*       Terrestrial Plants

 

Plants that grow on land are called terrestrial plants. Terrestrial plants are of different types depending on the condition they grow in.  

 

*         Plants on Mountains

Plants on mountains and hills are tall, straight and have slopping shape to make the snow fall off easily. They are usually flowerless and have cones with seeds inside them. The leaves are needle like with waxy coating. For example, fir, deodar, pine, cedar, small flowerless plants like ferns, lichens and mosses etc.

*         Plants in the Plain

These plants grow in plain, flat, surface of the earth. Trees have several branches and leaves. Many of these plants grow in warmer climate of the plains and shed most of their leaves in autumn. Example, Neem, Peepal, Ashoka and Mango.

*         Evergreen Plants

The evergreen plants of the plain are those which grow in hot and wet climate.

Example, Tea, Coffee, Rubber.

*       Plants in Deserts

Desert is a place with hot weather, very little water and scanty rainfall. Plants growing in these places are called desert plants. These plants develop certain features that help them to survive the harsh conditions of the desert. Roots are spread out just under the surface of the soil to catch the smallest amount of water. These plants have leaves in the form of spines or don't have any leaf at all to prevent water loss. Desert plants store water in its stem. Stem carry out photosynthesis. The plants use water stored in their stem when no water is available. For example, cactus, babul, kikar

                                                                              

                   Cactus                                                                                                     Babul  

 

*         Plants on Sea Cost

These are the plants that grow on the sea cost. Here the water is very salty and area has high rainfall examples coconut arch, nut.

*         Plants in Area with Heavy Rainfall

They are the evergreen plants and remain green almost round the year. Example rubber, teak, rice, cotton and sugarcane.

                                             

         Orchid                                              Cotton                                                        Rice  

 

*       Plants in Marshy/Swampy Area

The place, where the soil is very clayey and sticky is called marshy area and the plants growing there are the marshy plants. Major problem for the growth of plant here is oxygen, which cannot reach the roots of the plants. To overcome this problem, plants here have breathing roots to absorb air. Example, mangroves.
