Nutrition in plants encompasses various processes, including photosynthesis, where chlorophyll in leaves captures sunlight to convert carbon dioxide and water into glucose and oxygen. Stomata, tiny openings on leaves, facilitate gas exchange. Other modes of nutrition include parasitic plants, insectivorous plants that capture and digest prey, and saprotrophic nutrition involving decomposers. Symbiotic relationships, like with Rhizobium bacteria, aid nutrient replenishment in the soil.

Chemosynthesis is a process where chemosynthetic bacteria convert inorganic compounds into energy-rich organic compounds. It occurs in environments lacking sunlight. The equation for chemosynthesis is carbon dioxide + water + inorganic compounds → organic compounds + sulphur compounds. Chemosynthetic bacteria, like sulphur bacteria, iron bacteria, and nitrifying bacteria, are examples of organisms that carry out chemosynthesis. Chemosynthesis differs from photosynthesis in energy sources and reactions.

Photosynthesis, the process by which plants convert sunlight into energy, can be summarised by the equation for photosynthesis. The chemical equation, 6CO2 + 6H2O + light energy → C6H12O6 + 6O2, represents the balanced reaction. It outlines the conversion of carbon dioxide and water into glucose and oxygen with the help of sunlight. This word equation simplifies the process for easier understanding.

Photorespiration is a wasteful process that inhibits photosynthesis by diverting RuBisCO activity from carbon fixation. It reduces the production of glucose and oxygen, important products of photosynthesis. In addition, photorespiration consumes ATP instead of producing it, resulting in a loss of energy for the plant. It also leads to a loss of fixed carbon through the release of carbon dioxide, which further reduces carbon gain.

Photosynthesis is influenced by various factors. Light intensity, temperature, carbon dioxide content and the availability of water are decisive factors. Sufficient light energy is crucial for the process, while an optimal temperature ensures enzyme activity. Sufficient carbon dioxide is necessary and water availability affects stomatal opening. Together, these factors affect the speed and efficiency of photosynthesis in plants.
Name the factors affecting Photosynthesis Read MoreChloroplasts, found in plant cells, are defined as organelles that contain chlorophyll. They have a complex structure with outer and inner membranes, stroma, thylakoid membranes and grana. Functionally, chloroplasts play a key role in photosynthesis. They convert light energy into chemical energy, produce ATP and oxygen and fixing carbon dioxide. The diagrams illustrate the structure and functions of chloroplasts in plant metabolism.
