Question

The food synthesised by the plant is stored as…….....

Answer 1

Hint: Plants are known as photoautotrophs or photosynthetic organisms. It means that using energy from light they are able to synthesize their food directly from carbon dioxide and water.

Complete Answer:
- In plants food is synthesized in leaves in specialized organelles. It is known as chloroplasts. Within the chloroplast the site of food synthesis is grana.
- During photosynthesis, chlorophyll containing cells of leaves in the presence of sunlight, use carbon dioxide and water to synthesize basic sugar called glucose.
- During the process oxygen is released and glucose is formed. The process can be represented as an equation: in the presence of solar energy and by photosynthesis.
$6C{{O}_{2}}+6{{H}_{2}}O\to {{C}_{6}}{{H}_{12}}{{O}_{6}}+6{{O}_{2}}$

- Much of the glucose is produced through photosynthesis and it is immediately metabolized into different forms of energy which the plants use to grow and reproduce.
- Portions of glucose which are not immediately converted to energy, now they are converted to complex sugar compounds, it’s called starches. To build new tissues, plants store starches for future energy. The presence of starch in leaves indicates the occurrence of food stored.

Starch is the food that gets stored in plant leaves.

- Starch is a polymeric carbohydrate. It consists of a large number of glucose units linked by glycosidic bonds. It acts as stored energy in plants.

Note: Plants produce glucose by the process known as photosynthesis. This glucose is converted into starch which is the storage form of carbohydrate in plants.
