Question

what is ment by photosynthesis ?​

Answer 1

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer 2

Answer:

The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy in the presence of chlorophyll, is called photosynthesis. Oxygen gas is released during photosynthesis. The process of photosynthesis can be represented as:

      $6CO_2$    +    $6H_2O$    +    $Light$ $energy$    →    $C_6H_1_2O_6$    +    $6CO_2$

Photosynthesis takes place in the green leaves of a plant. In other words, food is made in the green leaves of the plant. The green leaves of a plant make the food by combining carbon dioxide and water in the presence of sunlight and chlorophyll.

The carbon dioxide gas required for making the food is taken up by the plant leaves from the air. This carbon dioxide enters the leaves through tiny pores in them called stomata. Water is transported to the leaves from the soil through the roots and stem. The sunlight energy required to carry out the chemical reactions involved in the preparation of food. The green pigment called chlorophyll present in the green leaves helps in absorbing energy from sunlight. Oxygen gas is produced as a by-product during the preparation of food by photosynthesis. This oxygen gas goes into the air.
