In which type of vascular bundles are Xylem and \(\mathrm{Phloem}\) present at the same radius?
1 Radial
2 Closed
3 Conjoint
4 Exarch
Explanation:
Exp:C Vascular bundle with phloem and xylem present on the same radius is called conjoint. Xylem and phloem are collectively known as vascular bundles. Xylem transport water and minerals from the roots to the entire plant body while phloem has the responsibility to transport the organic food inside the body of the plant.

Multiple epidermis on dorsal and ventral side of the leaf is found in
1 Zea mays
2 Triticum aestivum
3 Mangifera indica
4 Nerium oleander
Explanation:
Exp:D In nerium leaf multi layered numerous small opening called stomata are found in the epidermal layer of the leaves stomata are found in most abundance in the lower epidermis of the dorsiventral leaf they are sometimes together absent.

A vascular bundles without pith is
1 Protostele
2 Siphonostele
3 Solenostele
4 None of these
Explanation:
Exp:A A vascular bundle is without pith is called protostele, which consists of xylem and surrounded by phloem and pericycle. Protostele is most primitive stele it consists of a solid core of xylem surrounded by the phloem and the pericycle. Protostele is a type of stele, in which the vascular tissue in the stem forms a solid core, with no central pith.

A few drops of sap were collected by cutting across a plant stem by a suitable method. The sap was tested chemically. Which one of the following test results indicates that it is phloem sap?
1 Acidic
2 Alkaline
3 Low refractive index
4 The absence of sugar
Explanation:
Exp:B The phloem sap is alkaline in nature with \(\mathrm{pH}\) ranging from \(7.3-8.5\) and contains high levels of \(\mathrm{K}^{+}\) and \(\mathrm{Mg}^{2+}\). Hence the chemical test for alkalinity will help to identify that the exudated sap is phloem sap, as protons are pumped from companion cells to the neighbouring cells for the translocation of the sugars.
