Assertion : Insects visit flower to gather honey. Reason : Attraction of flowers prevents the insects from damaging other parts of the plant
1 Both assertion and reason are true and reason is the correct explanation of assertion
2 Both assertion and reason are true but reason is not correct explanation of assertion
3 Assertion is true but reason is false
4 Both assertion and reason are false
Explanation:
D Attraction to flower cant prevent the insects from damaging other parts as only those insects are attracted to the flowers, which help in pollination not gather honey, such as bees, moth etc. Nectar and pollen grains are the usual floral rewards provided by the flower to the insect and the body of the animal get a coating of pollen grain which are generally sticky in animal pollinated flowers. These pollen grains are burst of when the insect body comes in contact with a receptive stigma. Thus, both assertion \& reason are false.

The flower shown in the adjacent diagram is :
1 Homochlamydeous unisexual and hypogynous
2 Homochlamydeous bisexual and epigynous
3 Dichlamydeous bisexual and hypogynous
4 Heterochlamydeous bisexual and epigynous
Explanation:
C The flower shown in the diagram has two whorls of perianth, when the calyx and corolla are distinct the condition is called dichlamydeous. It is bisexual because both sex organs ( stamens and ovary) are present together and hypogynous because ovary is superior.

Assertion (A) : Pollen banks can be used in crop breeding programs. Reason (R) : pollen grains can be stored for Many years in liquid nitrogen.
1 \(\mathrm{A}\) and \(\mathrm{R}\) are true and ' \(\mathrm{R}\) ' is the correct explanation to ' \(\mathrm{A}\)
2 \(\mathrm{A}\) and \(\mathrm{R}\) are true but 'R' is not the correct explanation to 'A'
3 A is true but \(\mathrm{R}\) is false
4 A is false but \(\mathrm{R}\) is ture
Explanation:
A Pollen banks can be used in crop breeding programmes, similar to seed banks. It is possible to store pollen grains of a large number of species for many years in liquid nitrogen \(\left(-196^{\circ} \mathrm{C}\right)\) for maintain viability of pollen. The period for which pollen grain remains highly viable depends on prevailing temperature and humidity.

4 Both (a) and (b)
Explanation:
D The floral parts are arises at the same point of ovary is called perigynous flower and ovary is semisuperior or semi-inferior. Ex - Peech, Rose, plum etc. - Epigynous flowers are having floral parts (such as the petals and stamens) attached to or near the upper part of the ovary, as in the flower of the apple, cucumber, and guava, the ovary is inferior. - In hypogynous flowers, the perianth and stamen are attached to the receptacle below the gynoecium. The ovary is superior hypogynous flowers are found in tomato, tulip.
