The island of Singapore produces over 2000 native species

submerged. Show by sketches what you mean by the 
zones of vegetation along the water margin. 
. Write a list of any plants you have found growing with 
their leaves submerged in water. How do such plants 
obtain the gases they require for respiration and 
photosynthesis? 
. What plants establish themselves most readily on stiff 
clay soils where there is very little humus? 
. What plants are most abundant where the soil is com- 
posed largely of decaying vegetation? 
What kinds of plants are usually found growing in 
regions much exposed to violent winds? 
What peculiarities may be noted in plants that usually 
have erect stems when such plants are growing in a 
district constantly swept by violent winds that almost 
invariably blow from the same quarter?
