There are 5 main subjects and each of values in the exam. Out of these five subjects Science has been the most interesting subject for many and it is indeed. The exams are further divided into 2 sections namely SA-1 and SA-2. Further the science has three sections for Class X , namely Physics, Biology and Chemistry. This course is particularly on Biology specially covering SA-2. In this Course you will study various chapters of biology which covers the entire syllabus with concepts and important questions generally asked in the exam. The syllabus covers two chapters in biology: Reproduction & Heredity and Evolution. Besides this we will provide you lectures on Our Environment and Management of natural resources. In Reproduction you will learn Reproduction in animal and plants (asexual and sexual) reproductive, health need for and methods of family planning, safe sex vs HIV/AIDS, Child bearing and women's health. Heredity and Evolution involves Meaning of Heredity, Mendel's Contribution- Law of Inheritance of traits, sex determination, Brief introduction and concepts of evolution. Our Environment includes Ecosystem, Environmental Problem, Ozone depletion, waste production and their solution, Biodegradable and Non- Biodegradable. In Management of Natural Resources you will learn about natural resources, conservation and judicious use of natural resources, Forest and wild life, coal and petroleum conservation. Examples of peoples participation in conservation of natural resources. These chapters are quite new but Sameer Sir has made it the easiest ever. You will understand everything and if you have any queries you can mail us at mail@studykhazana.com
Reproduction and Our Environment | CBSE Class 10 Biology (Class X Science)

Section 1: REPRODUCTION (In this section there are 5 lectures all preparing you to the best. All the lectures are very important and requires your utmost concern. You will find all the important topics and the types of questions asked. With these lectures we are sure biology will be your favorite subject. In Reproduction you will learn Reproduction in animal and plants (asexual and sexual) reproductive, health need for and methods of family planning, safe sex vs HIV/AIDS, Child bearing and women's health, brief introduction, Basic concepts of evolution. These chapters are quite new but Sameer Sir has made it the easiest ever. You will understand everything and if you have any queries you can mail us at mail@studykhazana.com)
Lecture 1 Reproduction Part-1 (In this video you will begin with the definition of Reproduction in terms of science then you will understand the significance of Reproduction i., it is the process that ensures the existence of life. Further Reproduction is classified into 2 section and they are Asexual Reproduction and Sexual Reproduction. You will able to differentiate between both which is very important for understanding as well as for examinations as well. In Asexual Reproduction you will study Binary Fission, Multiple fission, Budding, Spore Formation and Vegetative Propagation. There are three types of questions generally asked in the exam. 1) Define 2) Draw the diagram and Explain the Process...... 3)Explain the organism which reproduce by........ In the next section you will study about the sexual reproduction in plants and sexual reproduction in animals. In this sections you will also study about Sexually Transmitted Diseases, how are they spread and what are the different methods of birth control.)
Lecture 2 Reproduction Part-2 (The lecture-2 starts with Asexual Reproduction. There are six types of asexual reproduction and they are Binary Fission, Multiple fission, Budding, Spore Formation, Fragmentation, Regeneration and and Vegetable Propagation. We will begin with Binary Fission in which you will see the binary fission of amoeba and the entire process has been shown to you by some labelled diagrams. Then you will get some very important notes on Binary fission, Multiple Fission, Budding in hydra, Budding in yeast, Spores Formation Rhizopus Fungus, Regeneration in Planaria, Fragmentation in Spirogyra, Vegetative Propagation and types of vegetative propagation. You will also learn about the organism following more than one asexual reproduction. You will get a clear idea on the differences among these methods. You can note down these jotted points. The notes provided to you is good enough to study and prepare for exam. These notes are specially made for you.)
Lecture 3 Reproduction Part-3 (Lecture is a continuation of Lecture-2 where you will begin with tissue culture then you will learn its advantages, advantages of vegetative propagation and hence the asexual reproduction topic finishes here. Moving further ahead you will understand asexual reproduction, hormones and their effects. The sexual reproduction in plants and animals both are discussed here. In plant you will learn parts of plants with labelled diagram. You will learn Female and Male reproductive parts of the plant. Everything is provided to you in the form of the notes. You are requested to pause the video and note the notes provided to you. They are prepared by Sir and are the best notes. If you have any query please do not hesitate to mail us at mail@studykhazana.com. This lecture not only teaches you the chapter but also any lessons of life.)
Lecture 4 Reproduction Part-4 (You will begin with revision of Fertilization in a flower with labelled diagram and difference between triple fusion and syngamy. You will learn reproduction in animals, gametes: both male and female gamete, How Sexual Reproduction in animal takes place, External and Internal fertilization, Puberty, changes that occurs at adolescence, Male Reproductive system, female reproductive system, sexual cycle in reproduction, fertilization in human beings and Development of Embryo. Proper explanation to everything is provided to you.)
Lecture 5 Reproduction Part-5 (This is the last lecture wherein you will learn Birth Control. Birth control is basically the practice of preventing unwanted pregnancies, using contraception. It is done in three ways Barrier Method, Chemical Method and Surgical Method. The first two methods are said to be Temporary methods. Further you will learn more about these method by Sameer Sir. You will find some very important questions and are usually asked in the exam. Thereupon you will get to know about female foeticide, Sexually transmitted diseases and at the end of the video you will counter a quiz.)
Section 2: OUR ENVIRONMENT (In this section you will learn about environment. At the end of the lectures student will be able to: 1) Explain the various types of waste being added to the environment. 2) Classify the various components and their inter-relationship in an ecosystem. 3) Predict the consequences due to human activities which affect the environment. 4) Analyse Reason for Ozone Depletion. 5) Interpret management of garbage disposal in own words.)
Lecture 1 Our Environment- I (Our Environment is the surrounding in which we live which includes the physical surrounding like temp, air, water bodies and soil. All the plants and animals live in that surrounding. The waste material produced by man and animals are poisonous to some extend. These waste are classified into two groups: 1) Biodegradable 2) Non-Biodegradable Ecosystem is a self contained unit of living things( plants, animals and decomposers) and their non-living components like soil, air and water. eg:- Grassland. It has two components: Biotic and Abiotic components. Biotic component inlcudes the three types of organisms: 1) Producers 2) Consumers 3) Decomposers. Producers are which entraps the solar energy and make their food or energy for other organisms. Consumers are organisms that are dependent on the food or the energy from producers. They are further divided into three groups: Herbivorous, Carnivorous and Omnivorous. Decomposers are those organism which obtain their food from dead remains of consumers and producers. They help in recycling of nutrients. The functioning of Eco-system depends on both the biotic and abiotic components.)
Lecture 2 Our Environment- II (In this lecture you will begin with Food chain. Food chain is a sequence of living organisms consumes in a community in which one organism consumes another organism to transfer food energy. It is unidirectional i.e., transfer off energy takes place only in one direction. In aquatic ecosystem, the food chain starts with microscopic free floating plants( phytoplankton). Food web is an interconnected food chains operating in an ecosystem which establish a relationship between various species. The various levels of food chain at which transfer of food takes place is called trophic level. Then we have some human activities that largely affect the ecosystem which has lead to ozone layer depletion. Ozone is a gas that surrounds the earth to stop the harmful UV rays entering the earth. At the end you will learn the management of Garbage we produce.)
