Cell-city analogy In a far away city, called Grant, the main export and production product is the steel widget. Everyone in the city has something to do with steel widget making, and the entire city is designed to build and export widgets. The town hall has the instructions for widget making. Widgets come in all shapes and sizes and any citizen of Grant can get the instruction and begin making their own widgets. Widgets are generally produced in the small shop around the city, and these small shops can be built by the carpenter's union (whose headquarters are in town hall). After the widget is constructed, they are placed on special carts which can deliver the widget anywhere in the city. In order for a widget to be exported, the carts take the widget to the postal office, where the widgets are packaged and labelled for export. Sometimes widgets do not turn out right, and the ‘rejects are sent to the scrap yard where they are broken down for parts or destroyed altogether. The town powers the widget shops and carts from a hydraulic dam in the city. The entire city is enclosed by a large wooden fence. Only the postal trucks (and citizens with proper passports) are allowed outside the city. Match the parts of the city printed in bold with the parts of the cell: (a) Mitochondria ________________ (b) Ribosomes ________________ (c) Nucleus ________________ (d) Endoplasmic reticulum _________________ (e) Golgi apparatus _____________ (f) Protein ______________ (g) Cell membrane ________________ (h) Lysosomes ________________ (i) Nucleolus _______________

  • Read the following statements and find out the incorrect statements. a. Ultimately all the food that is respired for life processes comes from photosynthesis. b. The energy released by oxidation in respiration is directly used for the life processes. c. The carbon skeleton produced during respiration is used as precursors for biosynthesis of other molecules in cell. d. Plants, unlike animals, have no specialised organs for gaseous exchange but they have stomata and lenticels for this purpose. e. During oxidation within a cell, all the energy contained in respiratory substrates is released free into the cell in a single step, which is trapped as chemical energy in the form of ATP.

    Water and dissolved minerals get into the root hair of a plant by a process called A and enter the conducting tissue B. The C helps the water and dissolved minerals to move up through the tissue B in roots and stem, and reach the leaves of a plant. In the leaves food is made by a process D. This food is then transported to all the parts of a plant through tissue E. The process of distributing food made in the leaves to all the parts of the plant is called F. (a) What are (i) A (ii) B (iii) C (iv) E, and (iv) F ? (b) Which tissue is made up of living cells : B or E ? (c) Name one substance (other than oxygen) which is transported by tissue A in the human body. (d) Which two components of tissue A are the cells without nucleus ? (e) Name any two organisms (animals) which do not have liquid like A in their body.

    The liquid connective tissue A circulates in our body continuously without stopping. This tissue contains a pigment B which imparts it a colour C. The tissue A consists of four components D, E, F and G. The component D fights infection and protects us from diseases. The component E helps in the clotting of tissue A if a person gets a cut. The component F is a liquid which consists mainly of water with many substances dissolved in it and component G carries oxygen from the lungs to all the parts of the body. (a) What is (i) tissue A (ii) pigment B, and (iii) colour C ? (b) Name (i) D (ii) E (iii) F, and (iv) G. (c) Name one substance (other than oxygen) which is transported by tissue A in the human body (d) Which two components of tissue A are the cell without nucleus ? (e) Name any two organism (animals) which do not have liquid like A in their body.

    Following reactions are known as inverse beta decay p+vecvrarrn+e^(+) n+vrarrp+e^(-) These reactions have extremely low probabilities. Because of this, neutrinos and antineutrinos are able to pass through vast amount of matter without any interaction. In an experiment to detect neutrinos, large number of neutrinos coming out from beta decays of a radioactive material were made to pass through a tank of water, containing a cadmium compound in solution, which provided the protons to interact with antineutrinos, which provided the protons to interact with antineutrinos. Immediately after a proton absorbed a neutrino to yield a positron and a neutron, the positron encountered an electron and both got annihilated. the gamma ray detectors surrounding the tanks responded to the resulting photons. This confirmed that the above reaction has taken place. (a) How many gamma ray photons are produced when a electron annihilates with a positron? What is energy of each photon? Take the mass of an electron to be 0.00055 u. (b) The neutron produced in the above reaction was captured by .^(112)Cd to form .^(113)Cd . The atomic masses of these two isotopes of cadmium are are 111.9028u and 112.9044u respectively. mass of a neutron is 1.0087u. find the Q value of this reaction. Assume half of this energy is excitation energ of .^(113)Cd . if the nucleus de-excites by emitting a gamma ray photon find its wavelenght.
