Q. Go through the following pairs and choose the correct pairs from the option given below I. Nerium Sunken lower epidermis of leaves to stomata reduces loss of water II. Calotropis Non-succulent Root cells with thickened cell walls III. Peperomia Leaf succulent Leaf epidermal cell, store water IV. Ammophila Dicot Curl their leaves to minimise loss of water V. Tribulus Ephemeral Water is stored in stem
A) All pairs are correct
B) I, II and III are correct pairs
C) IV and V pairs are correct
D) I, IV and V are correct pairs only
Explanation
Plant, which grows in xeric habitat have sunken stomata in their lower epidermis of leaves to minimise the loss of water like Nerium succulent or drought avoiding plant store water (when available in excess) in the form of mucilage, i.e., leaf succulent, while true xerophytes are not succulent, like Calotropis
