what is the organelle where photosynthesis occurs

Term Meaning
Chloroplast The plant cell structure where photosynthesis occurs
Thylakoids Disc-like structures within a chloroplast that help absorb light
Grana Stacks of thylakoids in a chloroplast
Chlorophyll A pigment found in the thylakoid that absorbs light energy and uses it to produce carbohydrates

What is photosynthesis and where does it occur Class 10?

Photosynthesis takes place in the chloroplasts that have chlorophyll present in them. It is the chlorophyll that absorbs light energy from the sun. There are tiny pores called stomata that function as roadways for carbon dioxide to enter and oxygen to leave the plant.

Where in the chloroplast does photosynthesis occur?

thylakoids
Photosynthesis: The Basics 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).Mar 3, 2021

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.

Where does photosynthesis occur 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.

Which molecule is a reactant of photosynthesis?

During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Which type of molecule is produced during photosynthesis apex?

Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules and release oxygen as a byproduct into the atmosphere.

Is photosynthesis anabolic or catabolic?

Photosynthesis, which builds sugars out of smaller molecules, is a “building up,” or anabolic, pathway. In contrast, cellular respiration breaks sugar down into smaller molecules and is a “breaking down,” or catabolic, pathway.

What role does chloroplast play in photosynthesis?

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

What kind of molecule is chlorophyll?

Chlorophyll is the green pigment in plants, algae, and cyanobacteria that is essential for photosynthesis. Its central structure is an aromatic porphyrin or chlorin (reduced porphyrin) ring system with a sequestered magnesium atom. A fifth ring is fused to the porphyrin.

What molecule was produced from the energy of plants electron?

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of the electron carrier molecule NADPH (nicotinamide adenine dinucleotide phosphate) and the energy currency molecule ATP (adenosine triphosphate).

Where does photosynthesis occur in the biosphere?

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

In what cell organelle does photosynthesis occur answer key?

Explanation: Photosynthesis occurs in the chloroplasts of the plant, which have chlorophyll and can capture light for the plant to use that energy and start the chemical reaction. Inside the chloroplasts are things called thylakoid membranes, which drive the light-dependent reactions of photosynthesis.

What are the two location of photosynthesis?

Location of Photosynthesis

Photosynthesis occurs in chloroplasts found in the leaves and green stems of plants.

In which part of a chloroplast does Phase 1 occur?

In the thylakoid membrane of the chloroplast, each stage of light reaction occurs.

What is ADP and NADP?

ATP – Adenosine triphosphate. ADP – Adenosine diphosphate. NADP – Nicotinamide adenine dinucleotide phosphate. NADPH – The reduced form of NADP. In the Light Dependent Processes i.e Light Reactions, the light strikes chlorophyll a in such a way as to excite electrons to a higher energy state.

In which region most of the photosynthesis takes place?

In plants, photosynthesis takes place in chloroplasts of the leaves, which contain the chlorophyll. Complete answer: Maximum and minimum photosynthesis takes place in the blue and green light, respectively. Since the photosynthesis takes place in the chloroplast that has chlorophyll.

Where does photosynthesis occur Class 9?

In the chloroplast. Plants have specific structures unique to them known as chloroplasts. It contains chlorophyll – the most important pigment that drives the photosynthesis process.

What is photosynthesis for class 7th?

The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. The process of photosynthesis takes place in the leaves of a plant.

Which three events occur during photosynthesis?

The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.

What part of photosynthesis occurs in the thylakoid?

The light-dependent reactions
The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.

Does photosynthesis occur in stems?

Plant photosynthesis occurs in leaves and green stems within specialized cell structures called chloroplasts. … Additional light-trapping pigments, enzymes (organic substances that speed up chemical reactions), and other molecules needed for photosynthesis are also located within the thylakoid membranes.

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.

Which organelle is involved in photosynthesis list and describe the parts of this organelle?

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.

Does photosynthesis occur in ribosomes?

Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. … These are chloroplasts, the organelles which conduct photosynthesis in plants and algae. Chloroplasts closely resemble some types of bacteria and even contain their own circular DNA and ribosomes.

Where do the reactants for photosynthesis come from?
