yes autotrophs need to carry out cellular respiration.

Why do autotrophs undergo cellular respiration?

Autotrophs make their own food. … Many autotrophs make food through the process of photosynthesis in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose release its energy and make ATP.

Do autotrophs perform cellular respiration?

Cellular respiration occurs in the cells of all living things. It takes place in the cells of both autotrophs and heterotrophs. All of them burn glucose to form ATP.

What are materials needed during cell respiration?

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP waste products include carbon dioxide and water.

Why do organisms need to respire?

All living organisms respire. Cells need and use the energy that is formed through this process to assist with life processes in order for organisms to survive and reproduce. Oxygen and carbon dioxide are the main gases involved in aerobic respiration. … They carry out gas exchange in a different way to mammals.

Is cellular respiration needed by all organisms?

Explanation: All living organisms need energy for performing several activities of body. Energy is stored in food and to release energy cellular respiration is required.
