Study of Stomatal Distribution on Leaves

Stomata are minute pores found on the epidermis of leaves and young shoots of plants that are used to control exchange of gases. The pore is surrounded by a pair of specialised cells called the guard cells that are responsible in regulating the size of the opening. Distribution of stomata varies between monocots and dicots, between plant species, and between the underside and top side of the leaves on a plant. Stomata are found more on plant surfaces thriving under higher light, lower atmospheric carbon dioxide concentrations and in moist environments. Usually the lower surface of a dicot leaf has…

Screw Gauge

The screw gauge is an instrument used for measuring accurately the diameter of a thin wire or the thickness of a sheet of metal. It consists of a U-shaped frame fitted with a screwed spindle which is attached to a thimble. The pitch of the screw is the distance moved by the spindle per revolution. To find this, the distance advanced by the head scale over the pitch scale for a definite number of complete rotation of the screw is determined.   This video explains how to find the volume of a wire and an irregular lamina along with the…

Metre bridge-Resistance of a wire

The metre bridge is operates under Wheatstone’s principle. Here, four resistors P, Q, R, and S are connected to form the network ABCD. The terminals A and C are connected to a battery, and the terminals C and D are connected to a galvanometer through keys K1 and K2 respectively. In the balancing condition, there is no deflection on the galvanometer. Then, P/Q = R/S.   This video explains how to find the resistance of a given wire using a metre bridge and hence determine the specific resistance of its materials.  

Determination of Concentration of KMnO4 Solution Using Oxalic Acid

The oxidation and reduction reactions in aqueous solutions involve the transfer of electrons from one species to another. In the oxidation of a substance electron(s) is (are) transferred from the species and in reduction, electron(s) is (are) gained by the species. Oxidation and reduction reactions occur simultaneously. A reaction, which involves simultaneous oxidation and reduction, is called a redox reaction. The titrations involving redox reaction are called redox titrations. In Redox titrations involving potassium permanganate, it acts as a powerful oxidising agent.   This video explains how to determine the strength of potassium permanganate solution by titrating it against a…

Asexual Reproduction in Amoeba and Yeast

The type of reproduction that takes place without the process of gamete (sex cell) formation is called asexual reproduction. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea, bacteria, and protists. Many plants and fungi reproduce asexually as well. Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only. The offspring will be the exact genetic copies of the parent. Binary fission and budding are two common method of asexual reproduction. Binary fission is found in unicellular organisms like Amoeba, Paramaecium…

Onion and Cheek Cells

The cell is possibly the most important concept in biology since it is the basic unit of life. Every living organism is made up of cells (or just one in the case of bacteria). All the animals, trees and plants are made up of cells that share many similar characteristics.   An onion is a multicellular (consisting of many cells) plant organism.As in all plant cells, the cell of an onion peel consists of a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. The presence of a cell wall and a large vacuole are indicators that help identify…

Vernier Calipers

The modern Vernier caliper was invented by Joseph R. Brown in 1851. It was the first practical tool for exact measurements that could be sold at an affordable price to ordinary machinists. The Vernier Caliper consists of a main scale fitted with a jaw at one end. Another jaw, containing the vernier scale, moves over the main scale. When the two jaws are in contact, the zero of the main scale and the zero of the Vernier scale should coincide. If both the zeros do not coincide, there will be a positive or negative zero error.   This video explains…

Determination of Concentration of KMnO4 Solution using Ferrous Ammonium Sulphate

Titration is a common laboratory method of qualitative chemical analysis that can be used to determine the unknown concentration of a solution (analyte). The basis of this process is the reaction between the analyte and a solution of unknown concentration (standard solution). The titration based on oxidation and reduction reaction between the titrant and analyte is called Redox titration. Oxidation is the process of the addition of oxygen or removal of hydrogen/electron and reduction involves the process of addition of hydrogen/electrons or removal of oxygen. In redox systems, the titration method can be adopted to determine the strength of a…

Spherometer

Sphero Meters are small precision instruments for measuring the radius of curvature of spherical surfaces. They can also be used to measure the thickness of a thin plate. A spherometer works on the principle of the micrometer screw. Spherometer consists of a metallic tripod framework supported on three fixed legs of equal lengths. A screw passes through the centre of the tripod frame, parallel to the three legs. A large circular disc graduated with 100 equal parts is attached to the top of the screw. A small vertical scale known as the Pitch scale (P) with the scale reading divided…

Happy Engineer’s Day 2017: Remembering Sir M Visvesvarayya

The nation will on Friday celebrate Engineer’s Day to mark the 156th birth anniversary of Sir Mokshagundam Visvesvarayya, one of the greatest engineers India has produced and a person behind many iconic constructions in India. Year 2017 will mark the 49th anniversary of the Engineers Day in India. It is a significant occation considering the fact that India produces close to 20 lakh engineers in a year.   Who was Sir Visvesvarayya? Sir Visvesvarayya was an acclaimed engineer recognized for his mastermind in harnessing water resources. He had successfully designed and constructed several river dams, bridges and revolutionized the irrigation…

Lack Of Job Opportunities Behind Fall In Engineering Admissions: AICTE Chairman

Bhubaneswar: Chairman of All India Council for Technical Education  (AICTE) Anil Sahasrabudhe, while attending an event in Bhubaneswar today, said lack of job opportunities is responsible for the fall in admissions into engineering courses.   Talking to OTV Sahasrabudhe said, “As the large scale industries, especially the multinationals, are not increasing the jobs rather decreasing, a student gets disheartened without a job offer after completing four years of education.”   The second problem which is not apparent is that a number of private and deemed universities have come up that are also providing engineering courses. So it is not that…
