Class 7 Science – Chapter 4 Heat: Definition and Explanation of Important Keywords”
In this chapter, we explore crucial heat-related terms like “Celsius scale,” which measures temperature, and “conduction,” the process of heat transfer in solids. “Convection” explains heat flow in fluids, while “radiation” details heat transfer without a medium. Understanding these terms is essential for grasping the science of heat.

Small Intestine- Structure , Functions and Movement in the Digestive System

July 1, 2023July 1, 2023 - by Jaishree Gorane - Leave a Comment

The small intestine of the human digestive system – parts (duodenum, jejunum and ileum), its functions (digestion, absorption) and its structure (villi, layers). Learn about its role in the absorption of nutrients, including vitamins and minerals, how peristalsis drives food and the effects of infections. The anatomy of the small intestine, its functions and its importance to the digestive system

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.

Liver – Structure, Functions, Disorders, Regeneration

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.

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.

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.

Short Note on Mitochondria

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

Mitochondria, the ‘Powerhouse of the cell’, are double-membrane organelles found in eukaryotic organisms. They function as the cell’s digestive system and play an important role in energy production through oxidative phosphorylation. With their unique structure and multiple functions, mitochondria regulate metabolism, promote cell growth, detoxify ammonia, induce apoptosis and maintain calcium ion balance, making them essential for cellular activities.

Human Circulatory System

April 7, 2023April 8, 2023 - by Jaishree Gorane - 5 Comments.

The human circulatory system is responsible for delivering oxygen, nutrients, and hormones to cells and tissues throughout the body. It consists of the heart, blood vessels and blood. The heart pumps oxygenated blood to the body through arteries and the deoxygenated blood returns to the heart through veins. The circulatory system also helps remove waste products from cells and helps regulate body temperature.
