6. Assertion: In fungi, vegetative reproduction occurs by fragmentation and budding.
Reason: Asexual reproduction in fungi, occurs through formation of asexual spores.

7. Assertion : Study of biology requires basic knowledge of chemistry and physics.

8. Assertion: Binomial nomenclature is system of providing name with two words.

9. Assertion: A living organism is unexceptionally differentiated from a non living structure in the basis of responsiveness.

12. The process to standardize the naming of living organisms is called nomenclature. Obviously, the nomenclature is only possible when the organism is described correctly and we know to what organism the name is attached to this is identification. The system of providing scientific name with two components is called Binomial Nomenclature. The scientific name ensures that each organism is identified by only one name all across the world. They also ensures that such a name has not been used for any other known organism. Scientific names for plants are provided in ICBN and for animals, in ICZN. Who proposed binomial nomenclature?

13. From the passage in question number 16, Which of the following is an example of binomial scientific name?

14. From the passage in question number 16, In binomial nomenclature, the name of organism consists of

16. From the passage in question number 16, In binomial nomenclature, ...............epithet starts with small letter

17. All living organisms grow. Increase in mass and increase in number are twin characteristic of growth. Multicellular organisms grow by cell division. In plants, growth occurs continuously throughout their life span. Non living organisms also grow if we take increase in body mass as criterian for growth. However, this kind of growth exhibited by non living objects is by accumulation of the material on surface. Growth, therefore cannot be taken as defining property of living organisms What are the twin characteristics of growth?
