Death - Death is the final termination of the life activities. Every living organism has a life cycle involving its birth, growth and death. The duration of life between the birth and death of an organism, represents its life span. This ranges from as little as a few minutes to as long as thousands..

Systematic Position - Kingdom : Metazoa Subkingdom: Eumetazoa Division : Bilateria Grade : Eucoelomata Phylum : Arthopoda Class : Insecta Order : Orthoptera Family : Blattidae Genus : Periplaneta Species : america..

. This produces a branching pattern of evolutionary relationships. Such evolutionary change and relationships are represented in "family trees," or 'phylogenetic' trees. The trees show the relationships among organisms illustrate the idea that all of life is related. Many of the phylogenies one enc..

. Each phylum or division has the next taxon called Class . The members of each class exhibit certain distinguishing characters that are unique only to them. In the same way, using comparable criteria of similarities and relationships, each class can be divided into orders , each order into familie..

Systematic Position - Division: Angiospermae Class: Dicotyledonae Sub Class: Polypetalae Series: Calyciflorae Order: Rosales Family: Fabaceae (=Leguminosae) Leguminosae is one of the largest families in dicots, including about 690 genera and nearly 18,000 species. In all the major systems..

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. Asexual reproduction involves only one parent and the offspring is genetically ..

Introduction - In the description of Angiosperms, family is the most useful taxonomic unit. Ranks higher than family are not of much practical significance and are used mostly in classification systems and academic discussions. The taxonomic category genus also does not get much importanc..

Evolution by Stages - The evolutionary process has developed over millions of years. Lineages evolved and split and modifications occurred gradually in stages. Life has been in existence on Earth for at least 3.5 billion years but the first two stages of evolution took place in the space of a billi..

Herbaria - A herbarium represents a collection of plant material from a given locality. The specimen is dried, and pressed between paper and cardboard sheets. The herbaria are then arranged in accordance with any accepted system of classification, for further reference and research. fig. 11.1 - Her..

Designer Plants - Many years ago, Frederick Steward and his co-workers cultured cells from carrot plants and induced some of them to develop into small embryos. Some of these embryos grew into whole plants. Today, researchers routinely regenerate crops, plants and many other plant species..
