In this article,we will see in detail about the topic 'living world' beyond NCERT limits.To read the brief notes on NCERT limits,click on the above mentioned links

•Growth

 can be of two types

  1. Intussusception-addition of materials inside the body
  2. Accretion-addition of materials on the outside
Substances added can also be of two types
  1. Protoplasmic substances-components of living matter
  2. Apoplamic substances-non living materials
Growth cannot be a defining character for living

•Metabolism

can be of two types
  1. Catabolism-breaking down,release energy Eg:Respiration
  2. Anabolism-building up,consume energy Eg:Photosynthesis
Metabolism can be considered as a defining character
 

Some important binomial names

  1. Allium cepa - Onion
  2. Triticum aestivum- Wheat
  3. Solanum melongena- Brinjal
  4. Rosa indica- Rose
  5. Columba livia- Pigeon
  6. Panthera leo- Lion
  7. Canis familiaris- Dog
Short notes:
  • Taxonomy is coined by De candolle
  • Linnaeus-Father of taxonomy,gave artificial system of classification,gave hierarchical system
  • Taxonomical hierarchy = Linnaean hierarchy
  • Theophrastus-Father of Botany and Ecology,first found Botanical gardens
  • H Santapau-Father of Indian systematic botany(Taxonomy)
  • Some hybrids which includes both sterile and fertile ones
  1. Mule(sterile)-Female horse and Male donkey
  2. Hinny(sterile)-Male horse and female donkey
  3. Tigon(fertile)-Male tiger and female lion
  4. Liger(fertile)-Male lion and female tiger
  • Herbarium sheets are sprayed with insecticides like naphthalene and camphor and fungicides like 0.1% mercurric chloride

Get a grip on NEET physics for 2k18: Feeling worried in solving physics? Struggling to get above 50% in physics? Then watch this out and it may help you about the important lessons which you must focus at the eleventh hour to get above 50% in physics Click here to see   How to study physics ? First see the last year paper analysis by Resonance institute From above analysis and based on expectations I will suggest some lessons which you must be thorough with previous year questions and all formulae related to it in your fingertips which will award you above 50% in physics Just have a look at those lessons 1.Heat and thermodynamics: This lesson had 5 questions in 2017 NEET and average of 4 questions in both phases of 2016 The great advantage in these lessons(Thermodynamics and Heat transfer) is much of these can be linked to Chemistry section and can be learnt easily 2.Modern Physics: This section includes  Electromagnetic waves Semiconductors ...

Important notes on Preparation and Properties of K 2 Cr 2 O 7 In this article we are providing the keynotes to cover the one of the important compounds from the topic: Properties of D and F block elements in just 10 points. In the previous article we discussed about the Physical properties of D-block elements (A) Potassium dichromate (K 2 Cr 2 O 7 ):  1. It is an inorganic chemical reagent and is used as an oxidizing agent in various health and industry-related problems (mainly used to oxidize alcohols 2. It is acutely and chronically harmful to health. 3. It is a crystalline ionic solid with a very bright, red-orange color and is moderately soluble in cold water but freely soluble in hot water. 4. It has a triclinic geometry with a tetrahedral coordination geometry. 5. Preparation: It is prepared from chromite ore (FeCr2O4). This preparation involves many steps: i. Preparation of Sodium Chromate Chromite ore is finely powdered and is he...

Important Chapters in Biology for NEET 2018 (Chapter-wise weightage) As we all know, NEET is one of the toughest examination after AIIMS for admission to MBBS Course all over India. One way to excel in NEET is to have the best study plan which we have already shared. Apart from this, access to best books along with top mentors can help you to shine with good rank in NEET. But above all these, mentally equipping yourself about the exam is important. This includes information about Syllabus and respective chapter wise weight age.In this article, we will discuss individual chapter wise weight age of BIOLOGY unit. The weight age given in the article is calculated by detailed analysis of last three year NEET Paper. So, it represents average weight age pattern for NEET Exam. Unit Wise Weightage Biology consists of 10 Units covering different chapters from Class XI and Class XII. Looking at the Pie Diagram given below, it can be inferred that Human Physiology (16.3%) followed by...

Hi guys,let's continue.If you have not read the Part 1  click here to read Part 1 To see the NCERT book , click here to view NCERT book for this lesson Taxonomic categories:  The category is a part of overall taxonomic arrangement and it is called the taxonomic category and all categories together constitute the taxonomic hierarchy. Each category, referred to as a unit of classification, in fact, represents a rank and is commonly termed as taxon (pl.: taxa). Remember, groups represent category. Category further denotes rank. Each rank or taxon, in fact, represents a unit of classification. These taxonomic groups/ categories are distinct biological entities and not merely morphological aggregates. The taxonomic categories are This can be remembered with the clue ' King Play Cards on Flat Green Stool  ' The points you must remember are from species to kingdom(ascending order)- specificity/common character decreases from species to kingdom(ascending or...
