Humans reproduce by sexual method. The male reproductive system is located in the pelvis region. It includes a pair of testis along with accesory ducts, glands and external genitalia. Male Reproductive System -  Testes are located outside the abdominal cavity within a pouch called scrotum scrotum maintenance the low temperature (2-2.5 °C lower the normal body temperature) which is required for spermatogenesis. Testis is oval shaped, and each testis is internally divided into 250 compartments known as testicular lobules. Each testicular lobule has 1 to 3 seminiferous tubule. Sertoli sells provide nutrition to the germ cells. Leydig cells synthesize and secret androgens like testosterone.

Mind map  of Solutions and their Significance in Chemistry NEET Exam PDF of mind map is given at end of this page Introduction: The concept of "Solutions" is a fundamental and essential topic in chemistry, forming the basis for various aspects of chemical reactions and processes. This blog post will explore the key topics covered in the Class 12 NCERT chapter on Solutions, which are not only important for academic understanding but also hold significant relevance for the NEET exam. We'll delve into types of solutions, solubility, vapor pressure of liquid solutions, Raoult's law, ideal and non-ideal solutions, and colligative properties such as relative lowering of vapor pressure, elevation in boiling point, depression in freezing point, osmotic pressure, and abnormal molar mass. 1. **Types of Solutions:**    - Solutions are homogeneous mixtures of two or more substances, where the solute is uniformly distributed in the solvent. The three main types of solutions are: ...

Chemical Bonding and Molecular Structure Simplified: A Comprehensive NEET Exam Guide Chemical bonding and molecular structure are fundamental concepts in chemistry that form the basis of understanding the properties and behavior of matter. For NEET exam aspirants, a thorough understanding of these topics is crucial. In this article, we will delve into the essential aspects of chemical bonding and molecular structure, providing detailed explanations and including relevant formulas. 1. Kossel Lewis Approach: The Kossel Lewis approach, also known as Lewis dot structures, helps represent the valence electrons of atoms using dots. The number of valence electrons for each element can be determined from its group number in the periodic table. To draw a Lewis dot structure: - Write the symbol of the element. - Place dots around the symbol, representing valence electrons. - Follow the octet rule (except for hydrogen and helium), which states that atoms tend to gain, lose, or share electrons to ...

The PDF is given at end of this page👇👇 The plant kingdom is a diverse group of organisms that exists on land and in aquatic environments. Plants are the primary producers in most ecosystems, providing food and shelter for other organisms. Plants have a long evolutionary history, and there are millions of species of plants in the world today. In this article, we will discuss the classification of the plant kingdom, the structure and function of plants, and the importance of plants in our ecosystems.  Classification of the Plant Kingdom The plant kingdom is divided into two major groups: vascular plants and nonvascular plants. Vascular plants are those that have a vascular system that transports water and nutrients throughout the plant body. Examples of vascular plants include trees, ferns, and grasses. Nonvascular plants, on the other hand, lack a vascular system and must rely on other methods for transporting water and nutrients. Examples of nonvascular plants include mosses and ...

Structure of atom Mind map Atomic structure class 11 Chemistry Best revision shortnotes PDF is given at end of this page👇👇 Atoms are the building blocks of elements. They are the smallest parts of an element that chemically react. The first atomic theory, proposed by John Dalton in 1808, regarded atom as the ultimate indivisible particle of matter. Towards the end of the nineteenth century, it was proved experimentally that atoms are divisible and consist of three fundamental particles: electrons, protons and neutrons. Atoms are the basic building blocks of all matter. They are composed of three main components: protons, neutrons, and electrons.  Protons are positively charged particles located in the nucleus of an atom. The number of protons in an atom is called its atomic number and determines the element it belongs to.  Neutrons are electrically neutral particles also found in the nucleus of an atom. They help to keep the nucleus stable. The total number of neutrons and p...

Periodic Table - Classification of Elements and Periodic Properties mind map Class 11 PDF is given at end of this page In this Unit, you have studied the development of the Periodic Law and the Periodic Table. Mendeleev’s Periodic Table was based on atomic masses. Modern Periodic Table arranges the elements in the order of their atomic numbers in seven horizontal rows (periods) and eighteen vertical columns. Atomic numbers in a period are consecutive, whereas in a group they increase in a pattern.  The periodic table is a tabular arrangement of elements that organizes them according to their atomic number, electron configuration, and recurring chemical properties. The table is organized into vertical columns (called groups) and horizontal rows (called periods). Each element in the periodic table is represented by its atomic symbol, atomic number, and its average atomic mass. The periodic table was first proposed by Russian chemist Dmitri Mendeleev in 1869. He organized the 63 known...
