SOLAR ECLIPSE 2025

-
   Introduction to Solar Eclipses Solar eclipses are one of the most fascinating celestial events, capturing the curiosity of scientists, astronomers, and the general public alike. These occur when the Moon passes between the Earth and the Sun, either partially or completely obscuring the Sun's light. There are different types of solar eclipses: Total Solar Eclipse : The Moon completely covers the Sun. Partial Solar Eclipse : The Moon partially blocks the Sun, creating a crescent shape. Annular Solar Eclipse : The Moon covers the center of the Sun, leaving a ring-like appearance. Hybrid Solar Eclipse : A rare eclipse that transitions between total and annular phases. The Solar Eclipse of 2025 In 2025, two significant solar eclipses will occur: March 29, 2025 – A partial solar eclipse , visible in several parts of the world but not visible from India . September 21, 2025 – Another partial solar eclipse , with possible limited visibility in India. Key Details of the March 29, ...

CELL STRUCTURE AND FUNCTION NCERT HIGHLIGHTS

 Cell Structure and Functions: Cytology, the Science of Cells: Let's begin with cytology, which is the scientific study of cells. It delves into the form, structure, and composition of these tiny units of life. The Cell: Life's Building Block: A cell is the fundamental structural and functional unit of life. Think of it as the building block of living organisms. In unicellular organisms like amoeba and bacteria, a single cell performs all essential life functions. Cell Theory Founders: Back in the day, Anton Von Leeuwenhoek was the first to observe and describe live cells under a microscope. Later, Robert Brown discovered something crucial, the nucleus. Cell Theory, the Bedrock of Biology: In the mid-19th century, Matthias Schleiden and Theodore Schwann put forth the cell theory. It stated that all living organisms are made up of cells and their products. Furthermore, they emphasized that all cells come from pre-existing cells. This theory was later refined by Rudolf Virchow. ...

 All living organisms are made up of cells. Unicellular organisms consist of a single cell that performs all basic functions. In multicellular organisms, there are millions of specialized cells. Specialized cells in multicellular organisms carry out specific functions efficiently. Different groups of cells are responsible for different specialized functions. Muscle cells in humans contract and relax for movement, nerve cells carry messages, and blood transports oxygen, food, hormones, and waste materials. In plants, vascular tissues conduct food and water throughout the plant. Multi-cellular organisms exhibit division of labor, where specific functions are carried out by clusters of cells in a definite place in the body. These clusters of cells are called tissues. Tissues are arranged and designed to maximize efficiency in performing their functions. Examples of tissues include blood, phloem, and muscle. A tissue is formed by a group of cells that are similar in structure and/or wo...
