Question

Please answer these Five questions. ​

Answer 1

1)the process by which green plants turn carbon dioxide and water into food using energy from sunlight is called photosynthesis

2)carbon dioxide, sunlight

3)Sunlight, chlorophyll, carbon dioxide and water are the necessary conditions required for photosynthesis.

4)Guard cells control stoma and other organs in plants, their opening and closing to moderate the process of respiration.

5)Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.

Answer 2

Answer:

1. 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.

3.

Sunlight, chlorophyll, carbon dioxide and water are the necessary conditions required for photosynthesis.

Explanation:

4. Guard cells are specialized plant cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore. The stomatal pores are largest when water is freely available and the guard cells turgid, and closed when water availability is critically low and the guard cells become flaccid. Photosynthesis depends on the diffusion of carbon dioxide (CO2) from the air through the stomata into the mesophyll tissues. Oxygen (O2), produced as a byproduct of photosynthesis, exits the plant via the stomata. When the stomata are open, water is lost by evaporation and must be replaced via the transpiration stream, with water taken up by the roots. Plants must balance the amount of CO2 absorbed from the air with the water loss through the stomatal pores, and this is achieved by both active and passive control of guard cell turgor pressure and stomatal pore

5. Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.” The term “autotrophic” is formed by the combination of two terms, “auto” meaning self, and “trophic” meaning nutrition.
