Nutrition in Plants Class 7

- 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.

How are Nutrients Replenished in the Soil?

- by Jaishree Gorane - Leave a Comment

Nutrients in the soil are replenished through the roles of decomposers and nitrogen fixation. Decomposers break down organic matter, releasing inorganic nutrients back into the soil. Nitrogen fixation converts atmospheric nitrogen into a usable form for plants. Conservation methods like organic farming, crop rotation, and conservation tillage help maintain soil fertility. These processes sustain nutrient replenishment and support sustainable agriculture.

The Pancreas – Structure, Function and Hormonal Secretions

- 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.

Structure and functional units of the Liver

- by Jaishree Gorane - 1 Comment

The liver, a vital organ in the human body, consists of numerous structural and functional units called Hepatic lobules. Each lobule consists of hepatic cells, sinusoids and a central vein. The hepatocytes in the lobules perform various metabolic functions, such as detoxification, protein synthesis and bile production. Understanding the intricate structure and function of the liver units is crucial to understanding liver physiology.

Difference Between Pollination and Fertilisation

- by Jaishree Gorane - Leave a Comment

Understanding the difference between pollination and fertilisation is crucial in plant reproduction. Pollination is the transfer of pollen from the stamen to the pistil, whereas fertilisation is the fusion of male and female gametes to form a zygote. Pollination occurs before fertilisation and can lead to genetic variation. These processes play an important role in the successful reproduction of plants.

Difference Between Chemosynthesis and Photosynthesis

- by Jaishree Gorane - Leave a Comment

Chemosynthesis and photosynthesis are two different processes with different energy sources and reactions. While photosynthesis uses light energy, carbon dioxide and water to produce glucose and oxygen, chemosynthesis relies on chemical energy from inorganic compounds and produces organic compounds without the involvement of light or oxygen.
