How is starch linked to photosynthesis?
Green plants are producers. This means that they can survive without animals! They can make lots of organic chemicals from a few simple inorganic chemicals. They need simple things like carbon dioxide and water and can make complex things like sugar, starch, fat, and proteins.
What is the name of the chemical that plants often store their food?
Glucose.
In which two regions of the gut does starch digestion take place?
Starch digestion primarily takes place in the mouth and small intestine. In the mouth, the enzyme amylase breaks down starch into smaller glucose units. Further breakdown and absorption of glucose occur in the small intestine with the help of other digestive enzymes.
The glucose making part of photosynthesis takes place where?
The glucose-making part of photosynthesis, known as the Calvin cycle, takes place in the stroma of the chloroplast. This cycle uses the products of the light-dependent reactions (ATP and NADPH) to convert carbon dioxide into glucose.
How do plants reproduce foods?
Plants produce their own food through a process called photosynthesis, where they use sunlight, carbon dioxide, and water to make glucose (sugar) and oxygen. This process takes place in the chloroplasts of plant cells, specifically in the leaves. The glucose produced serves as food for the plant, and excess glucose is stored as starch for later use.
How does the presence of starch show photosynthesis has taken place?
The presence of starch indicates that photosynthesis has taken place because starch is a storage form of glucose produced during photosynthesis. This process involves converting light energy into chemical energy, which is used to synthesize glucose. Starch is the final product of this conversion and serves as a long-term energy store in plants.
How does starch's location in leaves prove photosynthesis?
To clarify: We boiled alcohol with a leaf and tested for starch with iodine (present in the veins), We also covered a leaf with tin foil and came back the next day. The leaf was more green in the veins and more discolored farther away from the veins. This lab was suppose to show us glucose is made by the leaf, but all it proves is that starch is in the veins, right?
How do you know photosynthesis has taken place?
I order to know if photosynthesis has taken place, you need to know whether it has made it's own food (glucose) by adding iodine to one sample of a leaf. If it turned black, then it has glucose in it, if brown, then no glucose in it. Then you need to find if it has stored starch. That's what you find and if you found the answer please continue on this and explain in more.

Why leaves have starch?
Starch is the main carbohydrate found in plant tubers and seed endosperm in the form of granules. Starch contains mylose and amylopectin molecules. It is found in various carbohydrates such as white bread, potatoes, beans and rice.
Can plants store sucrose as starch?
Yes, plants can convert sucrose into starch for storage. Sucrose is broken down into glucose and fructose, which are then used to synthesize starch molecules. This process allows plants to store excess sugars for later use.
Where in a plant cell does glucose form?
Glucose is formed in plant cells through the process of photosynthesis, which takes place in the chloroplasts. During photosynthesis, light energy is converted into chemical energy, allowing the plant to produce glucose from carbon dioxide and water.
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.
The neccessity of factor for photosynthesis?
Carbon dioxide and glucose is essential for photosynthesis to take place. The equation for photosynthesis; carbon dioxide + glucose = oxygen + water. This can be reversed for the respiration equation.
What would be the conclusion after testing a leaf for starch?
Starch is produced by leaves during Photosynthesis, therefore if the leaf has not been exposed to light then it will not contain starch, and so when tested the Iodine will stay Yellow/Brown. Consequently if the leaf has been left in the light Photosynthesis will have taken place and when tested the Iodine will go Blue/Black showing that Starch is present. Hope this helps :)

Where does glucose-making take place in photosynthesis?
It is the dark reaction.It takes place in stroma.
