Yes, the calvin cycle can take place in the absence of light. The products of the light reactions if available can drive the calvin cycle in the absence of light. Basically , a plant needs ATP and NADPH to carry on the calvin cycle where sugar is made. CAM plants are able to produce sugar at night.

What do leaves produce that is stored in starch?
In the leaf excess glucose is rapidly converted to starch. During photosynthesis, plants produce glucose and oxygen, reacting with water and carbon dioxide CO2. But during this process , plants often change some of the glucose into starch, for storage.
What plant produce starch?
In order for plants to make starch, they need some vital factors including; chlorophyll, carbon dioxide and light. Light turns into chemical energy by chlorophyll or chloroplasts (organelles) which forms a chemical reaction that is stored as glucose, the glucose then turns into starch. light Carbon dioxide + water >>>>>>>>>>> Glucose + oxygen
When does starch accumulate in leaves and how do you test for it?
Starch accumulates in leaves during photosynthesis, typically during the day when plants are producing more energy than they need for immediate use. To test for starch in leaves, you can perform the iodine test: boil the leaf in alcohol to remove chlorophyll, then apply iodine solution - if starch is present, the leaf will turn blue-black.
What organism produces starch?
Plants are the primary organisms that produce starch through photosynthesis. They store excess glucose in the form of starch as an energy reserve. Other organisms, such as algae and certain bacteria, can also produce starch through similar biochemical processes.
What part of the plant would you test for starch?
You would test the leaves of the plant for starch. Starch is produced through photosynthesis in the leaves, so they are the best part of the plant to test for the presence of this carbohydrate.
What is the hypothesis of testing leaves for starch?
The hypothesis of testing leaves for starch is that leaves produce starch through photosynthesis and store it for energy. By conducting a test to detect the presence of starch in leaves, we can determine if photosynthesis has occurred in the leaf tissue being tested.
Which leaf contains starch mayana or hydrilla?
Mayana leaves contain starch, while hydrilla leaves do not contain starch. Starch is a carbohydrate storage molecule that plants produce through photosynthesis.
Explain how the cells in the leaves are adapted to their jobs?
they nake starch and produce energy for the plant.
Why fallen leaves does not turn blueblack on being tested with iodine?
Fallen leaves do not turn blue-black when tested with iodine because they lack starch. Starch is a polysaccharide that is stored in plants as a source of energy. Leaves produce starch during photosynthesis in the presence of sunlight, but when the leaves fall, they no longer perform photosynthesis and thus do not store starch in them.
What do leaves produce that is stored in starch?
In the leaf excess glucose is rapidly converted to starch. During photosynthesis, plants produce glucose and oxygen, reacting with water and carbon dioxide CO2. But during this process , plants often change some of the glucose into starch, for storage.
Why do en leaves not turn blue backby iodine?
En leaves do not turn blue-black with iodine because they do not contain starch, which is what iodine reacts with to produce the characteristic color change. Starch is a carbohydrate produced by plants through photosynthesis, so leaves that do not contain starch will not show the blue-black color reaction with iodine.
Why do plants produce glucose?
plants produce glucose because it is there source of food for energy
How do you exract starch from leaves?
You cannot.ANS#2:By the process of Retro-gradation starch can be extracted from leaves.
What plant organ is modified to produce onion bulbs?
The bulb of an onion is formed from modified leaves. While photosynthesis takes place in the leaves of an onion containing chloroplast, the little glucose that is produced from this process is converted in to starch (starch granules) and stored in the bulb.
Is there starch in purple leaves?
Yes, purple leaves can contain starch, as starch is a common carbohydrate storage molecule in plants. Starch can be found in the chloroplasts of plant cells, where it is used for energy storage and can contribute to the purple coloration of leaves.
What plant produce starch?
In order for plants to make starch, they need some vital factors including; chlorophyll, carbon dioxide and light. Light turns into chemical energy by chlorophyll or chloroplasts (organelles) which forms a chemical reaction that is stored as glucose, the glucose then turns into starch. light Carbon dioxide + water >>>>>>>>>>> Glucose + oxygen
Result of starch test on variegated leaves?
Starch test on variegated leaves may show varying levels of starch accumulation in different parts of the leaves. Green parts of the variegated leaves that contain chlorophyll will likely test positive for starch as they can photosynthesize, while white or yellow parts that lack chlorophyll may test negative or have lower levels of starch. This difference in starch accumulation can indicate the distribution of photosynthetic activity in the variegated leaves.
