what do you mean by photosynthesis,
Answers
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:
here is ur answer
photosynthesis is the process in which organic ones are utlised to form inorganic ones
Photosynthesis includes series of chemical reactions which are carried out in chloroplast,i.e.The specialized structures found on cells of plants. In these series of reaction, water and carbon dioxide are converted into glucose and in this reaction energy from sunlight is used. Because, it is an endothermic reaction, the entire process requires input of energy. Photosynthesis is also classified as oxidation – reduction reaction as it includes loss of electrons by water and gain of electrons by carbon dioxide.
The process of photosynthesis takes place in Mesophyll Cells and the carbon dioxide required by the process enters the process via stomata, i.e. the small holes present on the outer layer of leaves. The water required for the process is transported via roots through the vascular tissues.
The chloroplast contains membranous system (shown in image below) consisting of the stroma lamellae, grana and the fluid stroma. The membrane system traps the light energy and helps in synthesizing ATP and NADPH. Following diagram shows the electron micrograph of a section of chloroplast
which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll. Light energy is absorbed by the green chemical chlorophyl
e, C6H12O6 is glucose and O2 is released from water..”
All animals and human beings are dependent on plants for food and these plants synthesize the food via physio – chemical process called Photosynthesis.
It is the primary source of food.
It results in the release of oxygen in atmosphere.
