Class 7 science -Chapter 6- Physical and Chemical Changes- Definition and Explanation of Important Keywords

October 22, 2023January 19, 2024 - by Jaishree Gorane - Leave a Comment

In the study of physical and chemical changes, understanding key terms is crucial. Chemical Change involves substances transforming into new ones, while a Chemical Reaction rearranges molecular structures. Crystallisation forms solid crystals from solutions, aiding purification. Galvanisation shields iron with a zinc layer to prevent rust. Physical Change alters appearance without changing composition, and Rusting is a destructive corrosion process affecting iron objects.

Class 7 science -Chapter 5-Acids, Bases and Salts – Definition and Explanation of Important Keywords

Class 7 Science Chapter 5 delves into Acids, Bases, and Salts, demystifying their definitions, examples, and properties. Acids are sour, turn litmus red, and release H+ ions, whereas bases are slippery, turn litmus blue, and release OH- ions. Neutral substances balance acidic and basic traits, while neutralisation forms salts through acid-base reactions, crucial in everyday applications.

Chapter 1- Nutrition in Plants -Class 7 – Detailed Notes

July 3, 2023December 30, 2023 - by Jaishree Gorane - Leave a Comment

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.

The Pancreas – Structure, Function and Hormonal Secretions

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

The pancreas is a glandular organ located in the abdominal cavity. It has a complex structure consisting of various parts, including the head, body, and tail. Functionally, the pancreas plays a crucial role in both the digestive and endocrine systems. It produces and secretes digestive enzymes and juices, essential for the breakdown and absorption of nutrients. Additionally, the pancreas secretes important hormones like insulin and glucagon, which regulate blood sugar levels. The pancreatic structure, function, and hormonal secretions are vital for maintaining overall health and metabolic balance.

The liver, a vital organ known for its remarkable structure and function, comprises four lobes: right, left, caudate, and quadrate. It is supported by the falciform ligament and surrounded by Glisson’s capsule. The liver’s crucial components include the common hepatic duct, hepatic artery, hepatic portal vein, lobes, lobules, and the protective peritoneum. Its intricate structure enables it to perform vital functions in the body.

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.

Chloroplast – Definition, Structure, Distribution, function and Diagram

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.
