Make a list of any three outbreeding devices that flowering plants have developed and explain how they help to encourage cross pollination.

Describe how different agents help in cross pollination.

Discuss the important outbreeding devices for cross pollination?

Geitonogamous flowering plants are genetically autogamous but functionally cross pollinated. Justify.

Flowering plants have developed certain outbredding devices to discourage self-pollination and encourage cross-pollination. One of these is not an examples of such outbreeding device.

Give any three characters that have developed during human evolution.

Explain the significant of pollination in flowering plants .

List any three important characteristics of a population and explain.

Consider the following statements. (i)In Gynandropsis, Passiflora , etc., thalamus is elongated and shows well developed nodes and internodes. (ii)The floral buds in Agave, Allium , etc. , may sometimes get modified into vegetative buds or bulbils. (iii)Sepals are concerned with protection of flowers in bud condition and petals help to attract insects for pollination. (iv)Stamens and carpels serve as the male and female reproductive organs respectively. Which of the following combinations of above statements provides an evidence that flower is a modified shoot ?
