2. The cell is the smallest unit of life. Cell is basic structural and functional unit of living organisms. New cells arise from pre-existing cells. All organism are composed one or more cells INTRODUCTION : TOPIC DECLARATION : Today we are going to discuss about CELL THEORY

3. CELL ORGANISM STRUCTURE SINGLE-CELLED KEY WORDS : Robert Hooke was the first scientist to discover existence of cells with the help of a microscope in 1965. He observed thin slices of cork (a part bark of a tree, under a microscope and saw honey comb structures. Thus, all living things begin as individual cells. These cells multiply, divide through mitosis, and eventually form multicellular organisms. Mitosis is a type of cell division that yields identical cells. When mixed signals are applied to these cells, they can differentiate to form various tissues and organs. This is the process used to produce enormous, complex organisms. However, when a single-celled organism divides, the cells split into two new organisms. This process of reproduction is asexual. CONTENT :

4. ACTIVITY : DISCUSSION : With continual improvements made to  microscopes  over time, magnification technology became advanced enough to discover cells. This discovery is largely attributed to  Robert Hooke , and began the scientific study of cells, known as  cell biology . When observing a piece of cork under the scope, he was able to see pores. This was shocking at the time as it was believed no one else had seen these. To further support his theory,  Matthias Schleiden  and  Theodor Schwann  both also studied cells of both animal and plants. What they discovered were significant differences between the two types of cells. This put forth the idea that cells were not only fundamental to plants, but animals as well.

5. CONCLUSION : Energy flow ( metabolism  and  biochemistry ) occurs within cells. Cells contain  DNA  which is found specifically in the chromosome and  RNA  found in the cell nucleus and cytoplasm. All cells are basically the same in chemical composition in organisms of similar species. EVALUATION : All known living things are made up of one or more cells [13] All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells.

7. INTRODUCTION Good morning children Students I will ask some questions please give me the answers Do you know about Cell Membrance ? How to prepare Cell Wall? TOPIC DECLARATION Today we are going discuss about Cell Membrane

8. KEY WORDS Cell Membrane M embrane commodities Outer membrane Cytoplasm CONTENT Cell Membrane (plasma membrane) Outer membrane of cell that controls the entry and exit of substances according to the requirement of cell the

9. ACTIVITY DISCUSSION What is Cell Membrane ? What is plasma membrane ? What is Cell Wall? What is oxygen? What is diesel fuel?

10. CONCLUSION Students today we Cytoplasm We discussed about Cell Wall EVALUATION Petroleum is formed from the remains of dead plants and animals. When plants and animals die, they sink and settle on the seabed. Millions of years ago, these dead wildlife and vegetation decomposed and got mixed with sand and silt. Certain bacteria helped in the decomposition of this organic matter and caused some  chemical changes . Signature of the School Teacher Signature of the Internal

12. INTRODUCTION Greetings : Good morning children Students now I will ask some questions give answers to me Do you know what is Sound ? What are the different sounds? How to generates sounds? TOPIC DECLARATION Today we are going to discuss about the topic : Sound

13. KEY WORDS NUCLEUS DNA CHROMOSOMIES CONTENT NUCLEAR MEMBRANE • Surrounds nucleus • Made of two layers • Openings allow material to enter and leave nucleus • It is made of DNA and present

14. ACTIVITY Cell Organelles The cell organelles are: Plastids: Plastid are large organelles & DISCUSSION

15. CONCLUSION The speed at which sound waves propagate through a medium is known as the speed of sound. The speed of sound is different in different media. The speed of sound is highest in solids because the atoms in solid are highly compressed. The interaction between atoms in a particle is highly dependent on the distance between them. Higher the interaction between the atoms, the quicker the energy is transferred. As the interaction of the particles in solids is high, the speed of sound is faster than liquids and gases. The table below lists the speed of sound in different media.

17. INTRODUCTION Greetings : Good morning children Students now I will ask you some questions, answer them Do you Know what is Mitochondria? Do you observe kinetic cell Recycles ? TOPIC DECLARATION Students today we are going to discuss about- MITOCHONDRIA

18. Key words Mitochondria Mitochondria cells Endoplasimic CONTENT Mitochondria They are rod shape or spherical structures. Responsible for cellular respiration & produces energy for different activities.* So, it is called power house of cell Controls level of water and other materials in cell Recycles and decomposes proteins, fats, and carbohydrates

19. ACTIVITY DISCUSSION Today we are discussing about the Mitochondria In this lesson we discussed about different Mitochondria cells To direction of endoplasimic

20. Today we discussed about Mitochondria CONCLUSION Energy production : Mitochondria produce adenosine triphosphate (ATP), the energy currency of the cell.  Metabolic regulation : Mitochondria regulate the metabolic activity of the cell.  Cell growth : Mitochondria promote cell multiplication and cell growth.  Ion homeostasis : Mitochondria play a role in ion homeostasis.  Apoptosis : Mitochondria play a role in apoptosis and programmed cell death.  ROS production and consumption : Mitochondria play a role in ROS production and consumption.  EVALUATION Signature of the School Teacher Signature of the Internal

24. CONTENT Any material that is composed of only one type of atom is called a  chemical element, a basic element, or just an element. Any material that is composed of more than one type of atom is called a  compound Every element has a unique atomic structure. Scientists know of only about 109 basic elements at this time. (This number has a habit of changing.) All matter is composed of combinations of one or more of these elements Ninety-one of these basic elements occur naturally on or in the Earth. The other elements are man-made. You may recognize the names of some of these basic elements such as: hydrogen, helium, oxygen, iron, copper, gold, aluminum, uranium. The  periodic table of elements lists the basic elements  and some of their properties. The periodic table is organized based on the  atomic number of each element, which is located in the top left corner of each element box in the table below. The atomic number is the number of protons in the nucleus of an atom of that element. The  atomic mass  is also listed for each element below under its name.  The periodic table also tells us about the state of matter each element is in at room temperature. While most elements are solids at room temperature, 11 elements , including Hydrogen, Helium, and Oxygen, are gases at room temperature and 2 are liquids.
