Number 50 with reason please.
Q.50.  Mechanical tissues is undeveloped in:
a) Xerophytes
b) Hydrophytes
c) Halophytes
d) Mesophytes

Dear student

Please refer the solution below for the said query

The correct option is b.

The mechanical tissue is the type of tissue that supports a plant and its parts and provides them with mechanical strength against environmental pressure like wind. For example sclerenchyma tissue.
It is absent in aquatic plants called hydrophytes because they are protected from any physical injury by the buoyant nature of water. 

Hope this information clears your doubt about the topic.
