The chloroplast contains three main pigments that absorb light energy chlorophyll a chlorophyll b and carotenoids. Chlorophyll is most abundant in the thylakoids. … In eukaryotes it occurs in the thylakoid membrane of the chloroplast. In eukaryotes the dark reaction happens in the stroma of the chloroplast.

What organelle performs photosynthesis in plants?


In plants and algae which developed much later photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis NADPH and ATP are used by the photosynthetic cells to produce many organic molecules.

In which part of a chloroplast does photosynthesis occur quizlet?

They produce the source of chemical energy for themselves and for other organisms. In what two parts in a chloroplast does photosynthesis take place? The Grana and The Stroma.

What is the site of photosynthesis Class 7?

Chloroplast is the site of photosynthesis. At the end of photosynthesis carbohydrate and oxygen are formed. Carbohydrate is used as food and oxygen is emitted out to the atmosphere. This whole process of making food by plants is called photosynthesis.

Is a site of photosynthesis *?

chloroplast structure within the cells of plants and green algae that is the site of photosynthesis the process by which light energy is converted to chemical energy resulting in the production of oxygen and energy-rich organic compounds.

What is the site of photosynthesis Class 10?

What is a specialized organelle?

Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs such as the heart liver stomach and kidneys serve specific functions to keep an organism alive organelles serve specific functions to keep a cell alive.

What is the organelle called where this occurs?

Photosynthesis occurs within the organelle called the chloroplast. Photosynthesis happens in the plant kingdom called for example a sun flower uses the process of photosynthesis to make food for itself.

Which end is the flagellum located?


The flagellum is located on the anterior (front) end and twirls in such a way as to pull the cell through the water.

In what part of the chloroplast does photosynthesis occur in?

Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).

Which organelle contains chlorophyll and is the location for photosynthesis quizlet?

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll.

What two parts of the chloroplast does photosynthesis occur?

Photosynthesis occurs in granum and stroma parts of chloroplast.

What is meant by site of photosynthesis?

Answer: leaves prepare their food in the presence of sunlight and a green coloured substance present in them they also use water and carbon dioxide. this process is called photosynthesis. the site of photosynthesis in plants : mesophyll of the leaves inside the chloroplasts.

What is a parasite class 7?

Parasites are organisms that depend upon another organism (host) for food and cause harmful effects or dieseases to the host. Examples: Cuscuta (Amarbel) mosquitoes and head lice. saprotrophs are orgnisms that obtain nutrition from dead and decaying organic matter. Examples: Fungi and some bacteria.

Where is the specific location of photosynthesis?

In plants the process of photosynthesis takes place in the mesophyll of the leaves inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids which contain the pigment chlorophyll.

Which organelle is the site of respiration?


Encyclopædia Britannica Inc. The “powerhouses” of the cell mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).

Which molecule is present in chlorophyll?

Chlorophyll a contains a magnesium ion encased in a large ring structure known as a chlorin. The chlorin ring is a heterocyclic compound derived from pyrrole. Four nitrogen atoms from the chlorin surround and bind the magnesium atom. The magnesium center uniquely defines the structure as a chlorophyll molecule.

What are the sites of photosynthesis Class 9?

Sites of photosynthesis
  • Leaves are considered to be the sites of photosynthesis. Hence they are called as food factories of the plant.
  • Leaves possess small pores called as stomata on both their surfaces. Stomata are the structures which help in the exchange of gases. …
  • Leaves are rich in plastids.

What is the site of light reaction in chloroplast?

thylakoid discs
The light reaction takes place in the thylakoid discs. There water (H20) is oxidized and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.Aug 21 2014

Where is chlorophyll present?

Chlorophyll is located in a plant’s chloroplasts which are tiny structures in a plant’s cells.Sep 13 2019

What does the Golgi apparatus do?

A Golgi body also known as a Golgi apparatus is a cell organelle that helps process and package proteins and lipid molecules especially proteins destined to be exported from the cell. Named after its discoverer Camillo Golgi the Golgi body appears as a series of stacked membranes.

Is the nucleus an organelle?

​Nucleus. A nucleus is a membrane-bound organelle that contains the cell’s chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.

Is chloroplast an organelle?

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. … Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.

Where does photosynthesis occur in the biosphere?

Photosynthesis occurs in the cells of plants bacteria and protists in the biosphere and geosphere.

Does photosynthesis occur in the mitochondria?

Photosynthesis occurs in the chloroplasts whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen which are then used as the starting products for cellular respiration.

Which of these occur in photosynthesis?

During true photosynthesis the carbon dioxide is reduced and water is oxidized. The carbon dioxide is reduced to glucose and the water is oxidized to release oxygen in the presence of sunlight to synthesize nutrients such as carbohydrates in the form of glucose and release oxygen.

Is the paramecium a unicellular or multicellular?

Paramecium are unicellular protozoans classified in the phylum Ciliophora (pronounced sill-ee-uh-FORE-uh) and the Kingdom Protista. They live in quiet or stagnant ponds and are an essential part of the food chain. They feed on algal scum and other microorganisms and other small organisms eat them.

Why are Euglenoids said to photosynthetic and Heterotrophs?

Answer: The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis and can be seen as several rod like structures throughout the cell.

What do eyespots do?

eyespot also called stigma a heavily pigmented region in certain one-celled organisms that apparently functions in light reception. … A cup-shaped mass of pigment rods shields a sensitive area of the flagellar base from light coming from the direction of the opposite end of the organism.
