Question

(a) Mention any three advantages of ausing vegetative propagation for growing some types of plants . (b) What are analogous organs?

Answer 1

same function but different structure is called
analogous...

Answer 2

(a) Advantages of vegetative propagation
1.For propagation of plants that produce little or no viable seeds
2.Many fruits are cross pollinated, so to provide consistent quality without variation vegetative propagation is preferred
3.Most often easier, rapid and more economical method
4.Flowering period is short compared to seed propagated plants
5.Method of choice in propagating plants in unfavourable environmental condition
6.Method of choice for plants to be grown in orchards and gardens due to its small size
7.Qualities of two plants can be successfully combined to form a superior hybrid plant in vegetative propagation.
(b)Analogous organs are the opposite of homologous organs, which have similar functions but different origins. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently in each lineage separately after diverging from an ancestor without wings.
