$A$ : Bast fibres are collenchymatous fibres.
$R$ : Fibres are absent in secondary phloem.

Read the following four statements $(A-D)$:
$(A)$ Both photophosphorylation and oxidative phosphorylation involve uphill transport of protons across the membrane.
$(B)$ In dicot stems,a new cambium originates from cells of pericycle at the time of secondary growth.
$(C)$ Stamens in flowers of Gloriosa and Petunia are polyandrous.
$(D)$ Symbiotic nitrogen fixers occur in free-living state also in soil.
How many of the above statements are right?

Draw illustrations to highlight the anatomical differences between:
$(a)$ Monocot root and dicot root
$(b)$ Monocot stem and dicot stem

Explain plant anatomy and its importance.
