1. Growth

1.1. Twin characters -growth in mass and number

1.2. Non living organisms can grow -boulders &rocks

1.3. Not a defining characters of living organism

1.4. Growth and Reproduction are mutually exclusive events

2. Reproduction

2.1. Production of progeny posessing features similar to parents

2.2. Organisms doesn't reproduce Eg. Mules, sterile worker bees, infertile human being

2.3. Not a defining characteristics of living organism

3. Consciousness

3.1. Consciousness is the defining property of living organism

4. Metabolism

4.1. Sum of all chemical reaction occurring in our body is metabolism

4.2. No non living organism exhibit metabolism

4.3. Isolated metabolic reaction in in vitro are nit living things but living reaction

4.4. Cellular organisation is defining property of living organism

5. Biodiversity

5.1. The no and type of organisms present on earth

5.2. Described range 1.7-1.8 million

6. Nomenclature

6.1. A particular organism is known by the same name all over the world

6.2. Universal rules

6.2.1. Names are written in Latin and written in italics

6.2.2. First word-genus Second word-specific epithet

6.2.3. Biological names underlined when handwritten or printed in italics

6.2.4. Genus starts with caps letter Specific epithet starts with small letter

7. Binomial nomenclature

7.1. Two components Generic name Specific epithet

8. Taxonomy

8.1. The process of classification of all living organisms into different taxa.

9. Systematics

9.1. Study of organisms and their diversities and also relationship among them

9.2. Systema-systematic arrangements of organisms

10. Taxonomic categories

10.1. Species

10.1.1. Studies consider a group of individual organism and their fundamental similarities

10.1.2. Distinct morphological differencrs

10.2. Genus

10.2.1. A group of related species which has more characters in common in comparison to the species of other genera

10.3. Family

10.3.1. A group of related genera with still less no of similarities compared to genus and species

10.4. Order

10.4.1. Few similar charecters

10.5. Class

10.5.1. It includes related orders

10.6. Phylum

10.6.1. In plants it is called division

10.7. Kingdom

11. Taxonomical aids

11.1. Herbarium

11.1.1. Store collected plant specimens(dried, pressed, preserved on sheets)

11.1.2. It become a store house or repository for future use

11.1.3. Label-date and place of collection, English, local and botanical names, family, collectors name

11.2. Botanical garden

11.2.1. Living plants for references

11.2.2. Labelled-its botanical/scientific name and it's family

11.3. Museum

11.3.1. Set up in educational institutions

11.3.2. Insects-collecting, killing and pinning

11.3.3. Animals are stuffed and preserved and collection of specimens

11.4. Zoological park

11.4.1. Animals are kept in human care

11.5. Key

11.5.1. Used for identification of plants and animals based on similarities and dissimilarities

11.5.2. Based on contrasting characters generally in pair called couplet

11.5.3. Results in acceptance of one and rejection of other

11.5.4. Each statement in key is called lead

11.5.5. Analytical in nature

11.6. Flora

11.6.1. Actually account of habitat and distribution of plants of given area

11.7. Manuals

11.7.1. Information for identification of names of species found in an area

11.8. Monographs

11.8.1. Information on any one taxon

12. Human being is only one who is aware of himself ie. Self consciousness
