Give reasons for the following:
$(i)$ Cells of sclerenchyma tissue have a narrow lumen.
$(ii)$ Branches of a tree move and bend freely in high wind velocity.
$(iii)$ It is difficult to pull out the husk of coconut.

(N/A) $(i)$ Sclerenchyma cells have extremely thick cell walls due to the deposition of lignin,which significantly reduces the internal space or lumen of the cell.
$(ii)$ Branches of a tree contain collenchyma tissue,which provides mechanical support and flexibility,allowing them to bend without breaking in high wind.
$(iii)$ The husk of a coconut is made of sclerenchyma tissue,which consists of dead,thick-walled,and tightly packed fibres that provide great strength and rigidity,making it difficult to pull apart.
