Specialised epidermal cells surrounding the guard cells are called
1 Lenticels
2 Complementary cells
3 Subsidiary cells
4 Bulliform cells
Explanation:
Exp:C Specialized epidermal cells surrounding the guard cells are known as subsidiary or accessory cells. They act as a buffer between guard cells and epidermal cells against guard cells expansion. Subsidiary cells: As defined subsidiary cells and guard cells, both are the modification and part of epidermal cells in which guard cells have chloroplast which are absent in surrounding subsidiary cells.

Closed vascular bundles lack:
1 Cambium
2 Pith
3 Ground tissue
4 Conjuctive tissues
Explanation:
Exp:A A closed vascular bundle means that there is a absence of cambium they are not capable of forming the secondary xylem and phloem tissue. - The cambium is a meristermatic tissue found in dicot stem and roots. - When it is present between xylem and phloem, the vascular bundles are called open and when it is absent there, vascular bundles are called closed.

A bicollateral vascular bundle has the following arrangement of tissues
Exp:A Bicollateral - Vascular bundle which possess both xylem and phloem are called conjoint vascular bundle. In bicollateral conjoint vascular bundles phloem are present on both outer and inner side of xylem e.g. Cucurbita. Outer Phloem \(\rightarrow\) Outer Cambium \(\rightarrow\) Middle Xylem \(\rightarrow\) Inner Cambium \(\rightarrow\) Inner Phloem
