Class 10 Science Chapter 5 Important Topics

1. Making order out if Chaos – Early Attempts at te Classification of Elements
–  Döbereiner’s Triads
–  Newlands’ Law of Octaves
2. Making order out if Chaos – Mendeléev Periodic Table
–  Achievements of Mendeléev’s Periodic Table
–  Limitations of Mendeléev’s Classification
3. Making order out if Chaos – The Modern Periodic Table

Summary Chapter 5 Class 10 Science

  • Elements are classified on the basis of similarities in their properties.
  • Döbereiner grouped the elements into triads and Newlands gave the Law of Octaves.
  • Mendeléev arranged the elements in increasing order of their atomic masses and according to their chemical properties.
  • Mendeléev even predicted the existence of some yet to be discovered elements on the basis of gaps in his Periodic Table.
  • Anomalies in arrangement of elements based on increasing atomic mass could be removed when the elements were arranged in order of increasing atomic number,
  • fundamental property of the element discovered by Moseley.
  • Elements in the Modern Periodic Table are arranged in 18 vertical columns called groups and 7 horizontal rows called periods.
  • Elements thus arranged show periodicity of properties including atomic size, valency or combining capacity and metallic and non-metallic character.

6. Evolution should not be Equated with ‘progress’
–  Human Evolution

Summary Chapter 9 Class 10 Science

  • Variations arising during the process of reproduction can be inherited.
  • These variations may lead to increased survival of the individuals.
  • Sexually reproducing individuals have two copies of genes for the same trait. If the copies are not identical, the trait that gets expressed is called the dominant trait and the other is called the recessive trait.
  • Traits in one individual may be inherited separately, giving rise to new combinations of traits in the offspring of sexual reproduction.
  • Sex is determined by different factors in various species. In human beings, the sex of the child depends on whether the paternal chromosome is X (for girls) or Y (for boys).
  • Variations in the species may confer survival advantages or merely contribute to the genetic drift.
  • Changes in the non-reproductive tissues caused by environmental factors are not inheritable.
  • Speciation may take place when variation is combined with geographical isolation.
  • Evolutionary relationships are traced in the classification of organisms.
  • Tracing common ancestors back in time leads us to the idea that at some point of time, non-living material must have given rise to life.
  • Evolution can be worked out by the study of not just living species, but also fossils.
  • Complex organs may have evolved because of the survival advantage of even the intermediate stages.
  • Organs or features may be adapted to new functions during the course of evolution. For example, feathers are thought to have been initially evolved for warmth and later adapted for flight.
  • Evolution cannot be said to ‘progress’ from ‘lower’ forms to ‘higher’ forms. Rather, evolution seems to have given rise to more complex body designs even while the simpler body designs continue to flourish.
  • Study of the evolution of human beings indicates that all of us belong to a single species that evolved in Africa and spread across the world in stages.

Summary Chapter 6 Class 10 Science

  • Movement of various types can be taken as an indication of life.
  • Maintenance of life requires processes like nutrition, respiration, transport of materials within the body and excretion of waste products.
  • Autotrophic nutrition involves the intake of simple inorganic materials from the environment and using an external energy source like the Sun to synthesise complex high-energy organic material.
  • Heterotrophic nutrition involves the intake of complex material prepared by other organisms.
  • In human beings, the food eaten is broken down by various steps along the alimentary canal and the digested food is absorbed in the small intestine to be sent to all cells in the body.
  • During the process of respiration, organic compounds such as glucose are broken down to provide energy in the form of ATP. ATP is used to provide energy for other reactions in the cell.
  • Respiration may be aerobic or anaerobic. Aerobic respiration makes more energy available to the organism.
  • In human beings, the transport of materials such as oxygen, carbon dioxide, food and excretory products is a function of the circulatory system. The circulatory system consists of the heart, blood and blood vessels.
  • In highly differentiated plants, transport of water, minerals, food and other materials is a function of the vascular tissue which consists of xylem and phloem.
  • In human beings, excretory products in the form of soluble nitrogen compounds are removed by the nephrons in the kidneys.
  • Plants use a variety of techniques to get rid of waste material. For example, waste material may be stored in the cell-vacuoles or as gum and resin, removed in the falling leaves, or excreted into the surrounding soil.

Summary Chapter 8 Class 10 Science

  • Reproduction, unlike other life processes, is not essential to maintain the life of an individual organism.
  • Reproduction involves creation of a DNA copy and additional cellular apparatus by the cell involved in the process.
  • Various organisms use different modes of reproduction depending on their body design.
  • In fission, many bacteria and protozoa simply divide into two or more daughter cells.
  • Organisms such as hydra can regenerate if they are broken into pieces. They can also give out buds that mature into new individuals.
  • Roots, stems and leaves of some plants develop into new plants through vegetative propagation.
  • These are examples of asexual reproduction where new generations are created from a single individual.
  • Sexual reproduction involves two individuals for the creation of a new individual.
  • DNA copying mechanisms create variations which are useful for ensuring the survival of the species. Modes of sexual reproduction allow for greater variation to be generated.
  • Reproduction in flowering plants involves the transfer of pollen grains from the anther to the stigma which is referred to as pollination. This is followed by fertilisation.
  • Changes in the body at puberty, such as increase in breast size in girls and new facial hair growth in boys, are signs of sexual maturation.
  • The male reproductive system in human beings consists of testes that produce sperms, vas deferens, seminal vesicles, prostate gland, urethra and pen!s.
  • The female reproductive system in human beings consists of ovaries, fallopian tubes, uterus and vag!na.
  • Sexual reproduction in human beings involves the introduction of sperm in the vag!na of the female. Fertilisation occurs in the fallopian tube.
  • Contraception to avoid pregnancy can be achieved by the use of condoms, oral pills, copper-T and other methods.

–  Color of the Sun at Sunrise and Sunset

Summary Chapter 11 Class 10 Science

  • The ability of the eye to focus on both near and distant objects, by adjusting its focal length, is called the accommodation of the eye.
  • The smallest distance, at which the eye can see objects clearly without strain, is called the near point of the eye or the least distance of distinct vision. For a young adult with normal vision, it is about 25 cm.
  • The common refractive defects of vision include myopia, hypermetropia and presbyopia. Myopia (short-sightedness – the image of distant objects is focused before the retina) is corrected by using a concave lens of suitable power. Hypermetropia (far-sightedness – the image of nearby objects is focused beyond the retina) is corrected by using a convex lens of suitable power. The eye loses its power of accommodation at old age.
  • The splitting of white light into its component colors is called dispersion.
  • Scattering of light causes the blue color of sky and the reddening of the Sun at sunrise and sunset.
