Homeostasis is the eleventh chapter of Chemistry 10 class notes in PDF form. Homeostasis may be defined as the maintenance of the internal conditions of the body at equilibrium,
despite changes in the external environment. You can describe homeostasis in plants.
Transpiration is the loss of water from plant surfaces in the form of vapours. Plants deposit many metabolic wastes in their bodies as harmless insoluble materials. We are providing Knowledge about osmotic adjustments in plants.
Osmosis is the movement of water from hypotonic solutions to hypertonic solutions, through the semipermeable membrane. You can explain homeostasis in humans, the urinary system Of humans, and the structure of the kidney.
You can also describe the capillaries of the glomerulus that arise from the afferent arteriole and join to form the efferent
Biology 10th Class Notes Chapter 12
Coordination and Control is the twelfth chapter of Chemistry 10 class notes Punjab board. You will be able to define types of coordination. In organisms, there are two different types of coordination: i. neurological coordination caused by the nerve system, and ii. chemical coordination caused by the endocrine system.
You can also describe Coordinated Action which has five components:
You can explain Human Nervous System. The central nervous system and the peripheral nervous system make up the majority of the nervous system in humans and other higher animals.
We are providing information about nerve cells or neurons, divisions of the nervous system, and receptors in humans. Describe the location and purpose of the cerebrum, thalamus, cerebellum, medulla oblongata, hypothalamus, and pituitary gland in the human brain.
You can describe the structure of the human eye. Explain the role of the ear in the maintenance of balance, and outline the major glands of the endocrine system with names of their hormones and their functions.
Class 10th Biology Notes Chapter 13
Support and movement is the thirteenth chapter of Biology 10 class notes. You will study the human skeletal system which is primarily responsible for support and movement.
The big functions of the skeletal system are protection, support, and movement. In our body, the skeleton works very closely with the muscular system to help us move.
Animals have connective tissue in the form of cartilage and bone. The majority of connective tissues have a matrix of collagen fibers. You can explain the components of the human skeleton, types of joints, and muscles and movement.
Disorders of the skeletal system, osteoporosis is a bone disease in adults, especially in old people. It is more common in old women. Arthritis is defined as “joint inflammation”. It is also very common in old age and in women.
Chapter 14 Biology Class 10th Notes
Reproduction is the fourteenth chapter of Biology 10 class notes. You will define reproduction as the production of individuals of the same species i.e. the next generation of species, and methods of asexual reproduction
Asexual reproduction does not involve the fusion of gametes. Binary fission means “division into two”. It is the simplest and most common method of asexual reproduction. An individual can live without reproducing, but a species cannot survive without reproduction.
You can define fragmentation, spore formation, budding, parthenogenesis, and vegetative propagation. Sexual reproduction in plants, and also define the development and structure of seed. Germination of seeds of many plants is also favored by light. Light slows germination in some plants.
Sexual reproduction in animals, the sexual reproduction is based on the formation and fusion of male and female gametes. The testes’ seminiferous tubules contain cells that divide frequently through mitosis to produce a significant number of diploid spermatogonia.
10 Class Biology Notes Chapter 15
Inheritance is the fifteenth chapter of Biology 10 class notes. You will be able to define introduction to genetics, Genetics is the branch of biology wherein we examine inheritance. Inheritance refers to the transmission of characteristics from parents to offspring.
You can explain genes and chromosomes both include DNA. They include detailed guidelines for protein synthesis.DNA is the genetic material i.e. it contains the instructions to direct all the functions of cells.
Genotype and its types, the specific combination of genes in an individual is known as genotype. Only the expression of the recessive allele is suppressed by the dominant allele. Its nature is unaffected.
Mendel’s laws of inheritance, Mendel proposed that there are “special factors” in organisms, which control the expression of traits and their transmission to the next generations. You can describe Mendel’s law of independent assortment, co-dominance, and incomplete dominance.
Biology Class 10 Notes Chapter 16
Man and His Environment is the sixteenth chapter of Biology 10 class notes. You will be able to levels Of biological selection, a species is a group of organisms that can interbreed freely in nature, to produce fertile offspring.
We have studied in lower classes about the basic components of an ecosystem. Omnivores are the consumers that eat animal flesh as well as plants and plant products. Find examples of omnivores.
You can explain tertiary carnivores are not eaten by any other animals. They are also called top carnivores. The minerals, which are released by decomposers, are used as nutrients by the producers.
The flow of materials from one trophic level to the next by means of food chains and food webs e.g, producer, primary consumer, secondary consumer, the tertiary consumer.
Ecological pyramids, and biogeochemical cycles, Since the movement of elements and inorganic compounds is essential for the maintenance of life, they are also called “nutrient cycles”.
Biology Notes 10 Class Chapter 17
Biotechnology is the seventeenth chapter of Biology 10 class notes. You will explain Biotechnology as the use of living organisms in processes for the manufacture of useful products or services, and the scope and importance of biotechnology.
It has attracted the attention of many intellectuals from diverse fields like agriculture, medicine, microbiology, and organic chemistry. Describe biotechnology in the field of medicine. In the field of medicine, biotechnologists synthesized insulin and interferon from bacteria and released them for sale.
You can explain biotechnology in the field of food and agriculture. Fermented foods, malted foods various vitamins, and dairy products are produced by using microorganisms. Biotechnology Environment and fermentation is the process in which there is incomplete oxidation-reduction of glucose.
Alcoholic Fermentation (by yeast), this fermentation is carried out by many types of yeast such as Saccharomyces cerevisiae. In fact, the fermenter constitutes the heart of any industrial fermentation process.
Genetic engineering or recombinant DNA technology involves artificial synthesis, modification, removal, addition, and repair of the genetic material (DNA). The important objectives of genetic engineering are as follows.
• Isolation of a particular gene or part of a gene for various purposes such as gene therapy.
• Production of particular RNA and protein molecules.
Biology Class 10 Notes Chapter 18
Pharmacology is the eighteenth chapter of Biology 10 class notes. You will study Pharmacology as drug composition, properties, and medical applications. The sources of drugs are also studied in pharmacology.
A pharmaceutical drug, also known as a medicinal drug, is defined as any chemical substance used in the diagnosis, cure, treatment, or prevention of disease. Drugs are obtained from the following sources.
- Drugs from Plants and Fungi
- Synthetic Drugs
- Drugs from Animals
- Drugs from Bacteria
- Drugs from Minerals
Principle Usage Of Important Medicinal Drugs: Vaccines are used to develop immunity against viral and bacterial infections. Antibiotics inhibit or kill bacteria and treat bacterial infections. Sedatives work by reducing irritability or excitement. Analgesics (painkillers) reduce pain.
- Biology provides us with a better understanding of food production through plants and animals.
- Through the study of biology, we have gained an understanding of diseases, how they spread, and how to treat them.
- Biology provides us with a better understanding of genetics and how a gene affects a living organism’s characteristics.
- Biology research may be expensive.
- Biological knowledge can be used for harmful purposes.
