Chemosynthesis – Definition, Process, Equation, Chemosynthetic bacteria , types , examples

June 22, 2023June 23, 2023 - by Jaishree Gorane - Leave a Comment

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.

Equation for Photosynthesis

June 18, 2023June 18, 2023 - by Jaishree Gorane - Leave a Comment

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.

Importance of Photosynthesis

June 16, 2023June 16, 2023 - by Jaishree Gorane - Leave a Comment

Photosynthesis is vital and sustains life on earth. It produces oxygen, drives plant growth and forms the basis of the food chain. Animals depend on photosynthesis to produce oxygen and feed themselves. Plants thrive on energy production and nutrient synthesis. Humans benefit from food sources and renewable energy sources. Nature finds a balance as photosynthesis reduces carbon dioxide and promotes biodiversity.

Photorespiration occurs in

June 10, 2023June 10, 2023 - by Jaishree Gorane - Leave a Comment

Photorespiration occurs in C3 plants and involves several organelles. In chloroplasts, RuBP oxygenase reacts with RuBP, leading to the formation of PGA and PGly. Glycolic acid is produced in chloroplasts and then undergoes oxidation in peroxisomes, forming glyoxylic acid. Within mitochondria, glycine combines with CO2 and NH3, releasing CO2 and forming serine.

Photorespiration is a Wasteful process Justify

June 10, 2023June 10, 2023 - by Jaishree Gorane - Leave a Comment

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.

Crassulacean Acid Metabolism (CAM) -Pathway, Significance, Examples

June 10, 2023June 10, 2023 - by Jaishree Gorane - Leave a Comment

Crassulacean Acid Metabolism (CAM) is a specialised form of photosynthesis in xerophytic succulents. CAM Plants absorb CO2 at night, store it as malic acid and release it during the day for carbohydrate production. They conserve water by closing the stomata during the day. Examples are orchids, cacti, aloe and pineapple. CAM enables efficient CO2 use, water conservation and reduced photorespiration in arid environments.

Name the factors affecting Photosynthesis

June 7, 2023June 7, 2023 - by Jaishree Gorane - 1 Comment

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.

Chloroplast – Definition, Structure, Distribution, function and Diagram

June 1, 2023June 22, 2023 - by Jaishree Gorane - 1 Comment

Chloroplasts, 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.

Salivary Glands – Definition, Types, Location, Size, Ducts, Diagram, Characteristics, Secretion, Structure and Function

May 30, 2023June 2, 2023 - by Jaishree Gorane - Leave a Comment

Salivary glands are exocrine glands responsible for saliva secretion. They have acinar cells for saliva synthesis and ductal cells for transport. Myoepithelial cells aid saliva movement. Major glands include parotid (largest), submandibular, and sublingual (smallest). Ducts are Stensen’s (parotid), Wharton’s (submandibular), and multiple (sublingual). Saliva lubricates, digests, and protects. Understanding their structure and function is vital.

Gastric Glands – Location , Structure, Types, Secretion and Functions

May 29, 2023May 29, 2023 - by Jaishree Gorane - 1 Comment

Gastric glands, present in the stomach lining, play an important role in digestion. Structurally, they are made up of different cell types, including parietal, chief, and mucous cells. These glands secrete gastric juice, which consists of hydrochloric acid, pepsinogen and mucus. The secretions help break down food, sterilisation of ingested pathogens and absorb essential nutrients, thus fulfilling important functions in the digestive process
