Question

methodology , observation ,inferences,conclusion of monocot and dicot plants

Answer 1

Materials RequiredOrchid PlantHibiscus PlantReal Lab ProcedureYou will need an orchid plant and a hibiscus plant that have roots, leaves and flowers.Study the venation, leaves, nature of root system, stem and flowers of both the plants.Simulator Procedure (as performed through the Online Labs)From the shown four choices select the correct plant part from the left window pane that relates to the shown plant.Drag your selected choice and place it near the plant.  If the choice is wrong the selection goes back.You can try this for different plant parts by clicking on the ‘Reset’ button.If you have any doubt, you can click on the help button that provides you with hints.Observations

Record the observations in a table.

PropertyOrchid PlantHibiscus PlantVenationOrchid has parallel venation.Hibiscus has reticulate venation.LeavesLeaves of orchid plant are sessile.Leaves of hibiscus plant have stalks.RootOrchid plant has adventitious roots.Hibiscus plant has taproots.StemOrchid has weak stem.Hibiscus has strong stem.FlowerThree petals and three sepals.Five petals and five sepals.Conclusion

From the above observation it can be concluded that the orchid is a monocot plant and the hibiscus is a dicot plant.

Answer 2

Monocot Plant

Root                                       Adventitious fibrous root

Stem                                      Hollow, weak, disc-like appearance

Leaves                                   Sessile

Venation                                Long parallel

Flower-petals                        Multiples of three

Seeds                                    Single cotyledon

Example                                Orchid flowers, maize, rice, wheat

Dicot Plant

Root                                       Taproot                              

Stem                                      Strong

Leaves                                   Has a stalk

Venation                                Branched reticulate

Flower-petals                        Multiple of four or five    

Seeds                                    Double cotyledon

Example                                Hibiscus flower, mango, groundnut, peas

Inferences: The various features of the flowering plants (angiosperms) and the difference between the dicots and monocots were noted and understood.
