What is a good question for photosynthesis?

Where is the energy used in photosynthesis obtained? What are the reactants for photosynthesis? What are the end products of photosynthesis? In which part of the leaf does photosynthesis primarily occur?

What is photosynthesis questions and answers?

Answer: Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials.

What is photosynthesis Mcq?

MCQ on Photosynthesis Photosynthesis is the process by which plants, algae and some bacteria use sunlight, carbon dioxide and water to prepare their food. This is a biogeochemical process in which light energy is converted into chemical energy. Photosynthesis takes place in the chloroplast.

What Colour is chlorophyll?

green color
Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

Which substance is not used in photosynthesis?

So, the correct answer is ‘Iodine solution’.

What gives the green color of leaves?

chlorophyll
The green coloration in the leaves of most plants is due to the presence of chlorophyll, a pigment used to absorb energy from the sun.

Why are plants usually green?

Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

Why photosynthesis is called dark reaction?

Instead, dark reaction uses ATP and NADPH to produce energy molecules. No photosystem is required. Photolysis of water does not occur. So, the dark reaction in photosynthesis is called so because it does not require light energy.

Where are thylakoids and grana located?

chloroplast
Thylakoids are located as stacks called grana in the stroma (matrix) of chloroplast.

What is found in chlorophyll?

Chlorophyll is the major pigment used by plants for capturing light energy. A chlorophyll molecule consists of a porphyrin head (four pyrrole rings containing nitrogen arranged in a ring around a magnesium ion) and a long hydrocarbon tail. The hydrocarbon tail is lipid-soluble.

Why are plants red?

Plants of different colors contain other pigments, such as anthocyanins, which are responsible for reds and purples; anthoxanthins, which reflect yellow; and carotenoids, which reflect yellow, orange, or red. When plants change colors in autumn, it is due to their having a mixture of these pigments.

Who discovered photosynthesis?

Jan Ingenhousz, (born December 8, 1730, Breda, Netherlands—died September 7, 1799, Bowood, Wiltshire, England), Dutch-born British physician and scientist who is best known for his discovery of the process of photosynthesis, by which green plants in sunlight absorb carbon dioxide and release oxygen.

Where is chlorophyll located?

chloroplasts
Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. This is where photosynthesis takes place.

What sugar is formed in photosynthesis?

glucose
Used by the majority of plants, it involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become a sugar called glucose.

What color light is best for photosynthesis?

The majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.

Which plant is C4?

C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. This step takes place in the mesophyll cells that are located close to the stomata where carbon dioxide and oxygen enter the plant.

Why is Calvin cycle called C3 cycle?

The conversion of CO2 to carbohydrate is called Calvin Cycle or C3 cycle and is named after Melvin Calvin who discovered it. The plants that undergo the Calvin cycle for carbon fixation are known as C3 plants. Calvin Cycle requires the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase commonly called RuBisCO.

What is the purpose of photosynthesis in biology?

What Is the Purpose of Photosynthesis? Photosynthesis is a process that allows plants to harvest energy in sunlight and store it chemically, by producing sugars. Sugars hold energy in their molecular bonds; when the plant breaks down these bonds, energy is released that the organism can then use.

What are some photosynthesis questions?

– Oxygen and water are converted into glucose sugar and carbon dioxide. – Carbon dioxide and water are converted into glucose sugar and oxygen. – Sugar is broken into water and oxygen. – Carbon dioxide and oxygen are converted into glucose sugar and water.

What are the basics of photosynthesis?

Photosynthesis is the process through which plants convert light energy from the sun to chemical energy. During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen and glucose. Lets have a look at the process of photosynthesis and also explore its importance.

What organisms can carry on photosynthesis?

They include the plants, algae and certain protists bacteria. the organisms that carry out photosynthesis to acquire energy. They use the energy from sunlight to convert carbon dioxide and water into organic material to be utilized in cellular functions such as biosynthesis and respiration.
