Question

Answer

Product of photosynthesis(carbohydrates) are stored in the form of starch in plants.
it'sa fact my dear
please go through the ncert book ones again and i am dam sure about it that you will be able to answer all the questions

Answer

Plant make food in form of glucose store In form of starch and transportation occur in form of sucrose

glucose get converted to glycogen to release energy

Fructose is basically for plant growth and development
and in animals it is directly absorbed in blood stream. .

Answer

The food stored in leaves is primarily in the form of starch. Starch is a complex carbohydrate that serves as a reserve energy source in plants. It is made up of glucose molecules linked together in long chains.

Here is a detailed explanation of why starch is the correct answer:

1. Food Storage in Leaves:
Plants produce their own food through photosynthesis, which occurs mainly in the leaves. During photosynthesis, plants convert sunlight, carbon dioxide, and water into glucose, the primary source of energy. This glucose is then transported to different parts of the plant to be utilized or stored.

2. Glucose Production:
During photosynthesis, plants synthesize glucose molecules from carbon dioxide and water, using sunlight as an energy source. Glucose is a simple sugar that can be readily utilized by the plant for energy production.

3. Conversion to Starch:
As glucose is produced during photosynthesis, it is quickly converted into starch for storage. Starch is a more stable form of energy storage compared to glucose, as glucose can be rapidly metabolized and used up. Starch, on the other hand, can be stored for longer periods and broken down when needed.

4. Structure and Storage of Starch:
Starch is composed of long chains of glucose molecules linked together. These chains can be branched or unbranched, forming a compact granule structure. This compact structure allows starch to be stored efficiently within specialized storage structures, such as chloroplasts or amyloplasts, found in plant cells.

5. Function of Starch in Leaves:
Starch serves as an energy reserve for plants during periods when photosynthesis is limited or unavailable. In leaves, starch accumulation occurs during the day when photosynthesis rates are high. At night or during periods of low light, starch is broken down to glucose and used for energy production to support metabolic processes.

6. Other Forms of Carbohydrates:
While starch is the primary form of food storage in leaves, it's worth mentioning that other carbohydrates like glucose, fructose, and glycogen can also be present in small amounts. Glucose and fructose are simple sugars that are produced during photosynthesis and can be used directly for energy production or transported to other parts of the plant. Glycogen, on the other hand, is a form of energy storage found in animals, including humans, and is not typically present in plant tissues.

In conclusion, starch is the primary form of food storage in leaves. It provides a stable and efficient way to store excess glucose produced during photosynthesis, ensuring a readily available energy source for the plant when needed.
