Eukaryotic Cell

  • The cells which contain true nuclei are called eukaryotic cells.
  • Eukaryotic cells are found in animals, plants, algae and fungi.
  • They are larger in size as compared to prokaryotic cells.
  • The cells may vary in shape, size and physiology but they all have a typical structure with little variations in number and location of cellular organelles.
  • The eukaryotic cell have a outer covering membrane called plasma membrane / cell membrane.
  • Inside the cell a membrane-bound nucleus is present.
  • Between the nucleus and plasma membrane, cytoplasm is present in which various cellular organelles like mitochondria, golgi complex, centrioles etc can be seen.
✱ Shape:
  • Eukaryotic cells exhibit diversity.
  • They can be spherical, triangular, tubular, cuboidal, polygonal, cylindrical, oval, rounded or elongated.
  • Shape of cells may vary from organ to organ.
  • A single organ may show variations in shape of cell.
✱ Size:
  • Eukaryotic cells are microscopic.
  • They are larger in size as compared to prokaryotic cells.
  • They size range from 0.001 mm to 175 mm.
  • Ostrich egg cell is largest cell, about 175mm in diameter.
  • Nerve cells may reach up to the length of 3 to 3.5 feet.

From the following statements,                                                                                         (DEC 2016) a) Hydrogen, Deuterium and Tritium differ in the number of protons. b) Hydrogen, Deuterium and Tritium differ in the number of neutrons. c) Both Deuterium and Tritium are radioactive and decay to hydrogen and deuterium respectively. d) Tritium is radioactive and decays to helium. e) Carbon-14 decays to Nitrogen-14. f) Carbon-14 decays to Carbon-13. Pick the combination with all correct statements. A) a, b and f      B) b, d and e C) a, c and d      D) c, e and f Ans. B - b, d and e Explanation: Hydrogen, deuterium and tritium are isotopes. Isotopes differ in the number of neutrons  and hence statement "b" is correct. Deuterium is non-radioactive but tritium is radioactive. Tritium shows β decay and tritium dec

1.     Heredity and Evolution Introduction: Basic unit of life is cell. Controlling center of cell is nucleus. Inside nucleus there are chromosomes. Chromosomes are made up of DNA. Segment of DNA is called as gene. ✱ Heredity and Hereditary Changes: Heredity: Transfer of characters from one generation to another via genes. Johann Gregor Mendel - Father of modern genetics. Hugo de Vries - Mutation Theory (1901). Walter and Sutton - Observed paired chromosomes in cells of grasshopper. Ostwald Avery, Maclyn McCarthy and Colin MacLeod - Except viruses, all living organisms have DNA as genetic material (1944). Francois Jacob and Jack Monad - Proposed a model for process of protein synthesis. Science of heredity is useful for: Diagnosis, treatment and prevention of hereditary disorders. Production of hybrid varieties of animals and plants. In industrial processes in which microbes are used. ✱ Structure of DNA (Deoxyribo Nucleic Acid) Chromosomes are made up of DNA. Chromosomes are always in

 KINGDOM PROTISTA PHYLUM - PROTOZOA The name Protozoa (Protos = first, zoon = animal) comes from Goldfuss(1818) who, however used the names simply for the lower groups of zoophyta including protozoans, sponges, coelentrates, rotifers, and bryozoans. It was von  Siebold (1845) who, recognised the unicellular nature of Protozoa, first used and defined the name Protozoa in the present sense. The study of Protozoa is known as Protozoology. Characteristics of Protozoa: These are microscopic and colourless organisms. They are terrestrial or aquatic, free living or parasitic. Body exhibit radial or bilateral, spherical or irregular symmetry. Body is naked consisting of uninucleated or multinucleated protoplasm. Body is bound by a delicate membrane or a firm pellicle, theca or lorica or siliceous shell. Locomotion occurs by pseudopodia or cilia or flagella. They are holozoic or saprozoic (feeding on dead organic matter) or holophytic in nutrition. Digestion is intracellular and reserve food is
