1. In what ways is vegetative propagation better than sexual reproduction? 2. Describe parts of flower in brief? 3. How is self pollination different from cross pollination? 4. How are fruits formed? 5. Why is dispersal of seed necessary for growth of plants?
Answers
Answer:
2.ans :- most flowers have 4 main parts.
sepals, petals, stamens, and carpels.stamen has the male part where as carpels is the female parts of the flower. most of the flowers are the hermaphrodite they contain both..male and female....
1.ans:- because....this methode takes less tym for growth. in this methode ....some plants are copies there parent but some plants which don't produce viable seeds can be produce by this methode.
3.ans:- self pollination, the pollens from the anthers of a flower are transferred to the stigma of the same flower, eg: wheat, rice, pea...etc
cross pollination, it involves the transfer of pollen grains from the anther of one plant to the stigma of another plant. this is only type of pollination which brings genetically different types of pollen grains to the stigma during pollination, eg: papaya, maize... etc
4.ans:- fruits are produced only by flowering plant (angiosperm ) following the pollination of the flower the fertilized ovules develope into seed while the surrounding ovary wall form the fruit tissue or pericarp.
5.ans:- dispersal of seed is very important or the survival of plants species.if plant too grow closely together , they have complete for light , water and nutrients from the soil. seed dispersal allow plants to sperad out from a wide area and avoid competing with one another for the same resources....
