primitive and non primitive unit cells

Reproduction is defined as the production of individuals of the same species, that is the next generation of the species. There are basically two types of reproduction - asexual and sexual. Asexual reproduction involves only one parent and the offspring is genetically similar to the parent...

Summary - Reproduction is defined as the production of individuals of the same species, that is the next generation of the species. There are basically two types of reproduction - asexual and sexual.

. Cyanobacteria are characterised by the presence of phycocyanin (blue) and chlorophyll (green) pigments. The Kingdom Protista includes primitive unicellular eukaryotic organisms. Protista are mainly represented by unicellular algae (such as diatoms) and protozoans - rhizopods, flagellate..

Mitosis is a type of cell division that occurs in the somatic (body) cells. A diploid (2n) parent cell gives rise to two diploid (2n) daughter cells. For the purpose of description mitosis is divided into four stages: Prophase Metaphase Anaphase Telophase It ..

A first-order differential equation is said to be linear if, in it, the unknown function y and its derivative y' appear with non-negative integral index not greater than one and not as product yy' either. Hence, a first-order linear differential equation is of the form: where p and q a..

Every organism consists of parts that can be arranged in increasing levels of complexity. Each higher level is more complex than the one below it. The smallest structural unit of matter, both non-living and living are protons, neutrons and electrons. These particles combine in a..

The macromolecules found in a cell are large molecules with a complex structure and very high molecular weight. They are represented by polysaccharides, proteins and nucleic acids. Polysaccharides are polymers of monosaccharides. They are linear, branched or unbranched molecular chai..

Enzymes - Enzymes are the biocatalysts of life. They are defined as biocatalysts synthesized by living cells. They are simple or conjugate protein and specific in action. At present about 300 enzymes are recognized and classified into six classes by International Union of Biochemistry (IU..

>Monosaccharides are simplest, single sugars. Depending on the number of carbon atoms, they can be distinguished into trioses, tetroses, pentoses, hexoses, heptoses and octoses. Pentoses and hexoses are biologically significant sugars. Pentoses are essential components of nucleic acids. Hexoses lik..
