HELLO GUYS!!!!!
                                    How are you??? 
   I hope you are reading my blogs. In my blogs you will come to know about the plants and there structures. In my last secession i discuss about the classification of plants.You can clearly see the difference and also understand that which one is advance and which one is not. 

Hello readers!
i hope you are reading my blogs and like it very much. in my last blog i discuss about the plants structural modifications.
these adaptations are due to environmental changes and locality. the plants that are living in the high temperature(desert) are totally different from the plants that live in the low temperature(hilly areas).
i mean to say that there temprature, nutritional and many other requirements are different from each others.

DESERT PLANTS
desert plants have thick waxy layer that protect them and also prevent the water loss. they are succulent       ( plants that store water). they have small or no leaves. there stem is photosynthetic. stomata number is reduced. cactus is example

                                                                           cactus
PLANTS IN HILLY AREAS
  these plants have less waxy layer as compaired to the plants that are present in the desert. they do not face the drought condition and easily get the maximum water supply. pinus is example.

   

pinus

hello guys!

As we know that every new thing is made by the modification of the older ones. this condition also applies in the case of plants. the plants which were present in the older age / time are less modified and had less ability to cope with the harsh environmental conditions. there leaf, stems, and rhizoides ( root like structures work exactly the roots) are totally different from the plants that exist today. they have nodes and internodes. like psilotum, equsitum etc

                                  Equisetum

Then little modification occurs and the leaves become broad stem soft but rhizoides also exists. they are ferns, or may form a cushion like structure where it is difficult to distinguish between true stem leaf and rhizoide is the mosses.
               
 Fern                                                                    Moss

Then again due to little change roots developed and bark formation occurs. they are gymnosperms. they are pinus, cycus, thuja etc
                                 

                                                     cycas
 But today existing plant which are dominating on the earth are the Angiosperms. They produce flowers and due to the production of flower they produce  fruit and seeds they are more adapted to the environment.

                              

                                           Angiospems 

                                                   

   

           

                                   

what are plants?

plants are biotic (living) component of ecosystem. they are as living as u and me. there are different habits of plant like, they may be herb, shurb, tree or may be climber. they do not show locomotion (move from place to place) but show movement of its parts. plants depends upon certain factors that required for its growth like suitable temperature, PH, soil chemical composition, nutrients quantity. they show great interaction with environment. plants compete with themselves for the resources.
