           PLANT KINGDOM

In the biological classification we looked at the broad classification of living organisms under the system proposed by Whittaker 1969.

Which suggested the five kingdom. 

• algae ,bryophytes, pteridophytes ,gymnosperms and angiosperms under plantae.

✓ gross superficial morphological based mananiy on vegetative characters on the the roecium structure system given by Linnaeus such system are artificial. 


✓ artificial system are gave equal weightages to vegetative and sexual characteristics this is not capable since we know that often the vegetative characters are more easily affected by environments.


✓  external features but also internal features like ultra structure anatomy embryology and phytochemistry such as classification for flowering plants was given by George Bentham and Joseph delton hooker.


✓ phylogenetic classification system based on evolutionary relationship.

✓ same taxa having a common and ancestors.

✓ Numerical taxonomy which is number and course are assigned to all the characters and the data.

✓ cytotaxonomy is based on the site or logical information like the chromosome number structure behaviour.

✓ chemo taxonomy that uses the chemical constituents of the plants.

Herbicides Important Topics

By -
 Herbicides :-  Chemical method of meet control is very effective in certain cases and use great score provided the herbicides are cheap efficient and easily available.  The chemical used for killing weeds or inhibiting the growth of weights are called herbicides Classification of Herbicides :-   Based on Method of application :-  i) Soil applied herbicides: Herbicide act through root and other underground parts of weeds.e.g. Fluchloralin ii) Foliage applied herbicides : Herbicide primarily active on the plant foliage e.g.Glyphosate, Paraquat. Based on Mode of action :-  i) Selective herbicide: A herbicide is considered as selective when in a mixed growth of plant species, it kills some species without injuring the others.e.g. Atrazine ii) Non-selective herbicide: It destroys majority of treated vegetatione.g. Paraquat Based on mobility :-  i) Contact herbicide: A contact herbicide kills those plant parts with which it comes in direct contact e.g...

Computer Memory by Grovestudies

 GroveStudies Production: Computer Memory The computer memory holds the data and instructions needed to process raw data and produce output. The computer memory is divided into large number of small parts known as cells. Each cell has a unique address which varies from 0 to memory size minus one. Computer memory is of two types: Volatile (RAM) and Non-volatile (ROM). The secondary memory (hard disk) is referred as storage not memory. But, if we categorize memory on behalf of space or location, it is of four types: Register memory Cache memory Primary memory Secondary memory Register Memory Register memory is the smallest and fastest memory in a computer.A register temporarily holds frequently used data, instructions, and memory address that are to be used by CPU. They hold instructions that are currently processed by the CPU. All data is required to pass through registers before it can be processed. So, they are used by CPU to process the data entered by the users. Registers hold a...

Scope of Biochemistry

By -

Neuberg introduced the term biochemistry in 1903. The early part of 20th century witnessed a  sudden outburst of knowledge in chemical analysis, separation methods, electronic instrumentation for biological studies (X-ray diffraction, electron microscope, etc) which ultimately resulted in understanding the structure and function of several key molecules involved in life processes such as proteins, enzymes, DNA and RNA . Scope of Biochemistry   1) To evaluate ( मूल्यांकन करना )  nutritive value of cereals, pulses, oilseed, fruits and vegetable. 2) Formulation of balanced diet. 3) Removal and inactivation of toxic or anti nutritional factors present in food grains in general and grain legumes in particular by breeding and chemical treatments. e .g. ODAP in Keshari dal, Trypsin inhibitors. 4) Development and exploitation of better genotypes.   5) Food preservation and processing technology and post-harvest physiology of fruit crops and vegetables and their nutrit...
